• What is the cause and solution for SAP error message FKK_EBS151 - Line &1 of IDoc &2 has an unexpected segment name ?

  The SAP error message FKK_EBS151 indicates that there is an issue with the structure of an IDoc (Intermediate Document) being processed in the context of Electronic Bank Statement (EBS) processing. Specifically, the error states that line &1 of IDoc &2 has an unexpected segment name, which means that the IDoc contains a segment that is not recognized or expected by the system.
  Cause:
  
  Incorrect IDoc Structure: The IDoc being processed does not conform to the expected structure defined in the SAP system. This could be due to a mismatch between the IDoc type and the data being sent.
  Version Mismatch: The IDoc version being used may not match the version expected by the SAP system. This can happen if the sender and receiver systems are not aligned in terms of IDoc definitions.
  Custom Modifications: If there have been custom modifications to the IDoc structure or if custom segments have been added, the system may not recognize these segments if they are not properly defined in the target system.
  Data Corruption: The IDoc data may be corrupted or improperly formatted, leading to unexpected segment names.
  
  Solution:
  
  Check IDoc Structure: Verify that the IDoc structure matches the expected format in the SAP system. You can use transaction WE60 to view the IDoc documentation and ensure that the segments are defined correctly.
  Validate IDoc Type: Ensure that the IDoc type being sent matches the type expected by the receiving system. This can be checked in transaction WE30.
  Review Customizations: If there are custom segments or modifications, ensure that they are properly defined in the target system. You may need to transport the relevant changes or update the IDoc definitions.
  Check for Version Compatibility: Ensure that both the sending and receiving systems are using compatible versions of the IDoc. If necessary, update the IDoc definitions in the receiving system.
  Test with Sample Data: If possible, test the IDoc processing with sample data that is known to be valid. This can help isolate whether the issue is with the specific IDoc being processed or a broader configuration issue.
  Use IDoc Monitoring Tools: Utilize transaction WE02 or WE05 to monitor IDocs and check for any additional error messages or details that can provide more context about the issue.
