  The SAP error message /SMB/TYPES056 TDC &1 cannot be referenced by different TDC Aliases &2 and &3 typically occurs in the context of SAP Business One or SAP Business Technology Platform (BTP) when there is a conflict in the usage of Type Definition Classes (TDCs) and their aliases.
  Cause:
  This error indicates that a specific TDC (Type Definition Class) is being referenced by multiple aliases, which is not allowed. Each TDC should have a unique alias to avoid confusion and ensure that the system can correctly identify and manage the data types.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the TDC and Aliases: Check the TDC mentioned in the error message (&1) and the aliases (&2 and &3) that are causing the conflict. You can usually find this information in the SAP system where the TDCs are defined.
  
  
  Review TDC Definitions: Go to the TDC definitions in your SAP system and review how the TDC and its aliases are set up. Ensure that each TDC has a unique alias.
  
  
  Modify Aliases: If you find that the same TDC is being referenced by different aliases, you will need to modify the aliases to ensure that each TDC is only referenced by one alias. This may involve renaming one of the aliases or creating a new TDC if necessary.
  
  
  Check for Dependencies: If the TDC is being used in other parts of the system (like reports, queries, or integrations), ensure that changing the alias does not break any existing functionality.
  
  
  Test Changes: After making the necessary changes, test the system to ensure that the error no longer occurs and that the TDCs function as expected.
  
  
  Consult Documentation: If you are unsure about how to proceed, refer to the SAP documentation or consult with your SAP administrator or support team for guidance.
