• What is the cause and solution for SAP error message MDG_ID_MATCH_API_BS021 - ID value &1 contains delimiter of key structure ?

  The SAP error message MDG_ID_MATCH_API_BS021 indicates that there is an issue with the ID value being processed in the Master Data Governance (MDG) system. Specifically, the error states that the ID value contains a delimiter that is part of the key structure, which is not allowed.
  Cause:
  The error typically arises when the ID value being used in a transaction or API call contains characters that are defined as delimiters in the key structure of the relevant data model. In SAP MDG, certain characters (like slashes, commas, etc.) are reserved for separating different parts of a key, and their presence in an ID value can lead to confusion or misinterpretation of the data.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the ID Value: Check the ID value that is causing the error. This will usually be indicated in the error message as &1.
  
  
  Check for Delimiters: Review the ID value for any characters that are defined as delimiters in the key structure. Common delimiters include:
  
  Commas (,)
  Slashes (/)
  Semicolons (;)
  Other special characters
  
  
  
  Modify the ID Value: If you find any delimiters in the ID value, you will need to modify it to remove or replace those characters. Ensure that the new ID value adheres to the expected format and does not include any reserved characters.
  
  
  Test the Changes: After modifying the ID value, re-attempt the operation that triggered the error to see if it resolves the issue.
  
  
  Consult Documentation: If you are unsure about which characters are considered delimiters for your specific data model, refer to the SAP MDG documentation or the data model configuration in your system.
  
  
  Check Configuration: If the issue persists, it may be worth checking the configuration of the data model in MDG to ensure that the key structure is correctly defined and that there are no inconsistencies.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or updates related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  MDG Data Model: Familiarize yourself with the specific data model you are working with in MDG, as different models may have different rules regarding ID formats and delimiters.
  Error Handling: Implement error handling in your API calls or transactions to catch and log such errors for easier troubleshooting in the future.
  
  By following these steps, you should be able to resolve the MDG_ID_MATCH_API_BS021 error and successfully process the ID value in your SAP MDG system.
