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

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