  The SAP error message /SCMTMS/TCCS285 Line &1: Cannot add a cost item as a subitem of another cost item typically occurs in the context of SAP Transportation Management (TM) when there is an attempt to create a hierarchical relationship between cost items that is not allowed by the system's configuration or business rules.
  Cause:
  
  Hierarchical Structure Violation: The error indicates that you are trying to add a cost item as a subitem of another cost item, which is not permitted. In SAP TM, certain cost items are not designed to have subitems, or the relationship you are trying to establish is not valid.

  Review Cost Item Structure: Check the configuration of the cost items involved. Ensure that the cost item you are trying to add as a subitem is allowed to be a subitem of the parent cost item.
  Modify Relationships: If the relationship is not valid, consider restructuring your cost items. You may need to create a new cost item that can serve as a subitem or adjust the hierarchy to comply with the rules.
  Consult Documentation: Refer to the SAP documentation or help resources for guidance on the specific cost item configurations and their allowed relationships.
  Check Customizations: If your SAP system has custom developments or enhancements, ensure that they are not interfering with the standard behavior of cost item relationships.
  Testing: After making changes, test the configuration in a development or quality assurance environment before applying it to production.
