See the image below. The metric "Measure" was not calculated for Total line. How do I identify the total line? You need to understand how filter context works. On a high level each cell is calculated independently in a matrix. In the example,
for the first line, the table "Table" is filtered for date 01/01/2020 and sums the sales column for the returned rows.
for the second line, the table "Table" is filtered for date 01/05/2020 and sums the sales column for the returned rows and so on. So each row has a date filter which filters the table "Table" based on defined relationship. But the total line does not have any date filter. When the condition fails in HASONEFILTER, it just blanks out based on the measure formula.
Read this article to better understand the concept.
Thank you for the through explination and the example.
If I understand correctly I need to replace my current Date of registrtion request column with the measure:
2nd Date of registration request = IF(HASONEFILTER('Rama + Adi merged'[ shem_fakulta_1-EN]]),[missing second argument] , BLANK())
All the other columns in this matrix are based on measures and I they don't appear on the drop down for the SUM function, what DAX function can I use instead of SUM which requires columns? Or is there a way to sum all except the one date column?
Attaching a screenshot of my matrix columns - the one I don't want to total is the only date.
