  The SAP error message /SCMTMS/TRQ790 &2 not possible for &1; at least one cargo subitem already exists typically occurs in the context of SAP Transportation Management (TM). This error indicates that an operation you are trying to perform (like deleting or modifying a transportation request or a related object) cannot be completed because there is at least one cargo subitem associated with the main item you are trying to modify.
