3440370 - MLCCS009 error during order settlement (Event-based)

Error found in app Manage Event-Based Posting Errors - Product Costing:
MLCCS009 Internal error in LCL_ACTIVITY_COST_SETTLEMENT method CHECK_AND_RESCALE position 3 with RC

SAP S/4HANA Cloud Public Edition

In the 2502 upgrade, we've introduced a new enhanced check to ensure accurate mapping between FI and Actual Costing tables.
However, the current logic has some defects; for example, it does not exclude already settled documents during a second settlement.

We will temporarily rolled back the check with Emergency Patch (which will be delivered in the weekend March 15th). We will reintroduce it once the logic is refined.
For existing orders with issues, please report the case to SAP for adjustments.
As a temporary solution, we will assist you in running a report in the backend system to split the order cost at the S price.
After the workaround, reprocessing in app Manage Product Costing Errors is needed.
