• What is the cause and solution for SAP error message IDOC_ADAPTER120 - IDoc_Adapter: Segment Limitation &1 > &2 ?

  The SAP error message IDOC_ADAPTER120 indicates that there is a segment limitation issue in the IDoc (Intermediate Document) processing. This error typically occurs when the number of segments in an IDoc exceeds the maximum allowed limit defined for that specific IDoc type.
  Cause:
  
  Segment Limit Exceeded: Each IDoc type has a predefined maximum number of segments it can contain. If the IDoc being processed has more segments than this limit, the error will be triggered.
  Incorrect IDoc Structure: The IDoc may have been incorrectly structured or generated, leading to an excessive number of segments.
  Configuration Issues: There may be configuration settings in the IDoc type definition that are not aligned with the data being sent.
  
  Solution:
  
  Check IDoc Structure: Review the IDoc structure and ensure that it adheres to the defined limits. You can do this by checking the IDoc type in transaction WE30 (IDoc Type Development).
  Reduce Segment Count: If possible, modify the data being sent to reduce the number of segments. This may involve consolidating data or splitting it into multiple IDocs if necessary.
  Adjust IDoc Type Definition: If you have control over the IDoc type definition, you may consider increasing the segment limit if it is feasible and aligns with your business requirements. This can be done in transaction WE30.
  Review Mapping Logic: If you are using middleware (like SAP PI/PO), check the mapping logic to ensure that it is not generating unnecessary segments.
  Consult Documentation: Refer to SAP documentation for the specific IDoc type to understand its limitations and structure.
