• What is the cause and solution for SAP error message MDG_ID_MATCH_API_BS017 - Object identifier type &1 passed multiple times ?

  The SAP error message MDG_ID_MATCH_API_BS017 indicates that there is an issue with the object identifier type being passed multiple times in a request. This typically occurs in the context of Master Data Governance (MDG) when there are duplicate entries for the same identifier type in the data being processed.
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Duplicate Entries: The same object identifier type is included multiple times in the request payload. For example, if you are trying to create or update a master data record, and you inadvertently include the same identifier (like a business partner ID or material number) more than once.
  Incorrect Mapping: There may be an issue with how the identifiers are mapped in the data model, leading to the same identifier being processed multiple times.
  Data Integrity Issues: There could be underlying data integrity issues in the source data that lead to duplicates being generated.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Request Payload: Review the data being sent in the request to ensure that each object identifier type is included only once. Remove any duplicates.
  
  
  Validate Data Mapping: Ensure that the mapping of identifiers in your data model is correct and that there are no misconfigurations that could lead to duplicates.
  
  
  Data Cleansing: If the data is coming from an external source, perform data cleansing to eliminate duplicates before sending the data to the MDG system.
  
  
  Debugging: If you have access to the backend, you can debug the process to see how the identifiers are being processed and identify where the duplication is occurring.
  
  
  Consult Documentation: Refer to the SAP documentation for MDG to understand the expected structure of the request and the identifiers that should be included.
  
  
  Contact SAP Support: If the issue persists after checking the above points, consider reaching out to SAP support for further assistance, especially if this is a recurring issue.
