  The SAP error message /SMB/TYPES003 Duplicate TDC assignment (lines &1 and &2) typically occurs in the context of the SAP Business One or SAP Business ByDesign systems, particularly when dealing with TDC (Time Data Collection) assignments. This error indicates that there are duplicate entries for TDC assignments in the system, which can lead to inconsistencies or conflicts in data processing.
  Cause:
  The error is caused by having two or more entries in the TDC assignment table that reference the same data or configuration. This can happen due to:

  If the duplicates contain unique information that needs to be preserved, consider merging the relevant data into a single entry.
