• What is the cause and solution for SAP error message FDT_EXPRESSIONS040 - Only single comparisons allowed for test parameter &1 ?

  The SAP error message FDT_EXPRESSIONS040 indicates that there is an issue with the way a test parameter is being used in an expression within the SAP system, specifically in the context of the Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework. The error message states that only single comparisons are allowed for the specified test parameter.
  Cause:
  This error typically occurs when:
  
  You are trying to use a test parameter in a way that involves multiple comparisons (e.g., using logical operators like AND/OR) instead of a single comparison.
  The expression syntax is incorrect, or the logic is not supported by the FDT framework.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Expression: Check the expression where the test parameter is being used. Ensure that it only contains a single comparison. For example, instead of using:
  test_parameter = value1 OR test_parameter = value2
  You should use separate expressions for each comparison.
  
  
  Modify the Logic: If you need to check multiple values, consider restructuring your logic. You might need to create separate conditions or use a different approach to achieve the desired outcome without violating the single comparison rule.
  
  
  Consult Documentation: Refer to the SAP documentation for the FDT framework to understand the limitations and correct usage of test parameters and expressions.
  
  
  Testing: After making the necessary changes, test the expression again to ensure that the error is resolved.
