Using EDI may put me in a small minority, but I guess all I need is an answer.  
 
Is it true that I cannot access the BKEDIH table (to add new records) if someone else is viewing an EDI order?  
 
We used to have trouble many moons ago when two users were trying to work with Sales Orders at the same time. That problem has gone away as far as I know, but it appears to still be a problem in S/R, RMA, and now EDI orders. Are these programs locking the file when they are accessing a record?
