I have a measure like below
CALCULATE(SUM(Sales[Value]); FILTER(ALL(Sales); Sales[Month] IN {"01"; "02"}))
When filtering on a slicer e.g. Department The Sales value is not changing, it's always stuck at 3500. Is there a way to filter through the rows even if the Sales[Month] Column can only be 01 02
Below is a one-to-many relationship of two tables.
Employees
Employee(Unique) Department
Cosmo A1
Kramer A1
Kessler B1
Sales
Employee Month Value
Kramer 01 2500
Kramer 03 5000
Kessler 01 500
Cosmo 02 500
Using the measure gives me row 1,3 and 4 and returns a value of 3500. If I pick department B1 I would like it to return row 3 (500) and A1 row 1 and 4 (3000).
Is there some way to make this happen? I can not use the "Edit interactions" in format, since this measure is to be used in a visual that uses other measures. I would like the measure to be responsible alone for this interaction.
Edit: If I only check month 03 in my slicer, the measure should still show values for month 01 and 02 and keep adjusting to department slicer.
Edit2: I have some pictures of my problem below:
Relationships
image of below shows Value and 1&2_Target are both 500. Whereas only Value should show 500 and 1&2_Target should be 3000. I'd like the graph to simply ignore the date slicer by the dax formula.
