How do I get this expression to work?

I have no idea if this is the correct place for placing this question. If it's not, please, feel free to change it. It concerns the following expression:

 

Meldingen =
SUMMARIZE
(
    'powerbi vgb_melding';
    'powerbi vgb_melding'[aanvangdatum];
    "Meldingen"; SUM('powerbi vgb_melding'[aangemaaktid] ))

 

What I want to do is, to read the amount of meldingen (tickets) and place them neatly in columns with the corresponding date. Example (if i'm being vague about things):

 

Date:                                    Tickets:

October 23, 2016                17 tickets

October 24, 2016                9 tickets

 

But if I execute the expression it gives me the following error: "The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value."

 

I already tried to troubleshoot it, but with no luck. What am I doing wrong? Forgive me if it's a typo, but this is the first time I work with DAX and  my experience with MySQL is not much either.

 

Thanks in advance

    Hi Sub,

     

    I think you forget to write the measure name, right?

     

    Sample:

     

    Column/Measure Name= SUMX(SUMMARIZE
(
    'powerbi vgb_melding';
    'powerbi vgb_melding'[aanvangdatum];
    "Meldingen"; SUM('powerbi vgb_melding'[aangemaaktid] )
),[Meldingen])

    Are you creating a table because SUMMARIZE will return a table. If you are trying to create a measure with that formula it will fail because you are trying to shove a table into a scalar.

    Hi Sub,

     

    As smoupre said, SUMMARIZE function will return a table, you need to use a new table to receive the result, you can't direct use in calculate column/measure.

    If you want to use there formula in measure and column, you need to use other functions to convert the result to value.

     

    For e.g: SUMX, COUNTROWS...

    SUMX(SUMMARIZE
(
    'powerbi vgb_melding';
    'powerbi vgb_melding'[aanvangdatum];
    "Meldingen"; SUM('powerbi vgb_melding'[aangemaaktid] )
),[Meldingen])

    Hello v-shex-msft,

     

    Thanks for the suggestion, but when I use your function it returns an error: "To use special characters in a measure name, enclose the entire name in brackets ( [] ) and add a ] to any closing brackets in the name." I've looked everywhere, but the brackets are there and none are missing as it seems.
