Using Batch Service in Pending Vendor Invoice

Hello,

I'm looking to use the batch service job to post pending vendor invoices on the batch server. I know this is possible in AX7 or D365 as I've tested the Pending Invoice batch job in these environments but don't seem to have any luck on the clients AX2012 environment or a Vanilla Contoso AX2012 environment. The batch job isn't queued and the selected pending invoices aren't posted on the batch server.

I've looked at a previous question that has been posted here: https://community.dynamics.com/ax/f/33/t/213800

Unfortunately this is for AX7. Can you please provide some guidance on why the batch service won't work as expected?

Thank you,

Hassan
