[ic] Verify commercial ship to address

[Peter - IC]

Hello,

I want to verify that a customer has a valid address that qualifies for 
UPS Ground Commercial shipping (as opposed to UPS Ground Residential).  
In other words, if they haven't entered a company name, they must take 
UPS Ground Residential.  What's the best way to do this in Interchange? 
  I could do some JavaScripting, but if there's a built in way to do it 
with ITL, I'd rather do that.

Thanks,

Peter
