How To Fix M2797 - Communication structure &1 does not contain field &2

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 797

• Message text: Communication structure &1 does not contain field &2

What causes this issue?

The communication structure &V1& does not contain the field &V2&, which
is in the segment definition of the segment type &V3&. The field names
in the segment definition and the communication structure must be
identical, as the segment transfers the data to the info 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 the segment type &V3& and the
communication structure &V1&.
You can either:
create a segment type with a reference, for which you use the
communication structure &V1& as a reference. This ensures that the
field names of the segment definition and the communication structure
are identical, and that the export length of the fields necessary for
the correct conversion of the various data types is determined in the
segment definition.
You correct the communication structure &V1& or the segment definition
of segment type &V3&, which is used in the IDoc enhancement &V4&.
