Limitation of 300 invoices in Accept/Reject file

[Jim Gordon <jgordon@xxxxxxxxxx>]

We have several vendors that send us invoice files electronically and with
that number gradually increasing we are having to deal with the limitation
of 300 invoices in the Accept/Reject file much more often than in the past.
 III tells me that this number cannot be increased.  

I was wondering if other libraries routinely run up against this limitation
and how you manage the workflow.  At times we have to delay loading files,
sometimes for days, until the receiving staff can get caught up.  

Would other libraries like to see the A/R limit expanded?  

Thanks,
