Unexpected return from TREATAS function
The problem is that you are using the wrong "manager" field in the visual: you are using the field from the Sales table when you should be using the field from the manager table:
Treatas sum = CALCULATE([Sum Amount], TREATAS(VALUES(ManagerTable[Mgr1]), Sales[Manager]))The TREATAS expression creates the virtual relationship "from" the "VALUES" expression to the corresponding field. In other words, the filter is from VALUES(ManagerTable[Mgr1]) to Sales[Manager] (The VALUES si the clue, since it creates a table with unique values, so the "one" side of the one-to-many relationship).
So you need to use the field from that VALUES expression in the visual.
Your alternative:
TestTreatas5 = CALCULATE(SUM(Sales[Amount]),VALUES(Sales[Manager]),TREATAS(VALUES(ManagerTable[Manager]),Sales[Manager]))works because you by introducing VALUES(Sales[Manager]), you are filtering to get unique manager values from the sales table, and then applying the TREATAS. So in practice the relationship then becomes VALUES(ManagerTable[Manager]), VALUES(Sales[Manger]) (so a one-to-one relationship).
Make sense?
Ideally, in your scenario, you should create a dimension table with unique values for manager and join this dim table in a one-to-many relationship with the corresponding fields in your fact tables. You then use the dimension table field in measures, slicers, visuals, filters etc...
IF not, you need TREATAS (or a suitable alternative) in all your measures...
Well, looks like the following measure works as expected:
TestTreatas5 =
CALCULATE(SUM(Sales[Amount]),VALUES(Sales[Manager]),TREATAS(VALUES(ManagerTable[Manager]),Sales[Manager])) It is still mystery for me, why previous measure doesn't work. Looks like TREATAS does ALL behind the scenes.

Great! It really makes sense. Never considered that. Thank you!
However if I place Manager from the ManagerTable I loose all the rest records from the Sales table. How do I keep them in the visual, but calculate Sales amount for the records from the ManagerTable only?
