We use both - depending on the situation. If we get an application that's missing a SS number, or something else that's needed to make an initial credit determination, we send an AA notice for incomplete application. If we don't subsequently receive the missing information, it is reported on the LAR as a denial for incomplete application.
If we have enough information to issue a conditional approval, after a certain period of time we issue an incomplete notice for the items that are still missing. If we don't receive those items by the deadline in the notice, the application is reported on the LAR as incomplete.
