3807234 - Modifying an active Cost Component Structure and handling historical splits

• Need to adjust an already active Cost Component Structure (CCS) by activating a new cost component and changing assignments of existing cost elements to cost components.
• Concern that updating the CCS after activation may cause data inconsistency in the cost component breakdown.

SAP S/4HANA Cloud Public Edition

1. Activate a Cost Component Structure (CCS) in a the system.
2. Add a new cost component and change assignments of existing cost elements to cost components.
3. Review the cost component breakdown and observe concerns about potential inconsistencies.

• Historical actual cost component splits are not retroactively adjusted when the CCS is changed; postings remain split according to the CCS that was active at the time of posting.
• Creating an additional/new CCS is not supported in Public Cloud.

1. Do not create a second/new CCS; this is not supported in SAP S/4HANA Cloud Public Edition.
2. Modify the active CCS as needed:
   1. Add new cost components.
   2. Change cost element-to-cost component assignments.
3. Acknowledge that historical actual postings will remain as originally split; the system does not retroactively recalculate historical splits.
4. For future costing and postings, recalculate standard cost estimates for the affected materials, then mark and release them so subsequent transactions follow the updated CCS.
