Hi All,

I have retrieved the prevData value(numeric value,number) from the form, which was loaded into the DataGridDefinitionBuilder. I am trying to perform a calculation in the Essbase calc script, which requires the variable prevData value. Is there any way I can pass this value (like set value for RTPs) to the RTPs so that I can perform the subtraction calculation? I have tried prevData.data(). Essbase calc script is not taking even though the @return prints the value successfully. Thank you.
