Contains Pattern option

To use the operator "contains pattern" in the selection screen using AFO for Excel, you need to change a parameter setting in your Ao_app.conf file to enable this since it is not enabled by default.

So I opened:

C:\ProgramData\SAP\Cof

Changed the paramter to enable the contains pattern option:

<OperatorContainsPattern value="True"/>

Saved the file and even also restarted the pc. But afterwards the contains pattern option is still not available.

I'm using version 2.2.3.56890. Please advise, many thanks in advance.
