On the Commitments tab within Construction, the total PO Amount is shown, not the amount that is solely for that project. As a project manager that wants to analyze commitments for a project, the total of the PO is not what is needed. The commitments for the project is what is needed.
Having the Order Total may be an interesting piece of information to know that items being ordered for the project are included in a larger PO, but a quick glance at the commitments could give an entirely wrong perception.
The project portion of the PO is shown in the Cost Budget and Balances tabs so there is already code that specifies what the project portion is. This could be as easy as adding a column to the detail of the Commitments tab that shows the project portion.
Just making it easier for Project Managers (and avoiding heart attacks)!
