• What is the cause and solution for SAP error message FDT_EXPRESSIONS810 - Function call &1 not possible, &2 parameter &3 has a generic type ?

  The SAP error message FDT_EXPRESSIONS810 indicates that there is an issue with a function call in your SAP system where a parameter is expected to have a specific type, but it has been defined as a generic type instead. This typically occurs in the context of using expressions or function modules in SAP's Flexible Data Import (FDI) or similar frameworks.
  Cause:
  
  Generic Type Parameter: The function you are trying to call expects a parameter of a specific type, but the parameter you are passing is of a generic type. This can happen if the function is designed to work with specific data types, and the data being passed does not match those expectations.
  Incorrect Function Usage: The function might be used incorrectly, or the parameters being passed do not align with the function's definition.
  Data Type Mismatch: There may be a mismatch between the expected data type and the actual data type of the variable being passed.
  
  Solution:
  
  Check Function Definition: Review the function module or method definition to understand the expected parameter types. Ensure that the parameters you are passing match the expected types.
  Type Casting: If you are dealing with a generic type, consider explicitly casting the parameter to the required type before passing it to the function.
  Debugging: Use debugging tools in SAP to trace the execution and identify where the parameter is being set. This can help you understand why a generic type is being passed.
  Review Documentation: Consult the SAP documentation for the specific function you are using to ensure you are using it correctly and passing the right types.
  Consult with Developers: If you are not the developer, it may be helpful to consult with the development team to understand the context of the function call and the expected data types.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the function you are using. Sometimes, there are updates or fixes that address specific errors.
  SAP Community: Engage with the SAP Community forums to see if others have encountered the same issue and what solutions they found.
  Testing: Create test cases with different data types to see how the function behaves and to identify the specific conditions that lead to the error.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
