Enhancement to Dynamic Receiver Determination

Use

If data is exchanged between systems in your system landscape via a central XI system , you must make sure that the IDoc receiver (force elements) can determine the new receiving system dynamically if the system is switched .

SAP NetWeaver provides the relevant functions to determine the receiver dynamically in an XI system. The Defense Forces & Public Security component enhances this function in terms of component-specific requirements.

So that the current receiver can be determined in a system landscape with decentralized and temporarily offline systems, the central XI system always retains the current information about which system is the operative system of a force element or plant/storage location combination. If the receiver data of an IDoc in the sending system is obsolete due to an intermediate organizational change and no update has taken place, the XI system automatically replaces this data with the receiver data of the operative system. As a result, the current operative system becomes the IDoc receiver.

This enhanced receiver determination supports the message type /ISDFPS/PG (purchase requisition), which has been enhanced with a corresponding IDoc segment for receiver information:

Prerequisites

You are using SAP NetWeaver Exchange Infrastructure (SAP XI) Release 3.0 SP16 or higher.

You are familiar with the XI-specific synchronization mechanisms .

Features

In the central XI system, the system stores the assignment to the current operative system centrally in mapping table /ISDFPS/XI_FORCE for each force element or combination of plant and storage location.

You perform the initial load of values to this table from the central system using the application Initial Loading DFPS Central System XI (transaction /ISDFPS/XI_INIT_LOAD). For more information, see the report documentation for the application.
The system updates this data automatically with each system switch . For more information, see Inform Systems of System Switch

When the message is received in the current distribution process, the XI system compares the data from the IDoc segment with the current data in the mapping table and updates the receiver information if necessary.
