Create more rows in calendar table

[Applicable88]

Hello,

how can I create new rows in power query. A join and a union is not whats working here, since there is no match on both sides.

I have a calendar:

Date		Month
08.11.2022		11
09.11.2022		11
10.11.2022		11
11.11.2022		11
12.11.2022		11
13.11.2022		11
14.11.2022		11
15.11.2022		11
16.11.2022		11

And I need the categorie a,b and c for every date:

Date		Month		Category
08.11.2022		11		a
08.11.2022		11		b
08.11.2022		11		c
09.11.2022		11		a
09.11.2022		11		b
09.11.2022		11		c

and so fourth...

Hope someone know if there is any functionality within Powerquery for it.

Thank you very much in advance.

Best.

Do a full out join between the tables using the Merge Function in Power Query.  They will need to be of the same data type, so change the date first to Text then merge then change date back to Date type.

You could create a field in both tables that have the same value and then merge on that field, e.g. TableA[Key] = TableB[Key] where Key is the value "ABC" in both.
