Filter Portal Records by portal setup
I enable "Fileter Portal Records" on portal setup by filtering "PO Number" which is a global field. "PO Number" is a pop up menu, refer to B, which I can select PO number. The filter works when I start the system. But the portal filter does not update portal when I select different PO number from the pop up menu. When I restart the system, the new selected PO Number will be on the global field and the portal is filtered by the new PO Number.
How can I force the portal filter activate when I select new PO number?
