• Message text: Excluding two values can produce incorrect selections

What causes this issue?

In your selection, you chose more than one value with the option
'UNEQUAL'. This can, under certain circumstances, lead to all entries

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?

Use 'EXCLUDE FROM SELECTION' and the '=' option to exclude individual
values from the result.
Example:
Selecting all suppliers except CHARLIE and BILLY:
Option 1: I NE CHARLIE
I NE BILLY
Option 2: E EQ CHARIE
E EQ BILLY
Only option 2 produces the corresct result, since in option 1, the

ALL entries being selected.
