I am a beginner with Dynamics GP. I have worked with somewhat similar systems before but they were still different. I have learned quite a bit about the tables and can pull the information I need but am having some trouble editing an invoice. As a staffing service, we bill hours but I cannot find a way to create a line that totals the hours and multiplies by a surcharge. This would just be an additional line in the purchase order. From what I understand, it can be done in Report Writer but I just have not gotten to the point where I can do this. Any help would be greatly appreciated!!!
