[System:Formulae]
MyFilter:$StName = #StkItemfld

Requested to kindly help me in this regard.

Thanks in Advance

 

Compute:StName:$..StockItemName

Why two Dots.?

 

Jai Sir, I have used two dots to access the Stock Item Name from its Parent object, but its not working, please tell me where is mistake.

 

$Name:Stockitem:$StockItemName

 

Jai Sir, now its filtering item wise detail properly, thank you very much for solution.
