Hi, As I said There are two tables Inventsum & Inventdim when I add Inventtable in data source and link with Inventsum table that time it show blank report. That's why I'm using display method for fetching the data, it display ItemGroupId but not group wise.
//Below method use to display ItemGroupId display ItemGroupId InventTable () {InventTable InventTable; ; return InventTable::find (InventSum.ItemId).ItemGroupId; } Thank'x Nitin
