• What is the cause and solution for SAP error message TAN_TCC1155 - Master data already exists for DCS ID &1, MIC &2, and curve type &3 ?

  The SAP error message TAN_TCC1155 indicates that there is an attempt to create or modify master data for a specific DCS (Data Collection System) ID, MIC (Measurement Instruction Code), and curve type that already exists in the system. This error typically arises in the context of Quality Management (QM) or similar modules where master data is managed.
  Cause:
  The error occurs when:
  
  You are trying to create a new entry in the master data table for a combination of DCS ID, MIC, and curve type that already exists.
  There may be a duplicate entry in the database that violates the uniqueness constraint for that combination.
  The data being imported or uploaded may contain duplicates.
  
  Solution:
  To resolve the TAN_TCC1155 error, you can take the following steps:
  
  
  Check Existing Data:
  
  Use transaction codes like SE16 or SE11 to view the relevant database table (e.g., TCC or similar) and check if the combination of DCS ID, MIC, and curve type already exists.
  If it does exist, you may need to update the existing record instead of creating a new one.
  
  
  
  Modify or Delete Existing Records:
  
  If the existing record is incorrect or needs to be updated, you can modify it using the appropriate transaction (e.g., QA32 for inspection lots, or the relevant transaction for master data).
  If the existing record is no longer needed, you can delete it, but ensure that this action does not affect other processes.
  
  
  
  Data Import/Upload:
  
  If you are importing data (e.g., via LSMW, BAPIs, or other data upload methods), ensure that the data being uploaded does not contain duplicates.
  You may need to preprocess the data to remove duplicates before the upload.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to the specific module you are working with to understand the constraints and requirements for master data.
  
  
  
  Contact Support:
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
  
  
  
  Related Information:

  Error Logs: Check system logs for additional error messages or warnings that may provide more context about the issue.
