P43101

I can't find any documentation on the P43101 Purchase Order Workbench. We would like to use this to create a "laundry list" of items needed in the warehouse but allow the user to change the suppier(s) associated if they need to change. My base document has the information on how to set up the processing options I can't find anything that tells me how the program works nor can I find a White Paper.

Any help would be appreciated.
