How To Fix S_CUS_IMG_ACTIVITY234 - Table/view &1 contains forbidden data field (&2 > 255 characters)

SAP Error Message - Details

• Message type: E = Error

• Message class: S_CUS_IMG_ACTIVITY - IMG Activity

• Message number: 234

• Message text: Table/view &1 contains forbidden data field (&2 > 255 characters)

What causes this issue?

Switch BC sets: Table/view &V1& contains data fields with a field length
of more than 255 characters.

System Response

You cannot use the table/view in switch BC sets because a table/view can
only be used in switch BC sets if all fields can be included.

How to fix this error?

This is not an incorrectly designed table/view. Principally, a field can
have a length of more than 255 characters. However, because of BC set
technology restrictions, this table/view cannot be used in BC sets.
The problem can be solved only if the (SAP) developer responsible
changes the design of the table/view in the Data Dictionary. The length
must be reduced to a value < 256 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.
