How we can call our EAM developed page and return back to Work Order Detail page

Hello,

we would like to add some link to our developed page directly from work order detail page, we will send also variables like &WipEntityId={@WipEntityId}&OrgId={@OrganizationId} that we know in this page. How we can correctly return back to this opened WO detail from our developed OAF page? Does Oracle stores in some variable actual and previous page?

Our solution works fine now till I return from our developed page and do something else in this work order (open PO detail or something else)...

Now we added link to WO detail page:

OA.jsp?page=/oracle/apps/xxon/oafcplauncherparametrized/webui/XXONReportsPG&CP=XXON_SERVICE_CONFIRMATION_FORM&APPLN=XXON&BPURL="/oracle/apps/eam/toolbelt/webui/WorkOrderDetailsPG"
