The following information is of a technical nature. You need the information if you are interested in the details of implementation, or want to carry out enhancements yourself.

Object technology is used to create the interface between the SAP functions and the Workflow system.

During POS inbound processing, an IDoc of type WPUWBW01 is created. This contains the data that the central SAP System needs to process the goods receipts that were posted in the store.

The methods for processing work items are provided by business object IDOCPUWB (POS inbound goods movements). This object type represents the purely technical interface for executing work items, not a concrete IDoc.

Task groups are collections of standard tasks, workflow templates and other task groups that are used in a common context.

For this workflow, two technical solutions were implemented that are assigned to the following task groups:

• The single-step task for workflow linkage of store goods receipt are grouped together under task group 20000029.
• A revised version, in the form of a workflow template (implemented as of Release 4.6) is stored under task group 20000023.

If you want to use this workflow, you must select one of these two solutions in Customizing for POS Interface.
