  Review Configuration: Check the configuration settings in the APO system to ensure that changes to procurement relationships are allowed. This may involve consulting with your SAP Basis or configuration team.
  Check Dependencies: Review any dependencies that may exist for the procurement relationship. This includes checking for any dependent planning objects or transactions that may be affected by the change.
  Authorization Check: Ensure that the user attempting to make the change has the necessary authorizations. If not, contact your system administrator to obtain the required permissions.
