• What is the cause and solution for SAP error message ICA02024 - Comparator &1 is not allowed for the field &2. ?

  The SAP error message ICA02024 indicates that a specific comparator (like =, >, <, etc.) is not allowed for a particular field in the context of a query or selection criteria. This error typically arises when you are trying to filter or compare data in a way that is not supported by the data type or the field's configuration.
  Cause:
  
  Incompatible Data Types: The comparator you are using may not be compatible with the data type of the field. For example, trying to use a string comparison on a numeric field.
  Field Configuration: The field may have specific restrictions on the types of comparisons that can be made. For instance, certain fields may only allow equality checks.
  Incorrect Query Logic: The logic of the query or selection criteria may be incorrectly formulated, leading to the use of an unsupported comparator.
  
  Solution:
  
  Check Data Types: Verify the data type of the field you are trying to compare. Ensure that the comparator you are using is appropriate for that data type.
  Review Field Documentation: Look into the documentation or configuration of the field to understand what comparators are allowed. This can often be found in the data dictionary (SE11) or through the field's technical details.
  Modify the Query: Adjust your query or selection criteria to use a valid comparator for the field in question. For example, if the field is numeric, ensure you are using numeric comparators.
  Test with Simple Comparators: Start with simple equality checks (=) to see if the error persists, and then gradually introduce more complex logic as needed.
  
  Related Information:
