Hello again @Govind_Kalburgi. Thx for sharing your intention.
I guess we could do that but the workaround is really not ideal. I’d do it by replicating all the Projects start/end date into new fields for the Global Custom Entity, then, in the detail page you could select and fetch the dates from the fields you want.
1 - In the “Global Dashboard” Custom Entity grid add start/end fields for all Projects:
2 - In the detail page of the Global Burndown Canvas page, setup all the graphs and fields widget using the different project specific start/end
and then you can end up with something like this:
hacky and the down side is that you have to maintain the Projects start/end in the page manually but… still… in the meantime.
