Modification Concepts: IDoc Outbound Processing

Use

The following modification scenarios are available:

You use the standard IDoc but want to influence the construction of the IDoc.

You create a user-defined processing module, which you copy from the standard function module for the respective message type and adjust accordingly.

You activate the user-exit in the standard function module in order to influence the standard IDoc construction.

You use the standard IDoc but want to define when and to whom a transfer order item should be sent yourself. In this case, you do not use the standard flow of the interface.

You implement your own interface connection between the Warehouse Management system (WMS) and the external system.

You use a modified IDoc with user-defined segments and you want to trigger user-defined processing to construct the data in the segments.

You define your own IDoc segments in the standard IDoc and use the user exit fill your user-defined segments with data.

You use a modified IDoc with user-defined segments and want to implement IDoc construction yourself.

You define your own IDoc segments in the standard IDoc and create your own processing function module, which you copy from the standard function module of the relevant message type and adjust accordingly.

You use a modified IDoc with user-defined segments and do not want to use the standard flow of the interface.

You define your own IDoc segments in the standard IDoc and implement an individually defined interface connection between the WMS and the external system.

You use an individually defined IDoc with a new message type and have to implement IDoc construction yourself.

You define an individual IDoc and create an individually defined function module. Standard auxiliary function modules are available for this purpose.

You use a modified IDoc with a new message type and do not want to use the standard flow of the interface.

You define an individual IDoc and implement an individually defined interface connection between the WMS and the external system.

Features

Adjusting the Standard Function Module

The WMS prepares for the IDoc to be sent to the external system. The system constructs the IDoc in the relevant application function module, determines the partner (the connected system), and steers towards the ALE layer for further processing.

At this point, you have the first opportunity to intervene in the IDoc processing, by creating a customized function module.

You enter this function module in the Customizing for Warehouse Management under Interfaces ® External Systems ® Configure Warehouse Management ® Whse Management View ® R/3 -> External System ® Function Modules for IDoc Creation ® Assign.

The WMS uses the following function modules for constructing and sending IDocs:

Function modules for outbound IDoc processing

Function module	Description
L_IDOC_CREATE_WMTOID01	Transfer orders
L_IDOC_CREATE_WMRRID01	Group release
L_IDOC_CREATE_WMCAID01	Cancellation request TO
L_IDOC_CREATE_WMIVID01	System inventory records

Note

User exits are available in the function modules for adding individually-defined segments or influencing the standard IDoc construction.

Realizing an Individually Defined Interface Connection

You realize an individually defined interface connection in order to be able to decide yourself when communication with the external system should occur and to which external system the data should be sent.

Caution

In this case, the interface in the WMS should not be active.

You use the user exit Enhancement at End of TO Creation (MWMTO01) to implement an individually defined connection between the systems.

Defining User-Defined IDoc Segments

You define your own IDoc segments by choosing Tools ® Business Communication ® IDoc Basis ® Development ® IDoc Types. For more information, see Segment Editor.

Defining User-Defined IDocs

If you define user-defined IDocs (interim structure) via Tools ® Business Communication ® IDoc Basis ® Development ® IDoc Types, assign this IDoc to a new message type. For more information, see Defining New IDoc Types.

You create a partner profile for this message type.

Creating Individually Defined Send Function Modules

For creating individual send function modules, SAP provides the following function modules, which are already used in SAP send function modules.

Modification Concepts: IDoc Outbound Processing

Function module	Task
L_IDOC_HEADER_CREATE	Construction of the necessary EDIDC data per IDoc
L_IDOC_SEGMENT_CREATE	Construction of an IDoc segment
L_IDOC_SEND	Sending the constructed IDoc
L_IDOC_FETCH	For access to the data in your program after calling your IDOC_CREATE_....
