Add columns + related function with many-to-many relationship / merging two calculated tables

[sbenzaquen]

Hi,

I would like to merge the following two calculated table:

Table 1: Year/month - team - team count - working days

Table 2: Year/month - team -  days-off

I would like to bring the days-off data over to table 1 as an additional column. I tried using ADDCOLUMNS+ RELATED functions but is not working because i.) they have a many-to-many relationships and ii) they are calculated tables I can't merge them using PQ which would be ideal as the days-off result will depend on two variables the month/year and team.

How could anyone please help me to solve this issue?

Thank you in advance,

Salvador

Hi @sbenzaquen ,

To my knowledge, RELATED() works only for side 1 of the relationship.

Since the relationship in your data is Many to Many,it's suggested to use RELATEDTABLE() instead.

In addition, if the days-off is unique based on each YearMonth and Team, you could use LOOKUPVALUE() like this:

Dayoff = LOOKUPVALUE('Table2'[Days-off], 'Table2'[Year/Month],'Table1'[Year/Month],'Table2'[Team],'Table1'[Team])

If it does not make sense ,please provide me with more details about your table and your problem or share me with your pbix file after removing sensitive data.

Thank you @v-eqin-msft .

Your solution was not working initially because I the same year/month multiple times for one team. But I fixed it using Summerize + Roll up function.

All working well now.

Thanks,
