Configurable Process Scheduling

(CPS) Used in Transportation and

Shipment Scheduling of GATP -

Part 1

Applies to:

SAP SCM 5.0, 5.1, 7.0 and above.

For more information, visit the Supply Chain Management homepage.

Summary

This White Paper explains functioning of CPS. CPS is Configurable Process Scheduling. CPS is one way of configuring Transportation and shipment scheduling in GATP. CPS uses business processes which have activities and these activities have a start date and end date. CPS should be used in scenarios where Transportation and shipment Scheduling can not be achieved using Condition Technique. This is a part one and second part will have more complex scenarios.

Introduction

Configurable process scheduling is a cross-application function, which you can use to schedule several freely definable business processes according to your own rules.

Using CPS, SAP has given opportunity to configure dates such as Material availability date (MBDAT) or Goods issue date (WADAT). By using Time stream calendars cut-off time can be configured.

CPS uses Process Alias. Process Alias is the name of the business process example SCHEDL_SDD for sales order processing where many dates are required or PLANNING process where Goods Receipt and Goods Issue dates are derived.

Process alias refers to Scheduling Schema. There are two ways of finding Process Alias either by assigning it to item category or by condition technique.

“Note that assignment of the item category to the process alias is ignored if the system has previously found a process alias using the condition technique. “

You have set configurable process scheduling so that the system calculates at least the following derived date types:

Unloading date (ELDAT)

Delivery date (LFDAT)

Goods issue date (WADAT)

Loading date (LDDAT)

Material availability date (MBDAT)

Transportation planning date (TDDAT)

The dates must also be arranged in such a way that the following conditions are met:

The unloading date is greater than or equal to the delivery date.

The delivery date is greater than or equal to the goods issue date.

The goods issue date is greater than or equal to the loading date.

The loading date is greater than or equal to the material availability date.

The loading date is greater than or equal to the transportation planning date.

Scenario

Let us try to understand CPS from a sales order availability check and Transportation Scheduling.

Following example is the CPS Scheduling of sales order availability check.

In the activity Transport and Plan -- Duration is determined, all other activities such as. Load, Set up, Unload have only Calendar is Determined

Fig-1

Duration of Lead or Plan is determined due to condition record found for Plant = 3000 and Delivery Priority = 02

Fig 02



© 2010 SAP AG 5

Duration of Transport is determined due to condition record found for Transportation Group = 0001

Fig 3

The condition record values can be accessed by T code /SAPAPO/SCH_GCM - Edit Conditions for Configurable Process Scheduling

The maintenance group is defined in configuration, the maintenance context is GCM (Hard coded).

Configuration

In the ECC, Transportation Scheduling should be active for the sales document type.

The path is IMG--> Sales and Distribution--> Basic Functions--> Delivery Scheduling and Transportation Scheduling--> Define Scheduling By Sales Document Type

Fig 06

In SCM

CPS Configuration starts with defining activities in the Schema and later CPS works on the basic principle of Condition Technique.

1. Create Condition Table

2. Create Access Sequence

3. Assign Condition Table to Access Sequence

4. Create Condition Type.

5. Assign Access Sequence to Condition Type.

6. Create Procedure

7. Assign Condition Type to Procedure

8. Assign Procedure to Scheduling Schema and Activity Type

9. Create Condition Record.

IMG--> SCM Basis--> Configurable Process Scheduling--> Define Schema

Scheduling schema or procedure (eg. SCHEDL_SDD) is used within a process definition. The procedure is used to control the behavior of scheduling of a sales order or STO.

There is no need of defining a new Z schema as standard SAP delivered schemas are good enough.

Moreover SAP has hard coded Schemas in the scheduling programs

SCHEDL_SDD has following activities

LEAD

LOAD

PICK

SLEAD

TRAN

UNLD

In the following configuration, we can see what is the basis of Location, Duration, Calendar, Time zone determination. Example Location Determination: The start of activity TRAN is Location From and end of TRAN is Location To.

Fig 7

The priority of determining Class to determine Calendar / Duration/ Time zone is maintained here.

We can see that Calendar Determination, The first priority goes to Condition Records and then to Location Master Data.

Fig 8

The name of Scheduling schema should match with Process Alias. The process alias is mapped to workflow identifier.

The path to maintain Process Alias: IMG --> SCM Basis-- > Configurable Process Scheduling --> Process Definition --> Define Process Alias

The condition technique allows us to use the fields which are required by the business such as Ship To, Plants, Loading Group, Delivery Priority etc.

Fig 10

The following example explains how to influence the MAD (Material availability date) and define Transit time.

MAD date can be pushed by using activity LEAD

Transit Time can be determined by using activity TRAN

Create Condition Table

Select Application SCH and Usage DU .Usage DU is for duration.

Create Condition Type and assign Access Sequence to it

Define Determination Procedure

Procedure ZTPTGR and ZLEAD

And assign condition type ZTPT to procedure

Determine Assignment of Item Category to Process Alias

This configuration can be used if CPS needs to executed by certain item categories or in specific order types.

Fig 24

But process alias can be determined either by item category (Fig 24) or directly by Condition Technique Fig 23.

Incase of Stock Transport Order, there is no item category so system finds Process Alias using Condition Technique.

Now the condition record maintained procedure Z20 for activity LEAD is going to influence the MAD date and the condition record maintained procedure ZTPTGR for activity TRAN is going to influence Transit Time.

The usage CA or Calendar is mapped to Time stream calendars. We can use Time stream along with Factory Calendar to influence working time of Delivering location or working time of Receiving location (Customer –Ship To).

Time Stream Calendars can be used to influence the activities also example Start of TRAN. If we want PGI should happen on particular days we can control that using Time stream Calendars and assigning these calendars to appropriate fields.

Fig 25

Warning: You may get short dump if you try to look lots of records in change mode, the solution is look in display mode.

Maintaining these records is a pain, business may want easy solution, and using development condition records can be uploaded or deleted.

Time Stream Calendar can be maintained by T code /SAPAPO/CALENDAR - Calendar

Fig 26

The following example explains different calendars assigned to combination of Plant and Ship To. Z93 condition type is assigned to procedure Z93 . Procedure Z93 is assigned to activity TRAN and usage Duration.

Fig 27

The Customer 3250 will have Post Goods Issue date always on Friday and 100181 can be shipped on any day.

The following example is a sales order for Ship To 3250

Results in ECC show the PGI date on Friday, based on Requested delivery date of 08/04/10

The following example is a sales order for Ship To 100181

The condition record to determine Calendar is found using condition technique Fig 32.

Development in CPS Scheduling can be done in two of the user exits of SCM

EXIT_/SAPAPO/SAPLVCRM_001 : Scheduling: Inbound Interface

EXIT_/SAPAPO/SAPLVCRM_002 : Shipment Scheduling: Data Determination
