• What is the cause and solution for SAP error message FDT_EXPRESSIONS156 - Invalid usage of direct value in condition column &1 (line &2) ?

  The SAP error message FDT_EXPRESSIONS156 indicates that there is an invalid usage of a direct value in a condition column within a specific context, such as a decision table or a similar configuration in SAP. This error typically arises when the system encounters a direct value that is not allowed in the specified condition column.
  Cause:
  
  Direct Value Misuse: The error usually occurs when a direct value (like a constant or literal) is used in a condition column where it is not permitted. This can happen if the condition is expecting a variable or a reference instead of a direct value.
  Incorrect Configuration: The configuration of the decision table or expression might be incorrect, leading to the system not being able to interpret the direct value properly.
  Data Type Mismatch: There may be a mismatch between the expected data type of the condition column and the type of the direct value being used.
  
  Solution:
  
  Review the Condition Column: Check the configuration of the condition column where the error is occurring. Ensure that it is set up to accept direct values if that is your intention.
  Use Variables Instead: If the condition column is not designed to accept direct values, consider using a variable or reference that can be evaluated at runtime instead of a hardcoded value.
  Check Data Types: Ensure that the data type of the direct value matches the expected data type of the condition column. If there is a mismatch, adjust the value or the column configuration accordingly.
  Consult Documentation: Refer to the SAP documentation or help resources related to the specific module or functionality you are working with to understand the correct usage of condition columns and direct values.
