• What is the cause and solution for SAP error message /SCWM/CCHECK271 - TUs with identical number (TU_NUM_EXT: &1) and carrier &2 exist ?

  The SAP error message /SCWM/CCHECK271 indicates that there are Transport Units (TUs) with identical numbers in the system, which is causing a conflict. This error typically arises in the Extended Warehouse Management (EWM) module when trying to process or manage transport units that have the same external number (TU_NUM_EXT) and are associated with the same carrier.
  Cause:
  
  
  Duplicate Transport Units: The primary cause of this error is the existence of multiple transport units that share the same external number (TU_NUM_EXT) and are linked to the same carrier (&2). This can happen due to data entry errors, system integration issues, or incorrect handling of transport units during warehouse operations.
  
  
  Data Integrity Issues: If the system allows the creation of transport units without proper validation, it can lead to duplicates being created inadvertently.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicate TUs:
  
  Use transaction codes like /SCWM/TU or relevant reports to list transport units and identify those with the same external number and carrier.
  Check the details of the transport units to understand why duplicates exist.
  
  
  
  Delete or Merge Duplicates:
  
  If duplicates are found, determine which transport unit is valid and delete or merge the others as necessary. Ensure that you follow your organization's data management policies when doing this.
  
  
  
  Correct Data Entry:
  
  Review the processes for creating transport units to ensure that they include checks for existing transport units with the same external number and carrier. Implement validation rules if necessary.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to transport unit management in EWM for additional guidance on handling duplicates.
