In configuring the TMS (Transport Management System) QA Approval procedure for an AS ABAP-based system landscape, there are pre-defined approval steps available to ensure quality and compliance of transports. These include approval by the request owner (C), which ensures that the individual who created or is responsible for the transport request approves its movement to the next system; approval by the department (D), which may involve a review by a specific organizational unit or team; and approval by system administration (E), ensuring that the system administrators have verified the technical suitability and impact of the transport. Approval by the developer (A) or project manager (B) are not standard predefined steps in the TMS QA Approval procedure, although organizations may customize their processes to include such approvals.
