How To Fix S_CUS_IMG_ACTIVITY194 - Table &1 in object &3 contains key field '&2' (> 255 characters long)

SAP Error Message - Details

• Message type: E = Error

• Message class: S_CUS_IMG_ACTIVITY - IMG Activity

• Message number: 194

• Message text: Table &1 in object &3 contains key field '&2' (> 255 characters long)

What causes this issue?

The table/view &V1& in object &V3& has a key field ('&V2&') which is
longer than 255 characters.

System Response

You can use object &V3&, except for the table/view &V1&, in BC Sets.
Fields with an output length of more than 255 characters are not
supported in BC Sets. If such fields, as here, are in the key of a
table/view, you cannot put it in BC Sets.

How to fix this error?

This is not a table/view design error. A key field can be longer than
255 characters. Only restrictions in the BC Set technology prevents the
use of such tables/views in BC Sets.
If you want to use the table/view in BC Sets, the SAP developer
responsible for it must change its design in the Data Dictionary,
replacing the field by one which is < 256 characters (output length)
long. If the table/view has a generated maintenance dialog, regenerate
it in transaction SE54.

Procedure for System Administrators
