Create new table with MIN date

[ingrid]

I want to create a new table from my table with customerId and startdates which returns one row per customer with the minimum dat per customer. I've tried to use SELECTCOLMUNS and FILTER and I get a table with single customerId's but the minimum date is not calculated per customer but from the total. How can I get the minimum date per customer?

Hey Ingrid,

You can try the following:

MinFvoorzieningTbvEerste=
SUMMARIZE (
    'FvoorzieningTbvEerste',
    'FvoorzieningTbvEerste'[NrClient],
    "ingang", MIN ( 'FvoorzieningTbvEerste'[Ingang] )
)

Kind regards

Thanks @ErikHamoen 🙏 this returns the values I needed.

Hi @ingrid 

You could do something like:

New Table =
ADDCOLUMNS (
    DISTINCT ( Table1[NrClient] ),
    "DatumIngang", CALCULATE ( MIN ( Table1[Ingang] ) )
)

 You might have to filter the first argument of the ADDCOLUMNS. If you explain what the filter exactly does in your code (I don't see it completely), we can get to a more accurate answer

Please mark the question solved when done and consider giving a thumbs up if posts are helpful.

I would make this table in the query editor with a Group By step.  Or you should use ADDCOLUMNS(SUMMARIZE(... instead of SELECTCOLUMNS which doesn't do any aggregation.
