Offline Load Order Origin

Hello Group:

We are needing to process some offline COM orders as a group, so that the 
offline process does not try to process some other orders that may be 
being built from another application.  I have read some prior posts on 
order origin & think this may be a solution, but need some clarification 
from those using it. 

It seems that if we code the orders we want to process as a group with an 
order origin of '7', we could call the offline process to only look at 
those orders.  Is that logic correct or am I missing something?  Does it 
have to be a '7' or blank - could we make this unique, so that we can 
process a single order at a time by coding a unique value into the order 
origin field?

TIA
