Sage Web API - ARInvoiceBatches (How to assigned the current Batch Number without create a new Batch?)

Hi all,

I try to assigned the current open batch(E.g: 75), that I manually created in Sage, when I called web API ARInvoiceBatches with BatchNumber=75, it still will create an entry inside new batch (E.g: 80) instead of my current open batch (E.g: 75). May I know how to do this?

Many thanks.

Regards,

Jessie
