KI cost center
Cost center does not exist on posting date
Posting fails because the entered or derived cost center is not valid on the document posting date.
Likely root causes
- The cost center validity period does not cover the posting date.
- The wrong controlling area or cost center was derived.
- An old cost center remains in master data, user defaults or interface mapping.
What to inspect
- Posting date, controlling area and cost center.
- KS03 — validity dates and master data.
- Substitution/default/interface logic that supplied the cost center.
Resolution path
- Use the correct active cost center if the assignment is wrong.
- If the business requires the same cost center, have CO master-data owners review its validity.
- Correct stale defaults or mappings.
- Retest with the original posting date.
