Issue with viewing PO # in Supplier ledger inquiry after Voucher Match

Hi,

I have a question around 3 way voucher match. When matching voucher to PO - we used a 6 digit number (i.e. 121432), once matched and searched for in the Supplier ledger inquiry, it defaults with 00 in front (i.e. 00121432). Thus when searching 121432 in the inquiry - search does not work. Any suggestions why these 2 zeros are getting appended and if there is a way to change that? Thank you.
