Day Name and Month Name missing when publishing to web app


i´ve created a Tile to show sales by day of the wook and another by Month.

i´ve created DayName and Month Name colums from "Date" Column using PI Desktop (Add Column>Date>Day>Name of Day)


It works well whent using it in Desktop but when i publis the report to the PI Web App the data of that columns is missing.

Other columns like "Monht", "DayOfWeek" work ok.


I´ve tried changing the language configuration from Spanish to English in Web app and the collation of the report in Destop but not result.


Does anyone have experienced a similar issue? Any recomendation?


Thanks in advance and Regards,

Hi DaniO,

Could you please share more details about the Day Name column here, the formula, and also the related data sample (what the actual data, language used)?

I tested the publish to Power BI service, with a newly created data table, selecting the column for day name works at my side:

The column is written with the following formula:

Column = SWITCH([weekday], 1, "Mon", 2, "Tues", 3, "Wen", 4, "Thu" 

               , 5, "Fri", 6, "Sat", 7, "Sun",  

                "Unknown month number" )



Please try to add related column with the data name column under Edit report View in Power BI service, see if it would make any difference.
