  The SAP error message CRM_COMPL_ARM_CHECK028 indicates that there is an issue with maintaining a vendor for a specific activity in the CRM (Customer Relationship Management) module. This error typically arises when the system expects that certain activities should not have a vendor assigned to them, but a vendor has been specified.
  Cause:

  Review Configuration: If you believe that the activity should allow vendor assignments, check the configuration settings in the CRM system. You may need to consult with your SAP administrator or a functional consultant to adjust the settings accordingly.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on the specific activity type and its requirements regarding vendor assignments.
