What causes this issue?

You have specified that the <ZK>actual cost component split</> is
<ZK>active</> for one or more valuation areas. After you activate the

create that data for the actual cost component split in the production
system. This ensures that your valuation data is consistent.

actual cost component split to active.
2. Save your Customizing settings.

This feature allows for a more detailed analysis of costs by breaking them down into different components.
  Cause:
  
  Activation of ACCS: The error usually arises when the Actual Cost Component Split has been activated in the system, but the necessary conversion of existing data has not been performed.

  Solution:
  
  
  Data Conversion: You need to perform the data conversion for the existing data. This can typically be done using the transaction code KKS1 (for actual data) or KKS2 (for plan data). This process will convert the existing cost data to the new structure that includes the cost component split.
  
  Go to transaction KKS1 or KKS2.
  Follow the prompts to execute the conversion.
  Ensure that you have the necessary authorizations to perform this action.
