Select Max Values by Category within an Filter

Hello,

first of all to the circumstances I´ve got right now:

I have a sql database witch record the movement of some matiraial throg a automatic production line.

Now I want to know how many materials have been at any station at a givin time.

What I´ve done so far is, to calculate the count of materials which passed or stay at a station in a difined timespan.

My problem right now is that I have no idea how I get rid of the passed materials, because I only want that ones which curently stay in that position (the newest movement-time).

CylMoveCylID - CylMoveCreated - CylMoveDestination

Test_2 = CALCULATE(
COUNT('KW CylMove'[CylMoveCylID]);
FILTER(ALL('KW CylMove');'KW CylMove'[CylMoveCreated] > SELECTEDVALUE('KW CylMove'[CylMoveCreated]) -2 && 'KW CylMove'[CylMoveCreated] < SELECTEDVALUE('KW CylMove'[CylMoveCreated]));
FILTER(ALL('KW CylMove');('KW CylMove'[CylMoveDestination]=281 || 'KW CylMove'[CylMoveDestination]=282...);
)

This is the result of my query. In that example I would only like to see the newest movement of Material 20496.

How can I add this filter to my query?

Thanks in advance,

Nicolas
