AX 2012 warehouse mobile device portal

Hi,

I am facing an issue with warehouse mobile device portal when I am executing PO Putaway process. When I enter the license plate Id and click OK, the details related to the license plate is shown. After that when I click OK to proceed further, nothing happens. This same process works when I open AX form WHSWorkExecute.

Can anybody tell what is the issue?

Thanks,

Surbhi
