purchasing signature authority

does anybody use the bpcs purchase order signature limit capability? our 
impression is that if you set signature authority limits, bpcs will not print a 
PO until it has been approved by a person that has the required authorization 
level? the po can still be created, it just can't be printed. once it is 
approved and printed, is there any indication on the PO itself that it has been 
approved by a person with the proper authorization level and who approved it?

if we were to implement this i know that there is a report that we must run 
that shows all PO's needing to be reviewed and approved. are there any other 
things to watch out for?

we're on bpcs version 6.04
