lookup values from another table, if values exist in another table, return 1 to get the filter show

[Anonymous]

Hi, experts, I have two tables, dimension table and fact table, I created a filter use column from dimension table, but fact table may not exist some values in dimension table, and I need to make sure all the values from the fiters selected has relevant data, do you have any ideas?

My idea is that creat a measure in the dimension table, when the value from fact table exist in dimension table, then return 1, else 0, and apply this measure to the filter, but the measure crteated is not work.

here is the sample data and expected result:

dimsention table

region

A

B

C

fact table

region	data
A	adaf
C	fadfa

expected result:

region	measure
A	1
B	0
C	1

I created mesure like this: 

measure=

VAR _fact=MAX('fact'[region])

VAR _dim=MAX('dim'[region])

RETURN IF(_fact=_dim,1,0)

but the measure did not work

do you know how to how to make this measure correct or any other ideas on make the slicer show only relevant data?

Hi @Anonymous 

You may try this measure

Measure = 
var __values = VALUES('Fact'[region])
return
IF(SELECTEDVALUE('Dimension'[region]) IN __values, 1, 0)

Try Countx

Relevant Data Measure = VAR _fact_region = 'fact'[region] VAR _dim_region = 'dim'[region] RETURN IF( COUNTX( 'dim', _fact_region = _dim_region ) > 0, 1, 0 )

It will count the number of rows in each.

This measure has error: the function countx cannot work with values of type boolean

Try changing the data types ? or use "1" and "0" instead of 1 and 0
