How to Sort Visualization by Month

[Krahnin]

I have a report powering a dashboard visualization which I would like to sort by month (text names). Currently, they display out of order. Investigating this issue, I see other discussions where it was recommended to create a month sort column (numeric values for months) and then sort the Month column by the Month Sort column. Unfortunately, I am not having any luck with this either. I created the column without issue, but when I attempt to sort Month by Month Sort, I receive the following error: "Sort By Another Column Error. This column can't be sorted by a column that is already sorted, directly or indirectly, by this column".

I apologize about the lack of screenshots. I am not familiar with the PowerBI community and am unsure how to attach them (clicking insert/edit image does not have an option to browse and select a file from my computer).

Thanks in advance for any assistance that can be offered regarding this issue.

Did you create the sort-column as an calculation based on the origin column?

Then you should move the calculation from the calculated column in the model to a new column in Power Query, like described here:

I did not. Actually, the column is literally straight numbers within the associated spreadsheet. As I simply needed 1-12, I manually entered them as opposed to writing an equation for it. i.e. Column A (Sort Order) contains numbers 1-12 (A1=1, A2=2, etc.) formatted as Numbers. Column B (Month) contains January-December formatted as text. There is no equation from one column to populate the other in either direction.

OK.

Unfortunately I did not succed in duplicating that effect.

Could you upload your file (after you anonymonized the containing data) so I could play with it and the effect?
