Does 1099 Processing in PS AP consider Vendor or Vendor Location?

Hello All,

We recently implemented AP(v9.1) for my client who are preparing to process 1099 for the current year.  I have fundamental question regarding this.

As part of conversion, we had to identify vendor location as the source in categorizing 1099 because of different Tax ID they represented but were under one Vendor ID. I am preparing to run delivered process for 1099 and notice PeopleSoft consolidates the transactions at Vendor Level before loading into COPY B table. Is that the way PeopleSoft designed the process? If not, is there a configuration that we missed doing 1099 at vendor location level? The reason I ask this is that PeopleSoft does let you capture details at location level hence my question. I would appreciate if anyone
