Passing data from existing tab to Custom tab using FPM_OIF_COMPONENT

Hi Experts,

Using FPM, I have developed WDA application and assigned to Component FPM_OIF_COMPONENT. Created Application Configuration and Component Configuration. Finally, added this Custom WDA to portal in a new tab. But, the data on this custom WDA UI should come based on the Key field (Project ID) which is present on the existing (Standard ) tab. Can you please help me out as how to fetch this KEY field on the custom WDA to fill other related data.

Thanks and Regards,

Sumesh
