• What is the cause and solution for SAP error message TK891 - Transport layer of target system and target transport layer different ?

  The SAP error message TK891 indicates that there is a mismatch between the transport layer of the target system and the transport layer defined for the target transport layer in the transport request. This typically occurs when you are trying to import a transport request into a system where the transport layer does not match the one that was used when the transport request was created.
  Cause:
  
  Transport Layer Mismatch: The transport request was created in a system with a different transport layer than the one configured in the target system.
