Helper III

## Create the new table with DAX considering Space.

Hello.
Can Dax create the below the table ?

TableA

 SpaceNumber 3

TableB

 Category SpaceNumber Cycle A 1 5 B 2 5 C 3 4 D 1 4 E 2 3 F 3 4 G 1 4 H 2 5 I 3 3

ResultTable

 Category SpaceNumber CycleIndex A 1 1 A 1 2 A 1 3 A 1 4 A 1 5 B 2 1 B 2 2 B 2 3 B 2 4 C 3 1 C 3 2 C 3 3 C 3 4 D 1 6 D 1 7 D 1 8 D 1 9 E 2 6 E 2 7 E 2 8 F 3 5 F 3 6 F 3 7 F 3 8 G 1 10 G 1 11 G 1 12 G 1 13 H 2 9 H 2 10 H 2 11 H 2 12 H 2 13 I 3 9 I 3 10 I 3 11

Not DAX, but yes to power query.
load table B to PQ

add a new column that creates a a list from 1 to the value in number cycle. It would look something like this.

={1..[NumberCycle]}

this will give a column  containing lists. You should be able to expand this column into new rows.

Execute this code in DAX Studio... By the way, your result table from above has mistakes in it. Mine seems to work correctly.
