How To Fix SCDT_MPNG1027 - Source table &1, field &2: Possible data loss in distribution

SCDT_MPNG1027 - Overview

• Message type: E = Error

• Message class: SCDT_MPNG1 - Message Class for the Function Module scdt_mapping_check

• Message number: 027

• Message text: Source table &1, field &2: Possible data loss in distribution

What causes this issue?

The field &V2& in the source table &V1& is longer than the assigned
target field &V3&. The Customizing Distribution converts the contents of
the source field into the format of the target field (by ABAP MOV E).
If the source and target fields are of type CHAR (character string), the
Customizing Distribution does not distribute the end of the source
field. This can cause data loss.
If the source and target fields are of other types, the conversion and
the Customizing Distribution can fail.

System Response

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 whether you can use another target field. Ensure that truncating
the contents will not cause problems (e.g. in text fields).
