Unable to view all Purchase Order in list page

Hi Experts,

I have an issue with Ax 2012 Purchase Order list page form in our test environment. It showing only a particular supplier's orders instead on entire order list in the list page. In the table level, we have entire purchase data for all suppliers and that to the latest db backup of production. I don't know why this is happening now even I have restarted the service and cleared my usage data.

Please share your valuable ideas if any to solve this or you done before.

Thanks in Advance!!!!!!!!!!!!!
