This error typically arises when there is an attempt to modify a field that is not allowed to be changed during the execution of the BAdI implementation.
  Cause:
  
  Field Restrictions: The field you are trying to change is likely defined as read-only in the context of the BAdI implementation. This means that the system does not permit modifications to this field during the processing of the payment document.
  BAdI Implementation Logic: The logic within the BAdI implementation may not be designed to handle changes to certain fields, either due to business rules or system constraints.

  Review BAdI Implementation: Check the implementation of the BAdI FIBL_OPAY_POST to understand which fields are intended to be modified and which are not. Ensure that your code does not attempt to change fields that are restricted.

  Consult Documentation: Refer to the SAP documentation for the BAdI to understand the intended use and limitations. This can provide insights into which fields can be modified and under what conditions.
  Debugging: If necessary, use debugging tools to trace the execution of the BAdI and identify where the error is triggered. This can help pinpoint the exact line of code or condition causing the issue.
