How to enter an adjustment voucher for a large posted voucher?

Hi,

We are on version 9.2 pum 23. (I thought we were on pum 37, but I believe that is the most current and we aren't there yet.)

Vouchers with more than about 300 lines (voucher or distrib) will not pull up under Regular Entry. It times out. We have a BU needing to enter an adjustment voucher for a large voucher that is posted and paid. However, they cannot do it because the voucher times out before it will copy in to do the adjustment. How do they enter the adjustment (other than retyping in all the lines) ?

Please let me know if you need more information.
