On the "Project" tab, if the purchase quotation request document is related to a "Project" or a WBS project document, you can select the project from the "Projects" window and save and send it. If you want to link the WBS of the project, you can do the same.
If you want to associate more projects, select the first one, type "% Rate" and save. The system will show another two-row field for adding more projects and WBS items, and show the remaining % rate to complete to 100%.
To delete project records, you must check the "Delete" checkbox and click the "Delete" button.
