display on a map, all rows from a slice, based on their distance from the current row's LatLong

Hello again!

I have two tables: Current Orders and Past Orders. Both tables have a [Map] column, type LatLong

When I am in the detail view of a Current Order I need an Action which takes me to “another view within the app” which will be a map view, populated by a slice of the Past Orders, filtered by all that are within .5 km of the one Current Order i am viewing.

I basically have it set up without any massive errors, but the map view via the action is not filtered. its showing me all past orders

I can’t figure out how to calculate the distance when the LatLongs are in two different tables - I get an error when I try to point at the other table or slice for location2 in this expression

Distance([location1],[location2]) :

SLICE: (name = “withinhalfkm”)

AND(
ISNOTBLANK([PastOrdersMap]),
(DISTANCE([PastOrdersMap], [_THISROW].[CurrentOrderMap]) < 0.5)
)

Deep Link:

CONCATENATE(“#page=map&table=withinhalfkm&mapcolumn=Map&row=”, ENCODEURL([_THISROW]))

How about using LINKTOFILTEREDVIEW() in navigation action in the “Current Orders” detail view. I believe, this will not need a slice to be created unless slice is also required for some other purpose.

LINKTOFILTEREDVIEW("Past Orders Summary View", DISTANCE([PastOrdersMap]- [_THISROW].[CurrentOrderMap])<=0.5)

Here "Past Orders Summary View" is the summary view that you are already having for “Past Orders” table to display multiple past orders in the app.
