IDoc Reduced Segment Check

IDoc Reduced Segment Check: SAP offers some standard functions to check if a Segment can be reduced for Specific message type and even check if the Segment’s field reduction is active.

How to IDoc Reduced Segment Check

Check IDoc Segment Active BAPI

Given a message type, some time is important to check if a specific segment is reduced.
Once the check passed, data can be retrieved for the segment and the segment can be generated.

The Standard SAP BAPI IDOC_REDUCTION_SEGMENT_TEST (ALE: IDoc-Reduction / Segment-Test)

The signature of the IDOC_REDUCTION_SEGMENT_TEST is:

• IMPORTING

  • VALUE(SEGMENT_TYPE) LIKEEDI_IAPI02-SEGTYP
• EXPORTING
  • VALUE(ACTIVE)
