How to change Sales Type while adding invoice

Hi,

While adding invoice i want to add delivery charges for invoice?
for that i want to change the sales type, so how can i do so?

Thanks for the reply

Yes i am using API

What about the other fields Quantity, Description, Rate, VAT and VAT Amount.
and Will it work with same invoice class object and comes under same invoice.

Hello,

Use the InsertInvoiceLine method with the InvoiceID of the invoice you want to add it to. That way, the line can be added to any invoice you choose.

You can use the online docs at http://accountingapi.com/manual.asp to find out how you should refer to particular fields. For example, for InvoiceLine objects: http://accountingapi.com/manual_class_invoiceline.asp

I am using API
Now i am able to add chargetype and all other fields successfully but How can i select the product from the drop down?
Or what should i have to pass through the API while adding invoice so that it will automatically select one product when i am checking the details of that product.
