  Review the Structure: Check the structure definition in the Data Dictionary (transaction SE11) to understand which fields are causing the issue. Ensure that you are not trying to manipulate fields that are not meant to be changed.
  Use Appropriate Tools: If you need to change data, consider using appropriate tools or transactions that allow for data manipulation, such as LSMW, BAPIs, or direct updates through ABAP programs, depending on your requirements.
