  The SAP error message E0077, which indicates a syntax error in an IDoc (Intermediate Document) with the specific note that the hierarchy level is invalid, typically arises during the processing of EDI (Electronic Data Interchange) messages. This error suggests that there is an issue with the structure or format of the IDoc being processed.
  Cause:
  
  Invalid Hierarchy Level: The IDoc may have an incorrect hierarchy level, meaning that the segments are not properly nested or ordered according to the expected structure.
  Missing Segments: Required segments may be missing, leading to an invalid structure.
  Incorrect Segment Usage: Segments may be used inappropriately or in the wrong context.
  Data Format Issues: The data within the segments may not conform to the expected format or data type.
  Configuration Issues: There may be issues with the IDoc type or message type configuration in the SAP system.
  
  Solution:
  
  Check IDoc Structure: Review the IDoc structure against the expected format. Use transaction WE60 to display the IDoc documentation and ensure that the segments are correctly nested.
  Validate Segments: Ensure that all required segments are present and that they are in the correct order. Check for any optional segments that may be incorrectly included or excluded.
  Review Data: Validate the data within the segments to ensure it adheres to the expected formats and data types. Look for any special characters or invalid data that may cause parsing issues.
  Use IDoc Monitoring Tools: Utilize transaction WE02 or WE05 to monitor IDocs and identify the specific IDoc that is causing the error. This can provide more context on the issue.
  Check Configuration: Review the configuration settings for the IDoc type and message type in transaction WE20. Ensure that the partner profiles are correctly set up and that the mappings are accurate.
  Test with Sample Data: If possible, test the IDoc with sample data that is known to be valid to see if the error persists.
