The SAP error message KO178, which states "There are no overhead keys for costing sheet &," typically occurs in the context of product costing and cost planning in SAP. This error indicates that the system cannot find any overhead keys associated with the specified costing sheet, which is necessary for calculating overhead costs in product costing.
Cause:
- Missing Overhead Keys: The primary cause of this error is that there are no overhead keys defined for the costing sheet you are trying to use. Overhead keys are essential for determining how overhead costs are allocated to cost objects.
- Incorrect Configuration: The costing sheet may not be properly configured in the system, or the overhead keys may not have been assigned to the costing sheet.

Solution:
To resolve the KO178 error, you can follow these steps:
Check Overhead Keys:
- Go to the transaction code OKTZ (Costing Sheet) in SAP.

Define Overhead Keys:
- If overhead keys are missing, you can define them using transaction code OKT2 (Define Overhead Keys).
- Ensure that the overhead keys are correctly configured with the appropriate parameters.
Assign Overhead Keys to Costing Sheet:
- After defining the overhead keys, ensure they are assigned to the relevant costing sheet using transaction code OKTZ.
- Make sure that the costing sheet is correctly linked to the relevant cost objects.
Check Costing Variant:
- Ensure that the costing variant being used is correctly set up to utilize the costing sheet and overhead keys.
Test the Configuration:
- After making the necessary changes, perform a test run of the costing process to ensure that the error is resolved.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
