Entering a Sales Invoice via a script.

[Del Miller <..hidden..>]

I am in need of pushing sales invoices into lsmb via a script.  Writing 
the script is not a problem but I need to know the minimum fields 
required to get an invoice in.  I've looked at the oe.pl module (and 
ended up confused at best) and also the 'enter sales invoice' web page 
that lsmb generates... but there's quite a few fields there to play 
with.  I was hoping to get to writing the script rather than spend the 
next couple of weeks guessing at what may work.  Anyone around here have 
such information??

Regards
