Context: SAP S/4HANA Cloud 2105 ES - Product availability check (PAC). Assuming you need to change the scope of the availability check in SSCUI 101099. Is it a bad idea to change the existing entries for the combination of checking group and rule? If yes, this configuration step appears not categorised for expert configuration.
Do you request expert configuration anyway? i.e.Is a new Z or Y prefix checking group an option in SAP S/4HANA Cloud 2105 ES? The scope is basic ATP (PAC) - not advancedATP,
