Data Type Change

My table has a column of type text. It stores the name of the month abbreviated and current year hyphenated.

 

Under column tables tab, once I click the field, can I change the Data Type to Date? Or will this cause internal problems?

It depends on how that column has been used in your model in various calculations. As per your description, it is a text field, the best practice is to creat a dates table and link it to your fact table. you create a dates table with the following"

Dates = ADDCOLUMNS(
   CALENDAR("01/01/2021","31/12/2021"),
   "Month No" , MONTH([Date]),
   "Month Name" , FORMAT( [Date] , "Mmmm" ),
   "Year" , YEAR([Date]),
   "Month Year No" , (YEAR([Date]) * 100) + MONTH	([Date]),
   "Month Year" , FORMAT( [Date] , "Mmm yyyy"),
   "Quarter" , QUARTER([Date]),
   "Year Qtr" , FORMAT( [Date] , "YYYY \QQ"),
   "Week Day" , WEEKDAY([Date],2),
   "Week" , FORMAT( [Date] , "Dddd" )

)

.

Thanks @Fowmy ! I managed to do a DAX namely FORMAT([text_column],"MMM-YYYY") since my text contains the month name abbreviated and current year hyphenated.
