List/ListPart inside a CardPage to open another CardPage

Hi,

Our client is using NAV 2017 CU 4. They have a requirement as follows:

The Item card page must show all the pending PO Lines for the item; when a user double-clicks on a line in this list, it should open the respective PO.

Please let me know how to accomplish this.

Thanks in advance.

Regards,
K.P. Sendil Kumar
