Cannot add item from sales order to project.
When a quote has been accepted by the customer and converted to a sales order, there is a button called "Add to Project" beside many of the billable items (perhaps all). When I click that button and search for the name of an existing project that is open, for the same customer and the same site and is of the ticket type project, the search returns no results.
In my admittedly limited testing, this is true for all clients, all sales orders, and all projects.
Does anyone know where I should be looking to try and solve this?
