I Have a cursor such as Split c(1),Batch c(10), Product c(5),Qty n(7,2),

In Grid :

Split Item no. Batch Product Qty
1 A1 A 5
2 A2 B 6
3 A3 C 7

Then I have button Called Split
When Click on Button split at line 1 (Product A), I want to insert a duplicate record into the second line. It depends on how many time I click on Split button.

Such as :

Split Item no. Batch Product Qty
1 A1 A 5
2 A1 A 5
3 A2 B 6
4 A3 C 7

Is that possible to do the sorting like this> any suggestion? Thanks
