• What is the cause and solution for SAP error message FDT_CORE049 - Complex comparisons combined with unique identifiers may cause problems ?

  The SAP error message FDT_CORE049 indicates that there is a potential issue with complex comparisons that involve unique identifiers in your data processing or configuration. This error typically arises in the context of SAP's Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework, which is used for data handling and transformation.
  Cause:
  The error is triggered when the system detects that complex comparisons (like those involving multiple fields or conditions) are being combined with unique identifiers (such as primary keys or unique constraints). This can lead to ambiguous results or unexpected behavior, especially if the unique identifiers do not align with the conditions of the complex comparison.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review the Data Model: Check the data model and ensure that the unique identifiers are correctly defined and used. Make sure that they are not being combined with complex comparisons in a way that could lead to ambiguity.
  
  
  Simplify Comparisons: If possible, simplify the comparisons by breaking them down into simpler conditions. Avoid using multiple fields in a single comparison if they are combined with unique identifiers.
  
  
  Adjust Logic: Modify the logic in your data processing or transformation to ensure that unique identifiers are used appropriately. This may involve restructuring your queries or data mappings.
  
  
  Testing: After making changes, thoroughly test the data processing to ensure that the error no longer occurs and that the results are as expected.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to your version of SAP and the context in which the error occurs.
