What is the best method to import from one table (master detail) to another table(master detail) also while in add page. Specific example is Sales order. it has 2 table master detail (20 details) and while in the invoice, I can dropdown the list of sales order and autofill the sales order (master record) but for the detail , i tried to use to programmatically controll the inline add, but if its 20 record or 50 records, it takes so long to auto inline add and populate ever line from sales order details, what is the suggestion?
