SAP Business Workflow
SAP Business Workflow® is a cross-application tool that makes it possible to integrate business tasks/processes between applications.
This tool was introduced in R/3 Release 3.0A, and received a substantial facelift in the Enjoy Release, 4.6A,which warranted the new name Workflow Builder.

Need of Workflow
Hmm ! Time to put in a purchase requisition request
1
3
I guess I’d better send off some inter-office mail to ask the approvers to approve my requisition.
2 I wonder whoapproves buying this stuff?
5
Time drags on . . .Meanwhile, in Mr. Manager’s office . . . “What shall I do next?”
4
TIME IS MONEY!!!
|
Drawbacks
Inefficiency.
Each lacks a way to trace where a task is.
Who executed or is executing it.
How much time it required.
|
Why SAP Workflow
Workflow ensures that the right work is sent to the right person at the right time in the right sequence with the right information.
Tool for the automization of business processes Not tied up to any paricular application Operates uniformly accross applications Coordinate all participating tasks Provide users with active support Intelligent routing

Workflow Definition
Workflow definition consists of
1. Basic Data2. Information about triggering events3. Initial Values4. Containers5. Bindings
A workflow definition describes the workflow process
|
Workflow Builder
The workflow definition is created in the Workflow Builder and displayed graphically in a network.

|
Workflow Definition - Steps
A workflow definition is made up of individual modular steps.
|
Example Workflow Create a simple workflow
|
How are Workflows Created in a System
Within workflow templates, there is a key with the following structure:- A WS task abbreviation for the workflow template- An 8-digit sequence number
From the structure of the 8-digit number, the system knows whether the template is a standard template delivered by SAP or one created by the customer.
Customer-defined templates start with the prefix number that was defined in Customizing for the system and client.

Workflow Steps
|
Workflow definition steps
Workflow definition is made up of individual steps. When creating a step in a workflow definition, the step type must be specified first.
There are 1. Steps which refer to business activities (activities & user
decision)
2. Steps which are used for internal process control and monitoring (condition, multiple condition, loop, etc)
|
Business Activities Steps Activity
Can be a single step task with basic business functionality Can be a multi-step task, which reference to a workflow definition
User Decision This provides an opportunity for user interaction with the system. The response to this decides the selection of the subsequent step.
Document from template PA document is created from a document template using variables in the text that are
filled during program execution.
Web Activity Selected container elements are posted using http protocol in XML or SOAP message
Subworkflow An activity which refers to a workflow rather than a task
|
Internal process control Steps Condition
Branch on the basis of control information from the runtime dependent context of the workflow.
An attribute of this object can also be accessed for condition evaluation Condition evaluation can be done by
Field comparison e.g constants , object attribute, system fields
Multiple condition In contrast to condition, multiple condition makes it possible for the
workflow definition to branch in more than two branches.
For evaluation of the multiple condition, the value of the basis of comparison is checked at runtime against the comparison values and branched accordingly.
|
Internal process control (contd.)
WHILE Loop Steps are processed repeatedly until the conditions contained in the
WHILE step no longer apply.
Until Loop Steps are processed repeatedly until the condition contained in the
UNTIL step is true.
Fork Used for parallel processing branches. Only a part of the parallel processing branches actually has to run to
continue the workflow. Dynamic parallel processing is also possible
|
Internal process control (contd.)
Send mail- Text entered in this step can be used to send a mail to the agent assigned
Container operations- Used to perform arithmetic operation of value assignment to workflow
container elements using constants and data in the workflow container .
|
Internal process control (contd.)
Event Creator An event is created when this step in the workflow is reached. Other workflows can be started as a reaction to the event
created in this step. This event must be the triggering event of the relevant workflow tasks and/or templates.
WAIT for event Used to stop the whole execution of the workflow until the
event is created in the system. Used to wait for events for parallel processing

Single-step tasks
ƒ Single-step tasks describe elementary business activities.
ƒ Single-step tasks operate on an object and refer to one object method
each
ƒ Single-step tasks are linked to their possible and permitted agents
whose organizational assignments are described in the organizational
plan of the enterprise.
ƒ Executable single-step tasks are represented by work items at runtime.
|
Workflow definition - Multistep tasksƒ A workflow definition has a modular structure consisting of individual steps
which are linked together.
ƒ The multistep tasks form the business framework for a workflow definition and each references one workflow definition.
ƒ A step in a workflow definition can be an activity.
ƒ An activity always refers to one task (= single-step task or multistep task).
ƒ An activity with one simple triangle refers to a task.
ƒ An activity with three triangles refers to a workflow (subworkflow).

|
Work Itemƒ Executable single-step tasks are represented by work items at
runtime.
ƒ Object that represents a task or action in the workflow system at runtime.
ƒ Depending on the work item type, some of these work items are displayed in a user's work list. Other work items, on the other hand, are only used and processed internally.
ƒ The work items are displayed in the integrated inboxes of their selected agents, and can be reserved and executed from there.

