Are you using Sage 50 Accounting 2019.2? If you are, you can still click on the project to allocate in the G/L as long as the account is set up to allocations with projects. In settings under projects someone may have clicked on the box to allocate using the "Tab" key. In this case you can tab or click on the area for project allocation. I am not sure if this answers your question or not! Please reply!

I'm sorry, maybe i wasn't clear enough.  in the invoice i click on the check mark to allocate - this opens a box to enter the project and the amount to allocate to that project.  in Payable and Receivables I have to click in the space where i enter the project to be able to type anything in that box.  In the G/L using the same process the box to enter the project opens up but I just have to type, not click first.

You have probably hit the tab button or clicked the allocate field which brings you into the project allocation. In the setup settings projects section you may have the box ticked off to use the tab key to go to project allocation field. Otherwise it would skip the allocation if you moved through the journal entry line by line. Hope this helps!

If you wish to allocate from all modules go to Setup/Settings/Projects/Allocations and the bottom box in this window should be checked. This will make it so that the Project Allocations box will be accessed when you tab from the field immediately prior, provided the account is set up to allow project allocations,
