• What is the cause and solution for SAP error message /SMB/COMMON009 - Data conflict, ID &1 already exists in TDC ?

  The SAP error message /SMB/COMMON009 Data conflict, ID &1 already exists in TDC typically indicates that there is a conflict with an identifier (ID) that is already present in the TDC (Transaction Data Container) for the specific application or module you are working with. This error often arises when trying to create or update a record that has a unique constraint on the ID field, and the ID you are trying to use already exists in the system.
  Cause:
  
  Duplicate Entry: The most common cause is that you are attempting to create a new entry with an ID that already exists in the TDC.
  Data Migration Issues: If you are migrating data from another system or performing bulk uploads, there may be duplicate IDs in the data being imported.
  Concurrent Processing: If multiple users or processes are trying to create or update records simultaneously, it may lead to conflicts.
  Incorrect Logic in Custom Code: If there is custom code or enhancements that manipulate IDs, it may inadvertently lead to conflicts.
  
  Solution:
  
  Check Existing Records: Verify if the ID you are trying to use already exists in the TDC. You can do this by querying the TDC table directly or using transaction codes relevant to the module.
  Use a Unique ID: If the ID is already in use, you will need to generate a new, unique ID for the record you are trying to create or update.
  Data Cleanup: If you are migrating data, ensure that there are no duplicates in your source data before importing it into SAP.
  Review Custom Code: If you have custom developments, review the logic to ensure that it correctly handles ID generation and does not create duplicates.
  Locking Mechanisms: Implement proper locking mechanisms if concurrent processing is an issue, to prevent multiple processes from trying to create the same ID at the same time.
  
  Related Information:
  
  Transaction Codes: Depending on the module, you may use specific transaction codes to view or manage records in the TDC.
