• What is the cause and solution for SAP error message /SCWM/LK204 - IDoc segment E1EDT20 with number &1 is missing ?

  The SAP error message /SCWM/LK204 indicates that there is a missing IDoc segment, specifically the segment E1EDT20, which is part of the IDoc structure used in the SAP Extended Warehouse Management (EWM) module. This error typically arises during the processing of IDocs related to logistics and warehouse management.
  Cause:
  The error occurs when the IDoc being processed does not contain the required segment E1EDT20, which is expected for the operation being performed. This can happen due to several reasons:
  
  IDoc Generation Issues: The IDoc may not have been generated correctly, leading to missing segments.
  Mapping Errors: If there are issues in the mapping of data from the source system to the IDoc structure, it may result in missing segments.
  Configuration Issues: Incorrect configuration in the IDoc processing settings or in the EWM system can lead to this error.
  Data Issues: The data being sent may not meet the required criteria, causing the segment to be omitted.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check IDoc Structure: Verify the structure of the IDoc being processed. Use transaction WE02 or WE19 to analyze the IDoc and check if the E1EDT20 segment is indeed missing.
  
  
  Review IDoc Generation: If the IDoc is generated from another system (like an ERP system), check the configuration and logic used to generate the IDoc. Ensure that all required segments are being populated correctly.
  
  
  Mapping Configuration: If you are using middleware or an interface to map data to the IDoc, review the mapping configuration to ensure that the E1EDT20 segment is included and populated with the necessary data.
  
  
  Check for Data Completeness: Ensure that the data being sent to the IDoc is complete and meets all the necessary criteria. Missing or incorrect data can lead to segments being omitted.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to IDoc processing in EWM for any specific requirements regarding the E1EDT20 segment.
  
  
  Debugging: If necessary, you can debug the IDoc processing logic in the SAP system to identify where the segment is being omitted.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance.
  
  
  Related Information:
  
  IDoc Types: Familiarize yourself with the IDoc types used in your EWM implementation, as different IDoc types may have different segment requirements.
  Transaction Codes: Use transaction codes like WE02 (Display IDoc), WE19 (Test IDoc), and WE20 (Partner Profiles) for IDoc monitoring and troubleshooting.
  SAP Notes: Search for relevant SAP Notes that may address known issues or provide additional guidance on handling IDoc errors.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
