For this example; I am using Projects List page and will add Revenue Info Part on it.
Right click on AOT\Parts\Info Parts and create New Info Part
Assign Query to this info part I have assigned ProjTable_NoFilter query
Add New Group under Layout
Name it ProjectRevenue and set few properties as shown
Note I haven't assigned DataSource to this group, I will be using data methods to get data here.
Add new fields under ProjectRevenue group and name it RevenueAtSales and RevenueAtOrders
Name it FF_ProjectRevenue
Set IsLinked Property to YES, this property will link this part to the list page based on Datasource (ProjTable)
Create new display menu item and name it FF_ProjectRevenueMenuitem
Assign this menu item as Part property in ProjProjectListPage
Time to see this info Part on List page, Open All Projects form and here it goes
