  The SAP error message MDG_ID_MATCH_UI_BS029 indicates that there is an issue with the ID matching process in SAP Master Data Governance (MDG). Specifically, the message states that an object with the specified ID value (represented by &3) already exists in the system, which is causing a conflict during the ID assignment or matching process.
  Cause:
  
  
  Duplicate ID: The primary cause of this error is that the ID you are trying to create or modify already exists in the system. This can happen if:
  
  You are trying to create a new master data record with an ID that is already assigned to another record.
  There is a data inconsistency or duplication in the master data records.
  
  
  
  Incorrect Configuration: The ID matching or assignment configuration in the MDG system may not be set up correctly, leading to conflicts during the ID assignment process.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check for Existing Records:
  
  Use transaction codes like SE16 or SE11 to check the relevant database tables for existing records with the ID in question. This will help you confirm whether the ID is indeed already in use.
  
  
  
  Modify the ID:
  
  If the ID is already in use, you will need to either choose a different ID for the new record or update the existing record if applicable.
  
  
  
  Review ID Assignment Configuration:
  
  Check the configuration settings for ID assignment in the MDG system. Ensure that the ID generation logic is correctly set up to avoid conflicts.
  
  
  
  Data Cleansing:
  
  If there are duplicates in the master data, consider performing data cleansing to remove or merge duplicate records.
  
  
  
  Consult Documentation:
