i hope someone is able to help me in this regard.
is it possible through code to apply a manual line discount on an existing line in POS?
any help would be appreciated.

i have tried programmatically adding a discount item to the sale line item. it seems to work by discounting the item but the VAT/TAX of the transaction does not seem to calculate, which also affects the total of the transaction.
i am adding the discount in the Blank Operations dll with the below code:
LSRetailPosis.Transaction.RetailTransaction retailTrans = posTransaction as LSRetailPosis.Transaction.RetailTransaction; if ((TypeOfTransaction)retailTrans.TransactionType == TypeOfTransaction.Sales) { foreach (var val in retailTrans.SaleItems) { LSRetailPosis.Transaction.Line.Discount.DiscountItem disc; disc = new LSRetailPosis.Transaction.Line.Discount.LineDiscountItem(); disc.Percentage = Convert.ToDecimal(10); val.DiscountLines.AddFirst(disc); val.Comment = "Test Discount "; val.CalculateLine(); } } retailTrans.CalcTotals(); }
has anyone been able to successfully add a discount line to an existing item?
any help would be greatly appreciated.
i have managed to resolve me issue by adding the following line.
this.Application.Services.Tax.CalculateTax(retailTrans);