Business Object Definition and Implementation
|
ƒ SAP Business Workflow has been developed on an object-oriented basis.
ƒ The business object types are identified and described with their object methods in the Business Object Repository(BOR) of the R/3 System.
ƒ Generally one object is created in the system and then processed in a workflow over several steps by various employees.
Object Types & Workflow
|
Workflow deals with object types. Object types are definitions of data. In order to access database data, workflow uses the object type interface.
Most of the information represented by object types is available in the ABAP/4 Dictionary.
Objects are created at runtime and are specific instances of defined object types.
Many object types are delivered by SAP. In addition, the customer can create new object types or extend SAP objects by creating subtypes (child objects). New customer objects or subtypes may be desired if the delivered SAP object does not contain all the characteristics (attributes) or processing options (methods) desired.
Object Types & Objects
|
Object Type - Definition
|
Interfaces
Interfaces are a combination of attributes, methods, and events to be used in common among multiple object types. The purpose of interfaces is to define common functionality in one object type, and to assign that common functionality via an interface to multiple object types across the Business Object Repository. This avoids redundancy of data and functionality definition.
Each new object type automatically receives the interface IFSAP, the SAP standard interface. IFSAP provides every object type with the following:
Method Display Method ExistenceCheck Attribute ObjectType
|
Key Fields
Key fields are designed to uniquely identify the object type.
If the key field has a data type reference of a dictionary table field, the runtime system will look to that table field to retrieve the value of the key when processing the object. When the key field is created, the ABAP/4 program code is generated automatically when the object type is generated.
|
Attributes
Attributes provides access to data.
ABAP Dictionary Field Virtual
|
MethodsMethods incorporate the permitted functions available for an object.Methods have importing and exporting parameters as well as exceptions.
Methods can be created using :
|
– Dialog / or background :
Execution of the method is via a work item in a user’s integrated inbox or in background by the workflow runtime system. Background methods cannot use messages or exceptions because they cannot be processed by the background system and will result in termination of the program.
– Synchronous / Asynchronous • Synchronous methods finish executing before handing
control back to the calling program. These types of methods can return export parameters, results and exceptions. Asynchronous methods do not return control to the calling program immediately. Once executed, they depend upon events to communicate the results of the method back to the calling program. Asynchronous object methods cannot have results, export parameters or exceptions.
Methods - Call attributes
|
Result:
Synchronous methods may return an export parameter as a result. A
result can be defined like a dictionary field or an object type .
Instance independence:
Indicates whether an object reference is passed to the method by binding
at the time of execution. Methods that generate and return an object
reference, such as Create, or methods that generate a report listing should
be instance independent.
Methods - Call attributes
|
Import /Export Parameters
• The method parameter container contains references to all import, export and result parameters which need to be exchanged back and forth between the calling program (single-step task) and the method. Binding is necessary between the single-step task and the method parameter container to accomplish the data transfer.
• Import parameters are those values which are necessary to execute the method. Import parameters are retrieved from the container CONTAINER using the macro instructions SWC_GET_ELEMENT (single-line) or SWC_GET_TABLE (multiline).
• Export parameter values are passed to the container CONTAINER using the macro instructions SWC_SET_ELEMENT (single-line) or SWC_SET_TABLE (multiline). The result parameter is passed to the CONTAINER element RESULT via the same macro instructions.
|
Exceptions• Error handling is accomplished through the use of method exceptions
(synchronous methods only).
• The workflow definition can branch according to these possible error states and allow for subsequent steps to handle these conditions. Messages and exceptions cannot be used with background methods because they will terminate the program.
• Number of the exception: • 0001-1000: exceptions defined for interfaces• 1001-7999: application-specific exceptions (free for SAP
development)• 8000-8999: exceptions raised by the object manager• 9000-9999: exceptions defined by the customer (free for
customers)
|
Exceptions
• Exceptions are implemented within a method, between the macro instructions BEGIN_METHOD and END_METHOD.– EXIT_RETURN Code Variable1 Variable2 Variable3 Variable4.
• Code = the 4-digit number of the exception• Variable1 through Variable4 correspond to up to 4 variables
which can be derived from the message issued with the exception.
• The following exceptions (for temporary errors) are also available to allow exiting of the program:– EXIT_OBJECT_NOT_FOUND = object not found– EXIT_CANCELLED = cancelled by the user
|
EventsEvents describe the change in the status of an object.Workflow are usually started using events
|
Object Type - Release Statusƒ Not accessible at runtime.
ƒ Only in test or internal use, possibly unstable.
ƒ Released for use by the customer.
ƒ The functionality has been replaced. The old functionality is still supported for two releases.
|
Subtype
The subtype inherits all attributes, methods and events of the supertype and is open for new customer-specific attributes, methods and events. The key fields of the supertype and subtype must be identical. This means that any methods and attributes defined on the parent can be executed and accessed on the child object.
|
Delegation
This delegation is powerful because it lets you implement your own business logic without modifying any SAP code. As long as the objects are properly delegated, your method will be executed.

