• What is the cause and solution for SAP error message E0073 - EDI: Syntax error in IDoc (too many repetitions of a group) ?

  The SAP error message E0073, which indicates a syntax error in an IDoc due to "too many repetitions of a group," typically arises during the processing of an IDoc (Intermediate Document) in the Electronic Data Interchange (EDI) context. This error suggests that the structure of the IDoc does not conform to the expected format defined in the IDoc type.
  Cause:
  
  IDoc Structure Violation: The IDoc contains a segment that is repeated more times than allowed by the IDoc definition. Each IDoc type has a specific structure that defines how many times certain segments can be repeated.
  Incorrect Mapping: If the mapping between the source data and the IDoc structure is incorrect, it may lead to an excessive number of repetitions of a segment.
  Configuration Issues: There may be issues in the configuration of the IDoc type or the associated message type in the SAP system.
  
  Solution:
  
  Check IDoc Structure: Review the IDoc type definition in transaction WE30 or WE31 to understand the allowed repetitions for the segments. Ensure that the data being sent adheres to this structure.
  Validate Data: Ensure that the data being sent to the IDoc does not exceed the allowed repetitions. This may involve checking the source system or the data transformation process.
  Adjust Mapping: If you are using middleware or a mapping tool, check the mapping logic to ensure that it correctly adheres to the IDoc structure.
  Modify IDoc Configuration: If necessary, you may need to adjust the IDoc configuration to allow for more repetitions, but this should be done with caution and in accordance with business requirements.
  Testing: After making changes, test the IDoc generation and processing to ensure that the error is resolved.
  
  Related Information:
  
  IDoc Types: Each IDoc type has a specific structure defined in the SAP system. You can view the structure and allowed repetitions using transaction WE30.
  Error Logs: Check the error logs in transaction WE02 or WE05 for more details about the IDoc processing and to identify which segment is causing the issue.
  Documentation: Refer to SAP documentation or EDI guidelines for the specific IDoc type you are working with to understand the expected structure and limitations.
  
  By following these steps, you should be able to identify the cause of the E0073 error and implement a solution to resolve it.
