Dax time intelligence functions not working

Reading from Sage I have created in my transactions table a calculated column which contcatonates the month and last two digits of the year to make a code.

 

I then link them to a calnder table which untranslates the code as a date.

 

When reference that date field in DAX it returns nothing.  I can do the same in excel and it returns values, does powerbi handle dates differently?

 

Thanks

    Hi Anonymous,

    Please help to post sample data and your expected result. If you want to use DATEVALUE function and CONCATENATE function in Power BI Desktop, you can review the following example.

    Right click you table and choose “New column”, then you can write the following formula to return date values.

    Column = DATEVALUE(CONCATENATE(CONCATENATE(CONCATENATE(Table1[Month],"/"),CONCATENATE(Table1[Day],"/")),Table1[Year]))

    Column1 = DATEVALUE(CONCATENATE(CONCATENATE(CONCATENATE(Table1[Month],"/"),CONCATENATE("01","/")),Table1[Year]))


    Thanks,

    Hi Anonymous,

    Based on the above information, it is difficult for us to analysis the cause of this issue.

    Could you please help to post the sample data of the transactions table and calendar table? Also we need to know which formulas you use to create the calculated column and DAX expression that references date field. In addition, do you create relationship between the transactions table and calendar table? If so, which columns do you use in the two tables to link each other?



    Thanks,

      Thanks lydia,

       

      I was using a text field to link the two together, but it seems that if you want to use DAX intelligence functions you need to use date links?

       

      Thanks

        Hi Anonymous,

        Could you please post sample data of your tables? And we also need to know the detailed DAX formulas that you use and how you create the relationship between tables. We will appreciate it if you can post relevant screenshots.

        Thanks,
