• What is the cause and solution for SAP error message SB128 - Original system of the object not defined in object directory TADIR ?

  The SAP error message SB128 indicates that the original system of the object is not defined in the object directory (TADIR). This typically occurs when you are trying to transport an object (like a program, function module, or other development objects) from one SAP system to another, and the system cannot find the original source system in the transport directory.
  Cause:
  
  Missing Entry in TADIR: The original system from which the object was created is not listed in the TADIR table. This can happen if the object was created in a different system that is not recognized by the current system.
  Transport Directory Issues: There may be issues with the transport directory configuration, or the transport layer may not be set up correctly.
  Object Not Properly Released: The object may not have been properly released for transport, or it may have been deleted or modified in a way that affects its transportability.
  
  Solution:
  
  
  Check TADIR Table: 
  
  Use transaction SE11 to view the TADIR table. Check if the original system of the object is listed. If it is not, you may need to add it manually or ensure that the transport layer is correctly configured.
  
  
  
  Transport Layer Configuration:
  
  Ensure that the transport layer is correctly set up in transaction STMS. You can check the transport routes and make sure that the source system is included in the transport landscape.
  
  
  
  Recreate the Object:
  
  If the object is not critical, consider recreating it in the current system. This can help avoid issues related to missing entries in TADIR.
  
  
  
  Check Transport Requests:
  
  Ensure that the transport request containing the object is correctly released and that there are no issues with the transport request itself.
