• What is the cause and solution for SAP error message W8105 - Container element & is not loop element & ?

  Certainly! Here's a detailed explanation for the SAP error message W8105:
  
  SAP Error Message: W8105
  Message Text:
  
  Container element & is not loop element &
  
  Cause
  This warning message occurs during IDoc processing or EDI (Electronic Data Interchange) when the system expects a certain container element to be part of a loop structure in the IDoc segment hierarchy, but it is not defined as such.
  More specifically:
  
  The IDoc processing logic or the EDI subsystem expects a particular segment (container element) to be within a loop (repeating segment structure).
  However, the segment is not defined as a loop element in the IDoc segment definition or the EDI message type.
  This mismatch causes the system to raise the warning because the processing logic cannot handle the segment as a loop.
  
  
  When does it typically occur?
  
  During inbound or outbound IDoc processing.
  When mapping or converting IDoc segments in EDI subsystems.
  When the segment hierarchy or segment definitions in the IDoc metadata are inconsistent with the actual data or processing logic.
  When custom IDoc segments or extensions are involved and not properly defined as loop elements.
  
  
  Solution
  
  
  Check the IDoc segment definition:
  
  Use transaction WE30 (IDoc Type Development) or WE31 (Segment Editor) to verify the segment definitions.
  Confirm whether the segment in question is defined as a loop element or not.
  
  
  
  Check the IDoc type hierarchy:
  
  Use transaction WE60 (IDoc documentation) or WE82 (Message Type to IDoc Type assignment) to review the segment hierarchy.
  Ensure that the segment is correctly placed inside a loop structure if it is supposed to repeat.
  
  
  
  Adjust the segment definition or processing logic:
  
  If the segment should be a loop element, redefine it as such in the IDoc type.
  If the segment is not supposed to be a loop, adjust the processing logic or mapping to treat it as a single occurrence.
  
  
  
  Check the EDI subsystem or mapping:
  
  If the error occurs during EDI processing, verify the mapping rules in transaction WE20 (Partner Profiles) or the EDI mapping tools.
  Ensure that the segment is handled correctly according to its loop status.
  
  
  
  Regenerate or re-import the IDoc type if changes are made:
  
  After changes, regenerate the IDoc type and transport the changes if necessary.
  
  
  
  Consult SAP Notes:
  
  Sometimes, specific SAP Notes address issues related to IDoc segment definitions and loop handling.
  
  
  
  
  Additional Information
  
  Message Class: W8 (EDI subsystem messages)
  Message Number: 105
  This is a warning message, not an error, so processing might continue but with potential data handling issues.
  Proper segment hierarchy and loop definitions are critical for correct IDoc processing and EDI communication.
  If you are working with custom IDoc extensions, always ensure that the segment definitions and loop structures are consistent with the business requirements and SAP standards.
  
  
  Summary
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Segment expected as loop element but not defined as loop in IDoc structure.
  
  
  Effect
  Warning during IDoc/EDI processing; potential data handling issues.
  
  
  Solution
  Verify and correct segment loop definitions in IDoc type; adjust processing logic or mapping accordingly.
