This error indicates that there is an attempt to make changes to a cost component structure that is currently active, which is not permitted in SAP.
  Cause:

  Navigate to the configuration path: SPRO > Controlling > Cost Element Accounting > Master Data > Cost Component Structure.
  Find the relevant cost component structure and deactivate it.
