Hello all,
I'm trying to write a measure to calculate distance between two lat/long pairs. The measure works as expected when my tables are NOT related; however, when the relationships are set up as the rest of the report requires, I've been unable to figure out the correct way to implement ALL/REMOVEFILTERS/similar such that the measure still works when the relationships are active.
Here's the working measure:
Distance to Owner =
var Lat1 = MIN(SystemUser[Employee Latitude])
var Lng1 = MIN(SystemUser[Employee Longitude])
var Lat2 = MIN(Account[Latitude])
var Lng2 = MIN(Account[Longitude])
---- 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))) * 0.621371
return final
Here's the SystemUser table:
| Employee ID | Employee Latitude | Employee Longitude |
| 1 | 45 | -90 |
| 2 | 46 | -91 |
Here's the Account table:
| Account ID | Account Latitude | Account Longitude |
| A | 45 | -90 |
| B | 46 | -91 |
There is an intermediate table in between the above tables:
| IntermediateID | Owner ID | Account ID |
| XYZ | 1 | A |
| ABC | 2 | B |
Relationships:
SystemUser[Employee ID] one-to-many IntermediateTable[Owner ID] , cross filter direction is single from SystemUser -- > IntermediateTable
Account[AccountID] one-to-many IntermediateTable[Account ID], cross filter direction is BOTH
The goal is to be able to calculate distance between Employees and Accounts, and I've been testing my revised measure in a matrix like this :
| | Account A | Account B |
| Employee 1 | | 5 miles | 10 miles |
| Employee 2 | | 7 miles | 12 miles |
As the measure is currently written, however, I only get the same vastly incorrect numbers (~6,300 miles) for all entries in the matrix. I expect that the solution to my issue correcting the measure to remove the filters, but I've been unable to figure it out thus far and I'm hoping someone with more experience with ALL/REMOVEFILTERS/etc. may have some insight.
