Post PatronDISTINCT FILTER one table by another table
I'd like to create a new table, derived from filtering an existing table by another existing table using DAX only. (I do not want to use a calculated column).
Is this possible?
Example:
- I created a relationship between T1[ID] and T2[ID]
T1: (existing)
| THING_ID | VAL | VAL2 |
| 1 | X | Y |
| 1 | X | X |
| 2 | Y | Y |
| 9 | Y | Z |
| 9 | Y | Y |
T2: (existing)
| THING_ID | VAL | VAL2 |
| 1 | A | AA |
| 2 | B | BB |
| 3 | C | CC |
| 4 | D | DD |
| 5 | E | EE |
Something like:
T3 =
DISTINCT(
SUMMARIZE(
FILTER(
T1, T1[ID] NOTIN T2[ID]
),
T1[ID],
T1[VAL]
)
)
Desired Results:
T3: (new)
| THING_ID | VAL |
| 9 | Y |
| 9 | Y |
I think this does it. Please test at your side
TableT5 = CALCULATETABLE(TableT1, NOT( TableT1[THING_ID] IN VALUES(TableT2[THING_ID])))Also, in Power Query, you could Merge the two tables using a Left Anti Join on THING_ID

ericOnlineHotChilli ! Thank you! That worked. Very elegant solution compared to what I found when researching.
Do you know how to add subsequent conditions?
Example: Want to also exclude BLANKS().Added: && NOT(BLANK()) but empty results still showing.
Whats odd, is they don't appear to be BLANK() but rather empty strings. I tried && NOT(""), but they still showed up.
