• What is the cause and solution for SAP error message FDT_HANA181 - &2 and &3: The same result view field name &1 occurs twice ?

  The SAP error message FDT_HANA181 indicates that there is a problem with the definition of a result view in a data model, specifically that the same field name is being used more than once in the result view. This can lead to ambiguity when trying to access or manipulate the data, as the system cannot determine which instance of the field to use.
  Cause:
  The error typically arises from one of the following scenarios:
  
  Duplicate Field Names: The same field name is included multiple times in the result view, either from the same data source or from different sources.
  Join Conditions: If you are joining multiple tables or views, and they contain fields with the same name, this can lead to duplication in the result view.
  Field Aliases: If aliases are not used properly, it can result in the same field name being referenced multiple times.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Identify Duplicate Fields: Review the result view definition to identify where the duplicate field names are coming from. Look for fields that are being pulled from different sources or are being included multiple times.
  
  
  Use Aliases: If you need to include the same field from different sources, use aliases to differentiate them. For example, if you have a field named CustomerID from two different tables, you can rename them in the result view as CustomerID_A and CustomerID_B.
  
  
  Remove Duplicates: If the duplicate fields are not necessary, consider removing one of the instances from the result view.
  
  
  Check Joins: If the error is due to joins, ensure that the join conditions are set up correctly and that you are not unintentionally pulling in duplicate fields.
  
  
  Test the Changes: After making the necessary adjustments, test the result view to ensure that the error is resolved and that the data is being returned as expected.

  Debugging Tools: Utilize SAP's debugging tools to trace the data flow and identify where the duplication is occurring.
  
  By following these steps, you should be able to resolve the FDT_HANA181 error and ensure that your result view is correctly defined without duplicate field names.
