1) Need to create option to allow SOs to remain open after being fully invoiced.

2) Allow manual insertion of a SO number already used in the past.

3) create validation on Timesheets with status submitted or open linked to service order. If the doc is posted with pending time sheet approval the system should at least warn the user. You post this then you have no change of approving open time sheets, really messy.

This will solve the issue of corrections and credits. Serv Orders are more complicated than Sales Orders to correct and credit. FIRSTLY Sales orders allows you to manually insert a Sales Order number used in the past for some reason. If you make a mistake on service order, credit invoices and if you need to generate a new Service Invoice you will need to make a new Service Order number and then delete timesheet lines and point time sheets to new order, if any service report or confirmation was done and signed by technician we will need to redo that paperwork too. Its just a mess. We should be able to keep orders open and then manually close them after an invoice is paid for example, or be able to revive a Service Order form an archive, or at least re-create it, so we dont have to redo underlying work just correct an invoice.
