• What is the cause and solution for SAP error message FDT_CORE116 - Allowed comparison type &1 does not fit signs, options, or multiple ?

  The SAP error message FDT_CORE116 indicates that there is a mismatch in the comparison types used in a formula or condition within the SAP system, particularly in the context of the Field Data Tool (FDT) or similar functionalities. This error typically arises when the system encounters a comparison that involves incompatible data types or signs.
  Cause:
  
  Data Type Mismatch: The error often occurs when you are trying to compare two fields or values that are of different data types (e.g., comparing a string with a number).
  Sign Mismatch: If one of the values is signed (positive/negative) and the other is unsigned, the comparison may not be valid.
  Multiple Values: If you are trying to compare a single value against a set of multiple values without proper handling, it can lead to this error.
  Incorrect Configuration: The configuration of the fields or the logic defined in the FDT might not be set up correctly, leading to incompatible comparisons.
  
  Solution:
  
  Check Data Types: Ensure that the fields or values being compared are of the same data type. If necessary, convert one of the values to match the other.
  Review Signs: Make sure that the signs of the values being compared are compatible. If one value is signed and the other is not, consider adjusting the logic to handle this appropriately.
  Adjust Logic: If you are using multiple values in a comparison, ensure that you are using the correct syntax and logic to handle those comparisons. For example, use IN for checking if a value exists in a set.
  Debugging: Use debugging tools or logs to trace where the error is occurring. This can help identify the specific comparison that is causing the issue.
  Consult Documentation: Review the SAP documentation related to the Field Data Tool or the specific module you are working with to ensure that you are following best practices for comparisons.
