How To Fix S_CUS_IMG_ACTIVITY244 - Table &1 in object &3 contains forbidden field '&2' of type String

S_CUS_IMG_ACTIVITY244 - Overview

• Message type: E = Error

• Message class: S_CUS_IMG_ACTIVITY - IMG Activity

• Message number: 244

• Message text: Table &1 in object &3 contains forbidden field '&2' of type String

What causes this issue?

Switch BC-Sets: Table/view &V1& in object &V3& contains a 'STRING'- or
'XSTRING'-type field ('&V2&').
'STRING' -type fields are not supported by BC sets.

System Response

Object &V3& cannot be used in switch BC sets because not all subobjects
can be included in switch BC sets.

How to fix this error?

This is not an incorrectly designed table/view. Principally, a field can
be of the 'STRING'/'XSTRING' type. However, because of BC set technology
restrictions, this table/view cannot be used in switch BC sets and is
therefore forbidden for the complete table.
The problem can be solved only if the (SAP) developer responsible
changes the design of the table/view in the Data Dictionary. The
corresponding field must be replaced by a field that is not of the
'STRING' or 'XSTRING' type. Furthermore, the field must have no more
than 255 characters (output length). If a maintenance dialog was
generated for the table/view, you must then regenerate it by using
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.
