Prepayment process in a Sales Order.
The customer wants to have a discount solution with an extra line (Sales Line type "Charge Item", Field, the field "Unit Price EXcl. VAT is negative e.g. -1 " )
In the prepayment process after entering in the sales header field "prepayment %" e.g. 50 %. You will get the following message "Unit Price must be positive when Prepayment % is not 0. in Sales Line ...."
Is there any possibilities to give a discount (negative line amount) within the Charge Item functions in the prepayment process ?
Many thanks for your responses.
