tamerj1 thank you, but not quite what I was looking for.
For example, for Equipment key 1104, it should just "Else=0" because there is no previous equipment key record for that equipment. In Equipment 1106 it should calculate the "current - previous" mileage because there is a previous entry.
What it should look like:

Perhaps I misunderstood your requirement. I'm still not sure if I fully understand 🙂
Please try
Variable Difference =
VAR CurrentDate = 'PM On Time Performance Bus PM-BI-002 (2)'[Completion Date.Completion Date Level 01]
VAR Curr = 'PM On Time Performance Bus PM-BI-002 (2)'[Mileage]
VAR CurrentEquipmentTable =
CALCULATETABLE (
'PM On Time Performance Bus PM-BI-002 (2)',
ALLEXCEPT (
'PM On Time Performance Bus PM-BI-002 (2)',
'PM On Time Performance Bus PM-BI-002 (2)'[Equipment.Equipment Level 01.Key]
)
)
VAR TableBefore =
FILTER (
CurrentEquipmentTable,
'PM On Time Performance Bus PM-BI-002 (2)'[Completion Date.Completion Date Level 01] < CurrentDate
)
VAR PreviousRecord =
TOPN (
1,
TableBefore,
'PM On Time Performance Bus PM-BI-002 (2)'[Completion Date.Completion Date Level 01]
)
VAR Prev =
MAXX ( PreviousRecord, 'PM On Time Performance Bus PM-BI-002 (2)'[Mileage] )
RETURN
Curr - COALESCE ( Prev, Curr )tamerj1 yes this is almost exactly what I need! the formula is working great, just need to add the contional rule on top of it.
so, if there is there is no previous matyching equipment ID the Variable Difference formula should equal 0.
if there is a previous equipment ID, the formula needs to run.
In this example, the equipment key = 1104, variable difference should yield a "0" because there is no other previous record of 1104.
But the second record of1105 is correct, because there is a previous record.
Strange! It should return 0. Actually this is the purpose of the COALESCE. Would you please share the code that you have used?
tamerj1 I used the one you provided above.
Only other thing I could maybe think of is a Date Slicer added using, "Completion Date.Completion Date Level 01"
