SAP Error Message - Details

• Message type: E = Error

• Message class: SV - View Maintenance: Customize Messages

• Message number: 540

• Message text: Invalid compare flag value '&'

What causes this issue?

The view cluster compare flag is "&V1&", but at least one of the
view/table maintenance dialogs has weaker compare support.

System Response

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

How to fix this error?

Set the compare flag in the view cluster header entry appropriately,
using the possible entries function (F4).
The table/view with the weakest compare support determines the
comparability of the view cluster. If a view is "not comparable", the
entire view cluster is "not comparable "; if a view is only "comparable
in dialog", the view cluster is at most "comparable in dialog".
The comparability criteria for modified view and view cluster dialogs
are in the help for the transaction "Generate table maintenance dialog"
(SE54).
