Prerequisites for the OLTP Scheduling Agreement

If you work with purchase scheduling agreements, you should note the following prerequisites in the SAP R/3 system:

Type of Scheduling Agreement(Planning and Releases in the SAP R/3 System)

The OLTP scheduling agreement in the SAP R/3 system is usually a scheduling agreement with the document type LPA , for which the Release Docu. indicator has been set under Start of the navigation path Scheduling Agreement Next navigation step Define Document Types End of the navigation path in Customizing for Purchasing .

As a rule, the APO scheduling agreement in the SAP R/3 system is a scheduling agreement with the document type LP.

Material Master

You should assign the MPR type X0 ( W/o MRP with BOM Explosion ) to the materials used. You do this in the material master, on the MRP 1 tab page.

Create and Activate Integration Model

Create an integration model containing the material masters, plants, scheduling agreements, vendors and storage location stocks. To transfer OLTP schedule lines as well as confirmations and shipping notifications against scheduling agreements to the SAP APO system select POs and PReqs .

Activate the model.

In the SAP R/3 system, choose Start of the navigation path Logistics Next navigation step Central Functions Supply Chain Planning Interface Core Interface Advanced Planner and Optimizer Integration Model. End of the navigation path

Release Creation

The delivery schedule lines for and releases against OLTP scheduling agreements are generated in the OLTP system.

To do this, the following conditions must be satisfied in the OLTP system (that is, the R/3 system):

In the additional data for the scheduling agreement item, choose the setting Generate and output SA release in R/3 for the External Planning indicator.

The OLTP scheduling agreement in the SAP R/3 system is usually a scheduling agreement with the document type LPA , for which the Release Docu. indicator has been set under Scheduling Agreement Define Document Types in Customizing for Purchasing .

Note
You should note that you must not have any items with different External Planning settings in a scheduling agreement because this leads to problems in the message determination process. In other words, all items of a scheduling agreement must be planned either in the SAP APO system or in the OLTP system.

End of the note.

Note
If delivery schedule lines already exist for an SA item, the setting for the External Planning indicator can no longer be changed.

End of the note.
Transfer the SA item to the SAP APO system over the APO Core Interface (CIF).

If you want to send unconverted purchase requisitions in the OLTP scheduling agreement release you must use the Customer Exit MEETA001 (EXIT _SAPLEINL_001). For more information and for example coding see SAP Note 409394.

Maintaining the Release Creation Profile

You define the release creation profile in Customizing for Purchasing under Start of the navigation path Scheduling Agreement Next navigation step Maintain Release Creation Profile for Scheduling Agreement with Release Documentation End of the navigation path .

You assign this release creation profile to the SA item in the detail data.

For APO scheduling agreements, you must create a separate release creation profile in the SAP APO system and assign it to the APO scheduling agreement in the external procurement relationship (in the SAP APO system).

Display last deliveries

This function is only available if you are using an SAP R/3 system (Automotive).

Prerequisites for the function are that:

You are using GR-based invoice verification ( GR-Based IV indicator in the SA item), or
You are working with a confirmation control key that provides for GR assignment (Customizing for Purchasing under Confirmations -> Set Up Confirmation Control -> Confirmation Sequenceand ConfContrKindicator in the SA item).

Furthermore, you must use a release creation profile for which you have specified determination of the last goods receipts in the OLTP scheduling agreement.( Start of the navigation path Scheduling Agreement Next navigation step Maintain Release Creation Profile for Scheduling Agreement with Release Documentation End of the navigation path on the Last Goods Receipts tab page .)

You can view the last deliveries when maintaining delivery schedule lines. Display the schedule lines for an SA release and choose to display the last deliveries.

Delete Procurement Scheduling Agreement

If you delete a procurement scheduling agreement in the OLTP system then the corresponding external procurement relationship is deleted in the SAP APO system.

For more information see Process External Procurement Relationship .

In SAP APO you can use the authorization object C_APO_EXPR to define which activities a user is allowed to carry out. For example, you can control whether a user is allowed to change master data.

Customer-Specific Enhancements and BAdIs

Numerous Enhancementsand Business Add Ins(BAdIs) are available for external procurement.

For more information on customer-specific enhancements for the APO Core Interface (CIF) see Customer-specific CIF Enhancements for the Procurement Process (SAP APO and SAP R/3) .

For more information on the CIF, see the SAP Library for Advanced Planning and Optimization (SAP APO) under Integration of SAP APO and SAP R/3 .
