How To Fix S_CUS_IMG_ACTIVITY193 - Table &1 in object &3 contains the forbidden key field '&2' (String)

S_CUS_IMG_ACTIVITY193 - Overview

• Message type: E = Error

• Message class: S_CUS_IMG_ACTIVITY - IMG Activity

• Message number: 193

• Message text: Table &1 in object &3 contains the forbidden key field '&2' (String)

What causes this issue?

The table/view &V1& in object &V3& has a key field ('&V2&') of type
'STRING' or 'XSTRING'.

System Response

You can use object &V3&, except for the table/view &V1&, in BC Sets.
Fields of type 'STRING' are not supported in BC Sets. If there are such
fields, as here, in the key of a table/view, you cannot put them in BC
Sets.

How to fix this error?

This is not a table/view design error, i.e. a key field can be of type
'STRING'/'XSTRING'. 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 not of type 'STRING' or 'XSTRING'.
If the table/view has a generated maintenance dialog, regenerate it in
transaction SE54.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
