  Solution:
  To resolve this error, you can consider the following steps:

  Use the Correct Transaction: Ensure you are using the appropriate transaction code for editing forecast values. If you are in a transaction that does not allow changes to certain forecast values, switch to the correct transaction.

  Consult Documentation: Refer to SAP documentation or help files related to the specific forecasting module you are using. This can provide insights into the rules governing forecast changes.
