I am not totally sure what I am doing so I really hope this explanation is succinct 
I am trying to add the requisition number to a Birst report that also has inventory transaction line data. The issue is that inventory transaction line data is not related to requisition data in the Birst model. However, I am hoping that the requisition number is somewhere in the Inventory Transaction Line business class in FSM and I can just add it there for transfer into Birst. I see an 'Originating Document' and am wondering if this might actually be the requisition number (if the system code = Requisition).

If that is not the requisition number and anybody has ideas on how I can get it, please let me know, I am just a Birst girl fumbling around FSM trying to figure out how it works...
Thank you,
Lisa
