Field List Extension for Listing / Exclusion

Dear All,

I would like to use further fields for Listing and Exclusion within the SAP S/4HANA Public Cloud.

If I try to enter the table within SSCUI 103214 - Maintain Condition Tables for Listing/Exclusion I got the following Error Message: "You do not have maintenance authorization for usage G application V."

I have all authorizations within the system and I am not able to find any information about this topic.

I would like to use the field "KNA1-KATR8" within this functionality.

Do you have any idea how I can get this field available für Listing and Exclusion?

Thank you in advance!

Kind regards,

Jonas
