• What is the cause and solution for SAP error message FDT_HANA159 - &2 and &3: The same source field name &1 is used ?

  The SAP error message FDT_HANA159 typically indicates that there is a conflict in the field names being used in a data transformation or mapping process within SAP's Data Transformation (FDT) framework. Specifically, the error message states that the same source field name is being used multiple times, which can lead to ambiguity in data processing.
  Cause:
  
  
  Duplicate Field Names: The error arises when the same source field name is defined more than once in the context of a transformation or mapping. This can happen if:
  
  You have multiple source structures that contain fields with the same name.
  You are trying to map fields from different sources that have identical names without proper differentiation.
  
  
  
  Incorrect Configuration: The configuration of the data transformation might not be set up correctly, leading to the same field being referenced multiple times.
  
  
  Solution:
  
  
  Rename Fields: Ensure that each source field has a unique name. You can rename the fields in the source structure or during the mapping process to avoid conflicts.
  
  
  Check Mapping Logic: Review the mapping logic to ensure that you are not unintentionally referencing the same field multiple times. If you need to use the same data, consider creating an alias or a derived field.
  
  
  Use Unique Identifiers: If you are working with multiple sources, consider using unique identifiers or prefixes for field names to avoid conflicts.
  
  
  Review Data Sources: If you are pulling data from multiple sources, check the definitions of those sources to ensure that they do not have overlapping field names.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling field names in data transformations.
