(Another) Sort by another column problem
I believe I've solved this problem. It was caused by a relationship between my date table and a fact table. The relationship was between a calculated column in the latter that looked up a value from a column in the former. Power BI allowed it, but it seemed to affect the behaviour of reports built using the dataset.
Removing the relationship means I can perform the sort I need.
To recreate the relationship, I've calculated a table in the query that include only the columns I need and inserted this between to the two tables in my model.

You've identified this table as a 'Mark as Date Table' correct? Can you provide a sample?
No, I haven't marked it as a date table. I don't need to use the time intelligence fucntions as my calendar has custom periods. I'd be happy to provide the csv but I don't have anywhere I can upload it that I can access as work.

Are they not custom periods based off of sequential dates? Those dates become the sort order. Time Intelligence functions do not need to be utilized just by marking as a date table.
I built a custom period calendar table, marked as date table, and have had no issues with sorting. Possibly it is just the implementation you've chosen that is causing intermittent successes.
Are they not custom periods based off of sequential dates?
Yes, but the periods change slightly each financial year. For example, 29th April can be in Period 1 or Period 2. The logic for this is implemented.

I wish to sort by Period/Fiscal Year for visuals. If I don't do this, the x-axis of a chart showing the last 13 periods of data would put period 13, 2018/19 after period 1, 2019/20. Hope that makes sense.
I can certainly try marking it as a date table, I'm just not sure why this would matter!
