Dear all, I am in the middle of importing Invoice details from Excel. By using Collection object i fetched all the records in master Collection. Now i want to group those master records based on the Invoice no. Please advice me what i should use? Group by or filter?. Please share that bit of code for the following Source object Master collection [Object: Mater Sales Object] InvNo : $_2 InvDt : $_3 PartyName : $_4 State : $_5 HSNCode : $_6 Rate : $_7 Qty : $_8 GST % : $_9 Amount : $_10 Tax Amount : $_11 Total:$_12 And for each distinct Invoice no in the master collection, i want the following child collection [Object: Child Sales Object] InvNo : $_2 InvDt : $_3 Rate : $_7 Qty : $_8 GST % : $_9 Amount : $_10 Tax Amount : $_11 Total:$_12 Please elp Regards Karthik
