<ZH>&CAUSE&</>
The data part of table/view &V1& contains a field whose output length is
longer than 255 characters. You cannot put such fields in BC Sets.

System Response

The table/view is not forbidden in BC Sets, but the field is not
proposed for the BC Set in the BC Set maintenance transaction (SCPR3).

How to fix this error?

This is not a table/view design error. Such fields cannot be put in BC
Sets because of the current BC Set design. The SAP developer responsible
for the table/view can:
If it is possible without too much effort, adjust the table/view in the
Dictionary so that there are no more fields longer than 255 characters.
Regenerate any maintenance dialog (SE54).
These changes will usually require a lot of effort. You can confirm the
restriction in the BC Set compatibility check. The BC Set functionality
for this object is not deactivated, the field is not proposed for the BC
Set in the BC Set maintenance transaction (SCPR3).
<ZH>Note</>:
Test the BC Set functionality to ensure that the data is correct.
Create a BC Set for the object.
Check that the data has been completely recorded in the BC Set (SCPR3).
Change an entry in the object (SPRO or SM30/34).
Activate the BC Set (SCPR20).
Check whether the values in the BC Set have been written correctly into
the table/view.
