MAX DATE from One to Many relationsship

[bilingual]

Hi i have some trouble making MAX DATE work. 

I have a sheet with a unique ID and a sheet with multiple IDs , where i need to latest date to show up per each unique ID in the unique sheet.

I tried with MAX to no avail, it gives me the max date without taking into account the relationship, so all Unique IDs get the same date.

The sheets are connected with a one to many relationsship-

Hi, @bilingual 

You can easliy create a measure or calculated column to display the result.

Like this:

Measure = MAXX(FILTER(ALL(Table1),[ID]=SELECTEDVALUE(Table2[ID])),[Date])

Column = MAXX(FILTER(Table1,[ID]=EARLIER(Table2[ID])),[Date])

If it doesn’t solve your problem, please feel free to ask me.

Thanks Janey, it works perfectly, if i want to add an extra filter on it, could you be so kind to advise me for adding it to the Column ?

Column = MAXX(FILTER(Table1,[ID]=EARLIER(Table2[ID])),[Date])

Filter "Type" in Table1

Thanks

Hi, @bilingual 

I have written both column and measure methods, you can use them according to your needs. And I don't have your sample data, so I don't know what you mean about 'Filter "Type" in Table1'. Can you explain it?

Sorry for my bad explanation, i need one more condition for Max date, from Table1 there is a column named "Type" and only when Type="Flex" should maxdate be present

Hi, @bilingual 

You can simply modify the column.

Like:

Column = MAXX(FILTER(Table1,[ID]=EARLIER(Table2[ID])&&[Type]="Flex"),[Date])

New Measure
MaxDate = IF(CALCULATE(MAX(Table1[Date]),ALLEXCEPT(Table1,Table1[UniqueId]))=MAX(Table1[Date])

,1,0)
I hope this might work for your requirement .
