  The SAP error message IDMX160, which states "CFDI approval process already started, field '&1' should not be changed," typically occurs in the context of the CFDI (Comprobante Fiscal Digital por Internet) approval process in SAP. This error indicates that an attempt is being made to modify a field that is not allowed to be changed once the approval process has begun.
  Cause:

  Solution:
  
  Check Approval Status: Verify the status of the CFDI approval process for the document in question. If it is already in progress, you will need to wait until the process is completed before making any changes.
  Avoid Changes During Approval: Ensure that no changes are made to the document once the approval process has started. If changes are necessary, you may need to cancel the approval process (if possible) and then make the required changes before reinitiating the approval.
  Consult Documentation: Review the SAP documentation or configuration settings related to CFDI to understand which fields are restricted during the approval process.
  User Training: Educate users on the importance of not modifying documents once the approval process has started to prevent this error from occurring in the future.
