The Concept of HR/Payroll Features (Decision Trees)

What are HR/Payroll features? Features are decision trees designed to allow you to configure the

logical determination of data entry values

Decision trees allow for a reduction and/or elimination of dataentry errors and required intelligent key strokes

When and where are HR/Payroll features relevant?

Features are programmatically (ABAP) executed at dialog entry

time as the various types of master data information (infotypes)

are created (not effective dated)

The features available to be used and configured for any

particular infotype can easily be determined and verif ied throughthe use of the standard SAP debugger functionality

Not directly relevant to the gross-to-net payroll accounting, but

indirectly via the stored master data

Example Maintain/Display HR/Payroll Feature ABKRS

Transaction PE03 is used to display and/or maintain(configure) the decision tree

Where

toFIND it


8/73

8

Example HR/Payroll Feature (Decision Tree) ABKRS

In this example, the decisiontree will default a payroll

accounting area value of 12

(weekly) for the FTNon-Exempt employee

A value of 13 (bi-weekly) will

be defaulted for the FT ExemptCorp employee

The features are configurable

specific to customers needs


9/73

9

When Do the Features (Decision Trees) Execute?

In this example, the decisiontree used the employeegroup value and theemployee subgroup value to

determine the correct payrollaccounting area when theinfotype 0001 (organizational

assignment) was created.This results in a value of 12(weekly) being defaulted forthe payroll accounting area


10/73

Feature (Decision Trees) Determination and Verification Steps

Prior to creating or changing an infotype, initiate the menupath or SE37 (function builder) transaction to display theHR_FEATURE_BACKFIELD function. Set a breakpoint.

The Concept of Schemas Payroll Flow Control

What are schemas and subschemas? The schema controls the flow of payroll accounting

The schema is organized in a logical manner to easily reflect

the normal flow of gross to net, and the recursive loopingrequired in the case of a zero net check

The schema is configurable to allow for the flexibili ty of your

business needs and requirements. What is the RPCALCx0 program?

The RPCALCx0 program is not a top-down program, but a

warehouse of code to be chosen to be executed by theschema

What Are the Various Types of Standard Schemas?

Following is a list of the SAP standard schemas suppliedfor various functional reasons. Regardless of the specificschema, each controls the flow of programming to beselected from the warehouse of code stored in theRPCALCU0 program

The Concept of Payroll Functions (ABAP Code)

The Concept of Payroll Functions (ABAP Code)

What are payroll functions? The function is a logical block of ABAP code that is

contained in the RPCALCU0 warehouse of code

When and where are payroll functions relevant? The use of a functions is configured in the schema and

subschemas and executed at payroll processing time

We wil l learn how to f ind and research the ABAP code

associated with any payroll function

The use of a parameter for a function is configured in the

schema and subschema

We will learn how to determine which parameters are

available for use with any payroll function

In this example, the UBD0 subschema will control theflow of payroll accounting based on the use ofSAP-supplied functions

The Concept of Payroll Calculation Rules (Configuration)


35/73

35

p y ( g )

What are payroll rules? Standard calculation rules are provided by SAP as a baseline for

gross-to-net payroll accounting

Rules are configurable, and customer-specific rules can easily becreated to solve complex business requirements and problems

The calculation rules can be wage type specific or generic

The calculation rules can be based on the type of employee,salary exempt, salary non-exempt, hourly non-exempt, etc.

The SAP calculation rules (cycles) are your friend and the

technical strength of flexibility

To determine and understand the ABAP code that is beingexecuted for any specific calculation rule, first you must

execute payroll, and then set a breakpoint at the FUPITfunction, as shown in the next sl ide

The setting of a break in the schema and/or subschema,

which wil l be specific to a user, requires the creation of anAB4 parameter. This is created via the path of: System >

What are calculation rule operations? The operation is a logical block of ABAP code that is contained in

the RPCALCU0 warehouse of code

rule and executed at payroll processing time

We will learn how to find and research the ABAP code associatedwith any payroll operation

Operations are objects of SAP ABAP code that you have

The parameters used for operations tie to SAP ABAP code

that you have purchased and can choose to use or not to

The integration of the wage type processing in payroll

accounting is a primary example of how these buildingblocks tie together to achieve a complete, compliant, and
