How to return me the "smallest" subtopic for each topic

Misha — Wed, 17 Aug 2022 07:02:49 GMT

Situation

- I Have 2 tables, the first one contains 'Topics', the second one contains multiple 'subtopics'

Question

- How can I get a column returned that exists of each topic in combination with only the 'smallest' number of subtopic for each topic

Tx in advance!

Please try following DAX:

Column = IF('Table'[Subtopic] = MINX( FILTER('Table','Table'[Topic] = EARLIER('Table'[Topic]) ), 'Table'[Subtopic] ), 'Table'[Topic])
