  The SAP error message LTR_MODEL_APPL081 with the description "Link direction must be set" typically occurs in the context of SAP's Logistics and Transportation Management modules, particularly when dealing with transportation models or planning scenarios.

In transportation planning, links often have a specific direction (e.g., from a source location to a destination location), and if this direction is not specified, the system cannot process the transportation model correctly.
  Solution:
  To resolve this error, you should take the following steps:
  
  
  Check Link Definitions:
  
  Navigate to the transportation model or planning scenario where the error occurred.
  Review the definitions of the links involved. Ensure that each link has a clearly defined direction (e.g., from point A to point B).
  
  
  
  Set Link Direction:
  
  If the link direction is not set, you will need to specify it. This can usually be done in the configuration or setup screen for the transportation model.
  Look for fields or options related to "Link Direction" and ensure they are filled out correctly.
  
  
  
  Validate Configuration:
  
  After setting the link direction, validate the entire transportation model configuration to ensure there are no other missing or incorrect settings.
  
  
  
  Test the Configuration:
  
  Once changes are made, test the transportation model to ensure that the error no longer appears and that the model functions as expected.
  
  
  
  Consult Documentation:
  
  If you are unsure about how to set the link direction or if the error persists, consult the SAP documentation or help resources specific to your version of SAP. This can provide additional context and guidance.
