External Bank Reconciliation

Hello

I am trying to use the external Bank reconciliation in SAP Business One 2007.

I want to import the bank statement from my bank to the: Process External Bank Statement window. I will develop a special add-on.

But the question is, i have around 1000 records per account daily, is there any limitation in this window???

Or how i can clean everything from that window, after it has been reconciled??

Thanks

Jacobo
