• What is the cause and solution for SAP error message /SCWM/RF_EN206 - Entered data is not unique ?

  The SAP error message /SCWM/RF_EN206 Entered data is not unique typically occurs in the context of the SAP Extended Warehouse Management (EWM) system, particularly when using the RF (Radio Frequency) interface for warehouse operations. This error indicates that the data entered (such as a barcode, item number, or location) is not unique within the system, leading to ambiguity in processing the request.
  Causes:
  
  Duplicate Entries: The most common cause is that the data entered corresponds to multiple records in the database. For example, if you scan a barcode that is associated with more than one item or location, the system cannot determine which one to use.
  Configuration Issues: There may be issues with how the system is configured, leading to multiple entries being recognized as valid for the same input.
  Data Integrity Issues: There could be data integrity problems in the database, such as incorrect or duplicate records that have not been cleaned up.
  User Input Error: The user may have entered the data incorrectly, leading to a situation where the input does not match a single unique record.
  
  Solutions:
  
  Check for Duplicates: Verify the data you are entering. If you are scanning a barcode, check if it is associated with multiple items or locations. You can do this by querying the database or using transaction codes in SAP to check for duplicates.
  Correct Input: Ensure that the input data is correct and corresponds to a unique record. If you are entering data manually, double-check for typos or errors.
  Review Configuration: Check the configuration settings in SAP EWM to ensure that the system is set up correctly to handle the data you are entering. This may involve reviewing master data settings or warehouse configuration.
  Data Cleanup: If there are indeed duplicate records in the system, consider performing a data cleanup to remove or consolidate duplicates. This may require assistance from your SAP Basis or data management team.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to the error message and the context in which it occurs.
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support or your internal IT team for further assistance.

  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP EWM that can help you investigate the issue, such as /SCWM/PRDI for displaying inbound deliveries or /SCWM/PRDI for displaying outbound deliveries.
  User Training: Ensure that users are trained on how to properly enter data into the RF interface to minimize input errors.
  System Logs: Check system logs for additional error messages or warnings that may provide more context about the issue.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
