• What is the cause and solution for SAP error message WES_OUTBOUND054 - Enter a logon/server group for parallel processing ?

  SAP Error Message:
  
  WES_OUTBOUND054 – Enter a logon/server group for parallel processing
  
  Cause:
  This error occurs when you are trying to execute an outbound process (such as IDoc processing or ALE distribution) in parallel mode, but the system does not have a logon group or server group specified for parallel processing. The system requires a logon group/server group to distribute the workload across multiple application servers for parallel processing.
  In other words, the system expects you to specify a logon group or server group to enable parallel processing, but this information is missing or not maintained.
  
  Explanation:
  
  Parallel processing in SAP allows distributing tasks (like IDoc processing) across multiple application servers to improve performance and throughput.
  To enable this, you must define logon groups or server groups in the system.
  When executing outbound processing in parallel, the system needs to know which group of servers to use.
  If this is not specified, the system throws the WES_OUTBOUND054 error.
  
  
  Solution:
  
  
  Maintain Logon Groups:
  
  Go to transaction SM59 (RFC Destinations).
  Check or create RFC destinations with the appropriate logon group.
  Alternatively, maintain logon groups in transaction SMLG.
  Logon groups are logical groups of application servers that users or processes can connect to.
  
  
  
  Specify Logon/Server Group in the Process:
  
  When scheduling or executing the outbound process (e.g., in transaction WE20, WE19, or the relevant outbound processing transaction), specify the logon group or server group for parallel processing.
  This is often a field labeled "Logon Group" or "Server Group" in the selection screen or processing parameters.
  
  
  
  Check Distribution Model and Partner Profiles:
  
  Ensure that the partner profiles and distribution model are correctly configured for parallel processing if applicable.
  
  
  
  If Parallel Processing is Not Needed:
  
  If you do not want to use parallel processing, disable the parallel processing option or leave the logon/server group field blank.
  
  
  
  
  Additional Information:
  
  Transaction SMLG: Used to maintain logon groups.
  Transaction SM51: To check active application servers.
  Transaction SM59: To maintain RFC destinations.
  Parallel Processing: Improves performance by distributing workload but requires proper configuration.
  This error is common in ALE/IDoc outbound processing scenarios where parallel processing is enabled but not fully configured.
  
  
  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  No logon/server group specified for parallel processing during outbound processing.
  
  
  Solution
  Maintain logon/server groups (SMLG), specify them in outbound processing parameters.
  
  
  Related Tcodes
  SMLG (Logon Groups), SM59 (RFC Destinations), WE20 (Partner Profiles), WE19 (Test IDoc)
  
  
  Notes
  Disable parallel processing if not required or ensure proper configuration if enabled.
