My data model is as follows:
I am trying to achieve the following :-
Can anyone help with this please? I am really stuck.

hi, @ainsleybilton
You could try this way:
Step1:
Create a duplicate locations table as targe locations table.
target locations = locations
target site name = LOOKUPVALUE(Sites[Site Name],Sites[ID],'target locations'[ID])Step2:
Kilometers = var Lat1 = MIN('locations'[lat]) var Lng1 = MIN('locations'[lng]) var Lat2 = MIN('target locations'[lat]) var Lng2 = MIN('target locations'[lng]) ---- Algorithm here ----- var P = DIVIDE( PI(), 180 ) var A = 0.5 - COS((Lat2-Lat1) * p)/2 + COS(Lat1 * p) * COS(lat2 * P) * (1-COS((Lng2- Lng1) * p))/2 var final = 12742 * ASIN((SQRT(A))) return finalStep5:
Amount = IF([Kilometers]<=[Distance Value],CALCULATE(COUNTA(employees[Employee Name]),ALL(Sites)))Step6:

As an additional bit of information, I tried using a calculated table to get the distance between the locations as below:
