How To Fix CACSDESGEN203 - Generated objects must not be used as source for additional fields

CACSDESGEN203 - Overview

• Message type: E = Error

• Message class: CACSDESGEN - Messages From Construction

• Message number: 203

• Message text: Generated objects must not be used as source for additional fields

What causes this issue?

Additional fields are always specified in the application design with
reference to a field in an existing structure (similar to LIKE
in ABAP).
For reasons of stability, reference to fields of generated structures is
not permitted, consequently you cannot include generated objects in the
field selection (hierarchy on left).

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?

Every additional field stems originally from a non-generated structure.
So you should use the corresponding structure. You can see the origin of
a field in field TCACS_DESFIELDS-FROMTAB ("name of table from which
field was copied").
If you apparently copy from a generated structure (by vertical drag and
drop in the hierarchy on the right), the "real" original object is
determined.
