Dear Team,I am trying to make a partial invoice proposal of project sales order but it is not allowing me to change the quantity on Invoice proposal Form.My client wants to do the partial invoicing of a project sales order and they don't want to add multiple lines on project sales order and select the lines on Invoice proposalIs there any work around to do partial invoicing of project sales order.For Example.I have project sale order of 50 quantity and I want to make an invoice proposal of only 25 quantities and the rest will appear on another Invoice proposal.I have also tried to Pack the sales order item but the generate Invoice option is disable when we select the project in sales order.
