For example Mr.A ordered 3 things Apple, Banana and Mango. So currently Mr.A is filling the form 3 times for specific products.
But I want to create a prefilled form which fetch the last entry of form like at first Mr.A filled - Sales order id (2323), Product (Banana), Qty(2), Price (Rs.10) then when he saved it and opened the form again the last entered values were automatically prefilled and now he just need to change product, qty and price.
I have tried this with 2 different sheet like Sales Order and Sales Order Details but due to some circumstances I have to do it in one sheet.
