DAVE_TIME_SCAN_REC_DTL2 function in fast formula

Hi All,

When I try calling this function DAVE_TIME_SCAN_REC_DTL2 in fast formula, I get an error: "either function DAVE_TIME_SCAN_REC_DTL2 doesn't exist or the combination of parameter types doesn't match the statement". Did anyone use this function successfully in "Time Calculation Formulas"?

Here are the steps in calling this function:

(1) Call the function DAVE_TIME_SCAN_SET to get rpt_rs_key. This part of code gave right results and no issue with this

(2) Call the function DAVE_TIME_SCAN_REC_DTL2 to get the details. This part of the code is giving compile errors
