After doing cheque run, client remembered that there was one vendor to be processed separately as there were previously posted credit memos and invoices to put on that cheque.  If that cheque was voided, would that put the cheque amount back into the amount owing column of the vendor ledger entries, thus allowing me to run a cheque for that vendor, which will pull everything in that amount owing column?


The vendor ledger entries aren't updated until the payments journal is posted. If a cheque is voided in the payments journal, and the line(s) deleted, vendor ledger entries will still be open for this vendor.
