Requisition Loader Oddities

Hello,

I am new to using the Puchasing Req Loader process (PO_REQLOAD), but noticed some odd results when loading requisition data with it.

1. I ran the process as myself (I am not a requester) for a requester that has a default Operating Unit and Department ID set up on their Requester Setup profile. On the Requisition that was created, that requester's DEPTID populated as expected, but the OU did not. Where does the Operating Unit get pulled from to populate on the created Req(s) with PO_REQLOAD? Is there setup needed to get it to pull through?

2. It appears the Buyer that is populated on the Req Line Attributes is pulled from User Preferences of the person running the PO_REQLOAD process. We do not assign buyers by default to our Requesters, but instead prefer it default from the Category's setup of whatever they are requesting. How can this process be updated to reference the Buyer established in the ITM_CAT_TBL instead of trying to pull from the User Preferences?
