Set Plant based on workitem plant

Hello All,

We are working on SAP MDG-M, we have requirement where the work items are sent to the plant owners. A Plant owner can be assigned to multiple plants.

When the user opens the work item and tries to processes it, the selected plant should be set to the plant in the workitem in the UIBB. Please do let me know how we can achieve this from FPM UIBB perspective.
