• What is the cause and solution for SAP error message /SCWM/TM018 - Asynchronous call of function &1 for destination &2 ?

  The SAP error message /SCWM/TM018 indicates an issue with an asynchronous call to a function module in the context of the SAP Extended Warehouse Management (EWM) system. This error typically arises when there is a problem with the communication between the EWM system and the destination system (like an SAP backend system or another service).
  Cause:
  
  
  Destination Configuration Issues: The destination specified in the error message may not be correctly configured in the SAP system. This could include incorrect RFC (Remote Function Call) destination settings or missing entries in the transaction SM59.
  
  
  Network Issues: There may be network connectivity problems between the EWM system and the destination system, preventing successful communication.
  
  
  Authorization Issues: The user or service account used for the asynchronous call may not have the necessary authorizations to execute the function module in the destination system.
  
  
  Function Module Issues: The function module being called may not exist, may be inactive, or may have been changed in a way that it no longer accepts the parameters being passed.
  
  
  System Performance: If the destination system is under heavy load or experiencing performance issues, it may not be able to process the asynchronous call in a timely manner.
  
  
  Solution:
  
  
  Check Destination Configuration:
  
  Go to transaction SM59 and verify the configuration of the RFC destination mentioned in the error message.
  Test the connection to ensure it is working correctly.
  
  
  
  Review Network Connectivity:
  
  Ensure that there are no network issues preventing communication between the systems. This may involve checking firewalls, VPNs, or other network configurations.
  
  
  
  Check Authorizations:
  
  Verify that the user or service account has the necessary authorizations to execute the function module in the destination system.
  
  
  
  Validate Function Module:
  
  Check if the function module being called exists in the destination system and is active. You can do this by using transaction SE37 to look up the function module.
  
  
  
  Monitor System Performance:
  
  Check the performance of the destination system. If it is under heavy load, consider optimizing the system or scheduling the calls during off-peak hours.
  
  
  
  Review Logs:
  
  Check the application logs (transaction SLG1) for more detailed error messages that may provide additional context for the issue.