Containers and Bindings- Workflow -
|
Types of Containers
|
Workflow Container
ƒ The workflow container contains workflow-specific system variables and other elements which are defined explicitly.
ƒ As part of the definition of the workflow task, the import and export parameters of the workflow are defined as elements of the workflow container.
ƒ When the workflow is defined in the workflow editor, elements can also be added to the workflow container. These elements are then "local variables" within a workflow definition and can be used, for example, to set up a counting loop.
|
Task Container
ƒ Each task container already contains the workflow system variable and any additional elements for the method parameters of the referenced object method.
ƒ You have to add additional elements to the task container for additional values are required for variable replacement in the work item text or in the long texts
|
Other Types of Containers
Event parameter containerContains an element which can take the (object) reference to
the objectwhose change of status is announced via the event.
Role parameter containerContains the elements required as input in connection with the
roleresolution to be run at runtime.
Method parameter containerContains elements which will be required as import and export
parametersin connection with the method execution.
|
What is a Container?
• Field values
• Multiline lists of field values
• Object references

Binding
ƒ A binding is simply the art of pouring selected container elements from one container into another.
ƒ The binding editor is available when defining: Workflow definitions Triggering events Workflow steps Workflow steps ( Standard roles/ Object methods with parameters)
ƒ The binding editor always references the container to receive the application data. Binding definitions can reference:

Declare a variable as an internal table object:DATA: REQITEMS TYPE SWC_OBJECT OCCURS 0.
Create an instance of your object for each table line:SWC_CREATE_OBJECT REQITEM ‘BUS2009’ PREQKEY.
Once the internal table is filled, transfer the internal table to the multiline container element:
SWC_SET_TABLE CONTAINER ‘PRItems’ REQITEMS.
Since this internal table has no header, declare a work area: DATA: REQITEM TYPE SWC_OBJECT.
Declare key fields of the object(e.g. called PREQKEY) and fill them
(e.g. within a select loop).
Append the object instance to the internal table:APPEND REQITEM TO REQITEMS.

Reading Container Elements Defined as Multiline Object Types
Container Instance:
CONTAINER
Object Element:PRItems
Read value of multiline container element into your internal table object:
SWC_GET_TABLE CONTAINER ‘PRItems’ REQITEMS.
Declare your object:DATA: REQITEM TYPE SWC_OBJECT.
Loop through your internal table object REQITEMS into individual REQITEM entries.
Perform operations as needed.
Use this macro to get the keys of each entry:SWC_GET_OBJECT_KEY REQITEMS PREQKEY
Use this macro to get the object type of each entry:SWC_GET_OBJECT_TYPE REQITEMS OBJTYPE.
Declare a variable to hold the object type:DATA: OBJTYPE LIKE SWOTOBJID-OBJTYPE.

Events
|
Event
An event describes a possible status change for an object in the SAP System.
Before an event can be used in a workflow, it must be defined in the Business Object Repository for the object type.
Events must be triggered explicitly. The application itself can be the triggering agent.

