 Setting Up the System Infrastructure

Purpose

Setting up the system infrastructure is a prerequisite for transferring data via Core Interface (CIF).

Since data is distributed between the partner systems, you have to identify each system within the system infrastructure. The logical systemis used for this purpose.

Caution Caution

Do not use the same name for more than one logical system.

End of the caution.

If data from different logical systems is to reference the same objects in the SCM system (for example, because you work with multiple ERP systems and one SCM system), two prerequisites must be met.

  1. Define a business system group (BSG). This step is always necessary. The BSG integrates different physical systems into a superordinate logical unit. To make the settings, in CIF Customizing in the SCM System , choose Start of the navigation path Basic Settings for Creating the System Landscape Next navigation step Maintain Business System Group. End of the navigation path

    Recommendation Recommendation

    If you create master data in the SCM system, we recommend that you assign this system to the same BSG as that used for the logical systems that contain the master data server. Only then can preliminary maintenance of the master data be carried out in the SCM system.

    Once you have transferred data, it can be problematic to subsequently change the BSG assignment.

    End of the recommendation.

  2. Set up mapping structures, in other words, maintain/activate user enhancements. For more information, see SAP Library on SAP Help Portal at Start of the navigation path http://help.sap.com Next navigation step SAP Supply Chain Management (SAP SCM) Next navigation step SAP Advanced Planning and Optimization (SAP APO) Next navigation step Integration via Core Interface (CIF) Next navigation step Technical Integration Next navigation step Core Interface (CIF) Next navigation step Setting Up the System Infrastructure Next navigation step Checklist for Setting Up the System Infrastructure Next navigation step Mapping: Technical Transfer Structures Next navigation step Customer Exits. End of the navigation path

To be able to uniquely refer to identical keys from different business system groups in the SCM system, the primary key is supplemented by the business system group key. For more information, see the documentation for the IMG activity mentioned above.

Prerequisites

At least one ERP system and one SCM system must be successfully installed.

Note Note

If the ERP system was previously used as a standalone system, it is possible that the system distribution (ALE) is not maintained sufficiently. Check whether ALE is active in your ERP system and maintain the logical system in Customizing in the ERP system, as necessary.

End of the note.

Process

You perform the steps necessary for setting up the system infrastructure. For more information, see Checklist for Setting Up the System Infrastructure .

Result

After you have completed the steps required to set up the system infrastructure, you can trigger the actual data transfer .
