3543728 - Error "Invalid namespace for Sequence number" in "Define Rules for Advanced Foreign Currency" in SAP S/4HANA Cloud Public Edition

While performing SSCUI-105450 "Define Rules for Advanced Foreign Currency" under valuation rule "SKDV" and Valuation Rule Step "0010", the system triggers the error: "Invalid namespace for Sequence number".

SAP S/4HANA Cloud Public Edition

1. Attempt to configure "Define Rules for Advanced Foreign Currency" under valuation rule "SKDV", Valuation Rule Step "0010".
2. Try to save the "Assign Semantic Tag to FCV Rule".
3. Encounter the error message "Invalid namespace for Sequence number".

It appears that an issue is occurring when creating a new entry in valuation rule step 0010, delivered by SAP which may be caused by a namespace check. This check prevents the creation of new entries if a semantic tag associated with an existing entry has been deleted.

Note: Do not alter the pre-delivered rule step SKDV,0010 during customising activities

To resolve this, follow these steps:

1. Copy the valuation rule delivered by SAP to a customer-specific rule.
2. After copying, update the valuation rule step numbers to fall within your custom namespace.

This approach should allow for unrestricted management of semantic tags. The benefit of using a custom rule is that it ensures many consistency checks are performed during configuration, helping to prevent errors caused by inconsistencies during later processes.
