3570937 - Error "Select a key from the allowed namespace" when assigning custom date rule to standard date profile - SAP S/4HANA Cloud Public Edition

Error "Select a key from the allowed namespace" occurs when assigning custom date rule (e.g., ZBIL00001) to a standard date profile (e.g., CONT002).

SAP S/4HANA Cloud Public Edition

The root cause lies in that standard date profiles are not allowed to be assigned with custom date rules.

1. Copy the standard date profile to a custom date profile via the configuration activity "Define Date Profile for Service Transactions (ID: 104301)".
2. Do the relevant assignments to this custom date profile.
3. Assign this custom date profile to the service contract type and service contract item categories, via the configuration activities "Assign Date Profile to Transaction Types (ID: 104327)" and "Assign Date Profile to Item Categories in Service (ID: 104328)".