Organisational Structure
|
Organizational Structure Business Scenario
ƒ An organizational plan in SAP describes the organizational structure of a company.
ƒ The workflow system finds the agents of the individual tasks by evaluating the organizational plan
ƒ The functions to create and maintain organizational plans are part of the Personnel Planning and Development (PD) part of the SAP HR module
ƒ You must connect this organizational structure to the workflow
|
ƒ Organizational units contain positions, occupied by employees.
ƒ Jobs are abstract descriptions of task assignments.
ƒ Positions can be linked to jobs. They inherit all the tasks assigned to that job.
ƒ Users. A user is an SAP logon user ID. It thus represents a single person.
ƒ Persons. A person is a specific employee created in the HR module.
ƒ Workflow tasks can be assigned to organizational units, positions, jobs or users.
ƒ The workflow system uses organizational structure to route work items to the correct recipients

Agent Assignment and Role Resolution
- Workflow -
|
Agent
Agent is an executor of a work item.
ƒ Agent is responsible for executing a task in a workflow.
ƒ Agent is determined by the system either through organizational chart or directly if user is assigned as agent for a particular task.
ƒ If the agents of the individual workflow steps are determined using the customer-specific organizational chart, your agent assignment in the workflow remains flexible to change.
|
Types of Agents
Deadline Agents
Notification Agents
Processing Agents
Selected agentsare those possible agents who are elected to execute a task at runtime
Possible agentsare a collection of agents who qualify to execute a work item
Actual agent is the agent among those selected agents who actually processes the work item
|
Role Resolution
List of possible agents (executors) of a task(All supervisors in a dept.)
Selected Agent(s)(Mr. Banning)
Role Resolution
(Supervisor of User PBACON)
Role = Rules
A role defines rules by which selected agents can be determined at runtime through role resolution. Role resolution restricts the number of possible agents.
|
Standard Rules
A rule container is defined for each rule.
The rule parameters determine which information is required for the rule resolution to be executed at runtime.
If an error occurs during rule resolution, setting the termination indicator for the rule resolution determines how the workflow will continue:Flag is selected - the workflow assumes an Error status and a notification is sent to the workflow administrator.Indicator is not activated - the workflow forwards this work item to ALL possible agents.
|
Rule Basics
Transaction : PFAC_INS(Create)Menu Path: Tools – Business Workflow – Development – Definition tools – Rules for Agent Assignment – Create/Change/Display.
Each rule gets a 8 digit generated by the system prefixed with ACRules can be tested using PFTC or by function module ‘RH_GET_ACTORS’
|
Rule Definition in a Activity Step Type
Various options to create standard rules :
1. Responsibility (Pure configuration no ABAP coding) Defined Value ranges are assigned to Agents Data is filled from workflow container at runtime
2. Evulution paths (Pure configuration no ABAP coding)
3. Organizational data (Pure configuration no ABAP coding) Jobs , positions
4. Functions to be executed – ABAP Code – Function Module
|
Via organizational objects: Role resolution utilizing organizational data analyses

Active monitoring allows to specify threshold values for the state of the systemFor e.g threshold can be on the number of IDocs in error or the time limit
Report Program RSEIDOCA can be executed periodically Selection screen takes as input the threshold values and persons to be notified When defined threshold is exceeded Single Step Task TS30200088 is executed
|
Setting up Inbound Process via Workflow
The standard system can be configured to start a WF for an incoming IDoc. Useful when review is essential before posting Custom. SAP does not deliver standard. The settings are: --Create the custom task or WF --Create a new process Code ( WE42) and attach this custom WF/Task. --In the Partner Profile, attach the new Process code
|
Notification of Successful Posting
The ALE/EDI interface can raise events on successful posting of an IDOC. The settings are:
--Identify the Appl.Obj created by the Idoc. Txn: WE57
--Identify the event that needs to be raised. --Go to BD67, select Process code and
populate Object type and Event. --Identify/Create tasks/WF and enable event
linkage.
|
ALE error handling
Necessary Steps: Create new object type in Business Object Repository for IDOC; object
is child of IDOCAPPL Create new customer task Create event-couplings linking
Event ‘inputErrorOccured’ linked to standard task Event ‘inputFinished’ to function module
To support mass processing: Create new object type as child of IDOCPACKET
Maintain process code to refer the above objects and events
