M2798 - Overview

• Message type: E = Error

• Message class: M2 - LIS: Generating and updating info structures

• Message number: 798

• Message text: Segment definition of segment type &1 does not contain field &2

What causes this issue?

The segment definition of segment type &V1& does not contain the field
&V2& which is in the communication structure &V3&. The field names in
the segment definition and the communication structure must be
identical as the segment transfers the data to the communication
structure using MOVE CORRESPONDING.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the segment definition of segment type &V1& and the communication
structure &V3&.
You can either:
Create a segment type with a reference, where you use communication
structure &V3& as the reference. This ensures that the field names of
the communication structure and the segment definition are identical,
and the export length of the fields in the segment definition required
for the correct conversion of the various data types is determined.
or
Correct the communication structure &V3& or the segment definition of
segment type &V1& which is used in the IDoc enhancement &V4&.
