I am trying to import data into my module however, i am not able to map the date format with the modules timescale, the date is in "Week 1 FY19" format and i am not sure which time scale format will be suitable for the same.
If your time format is like "WEEK 1 FY19" then you should keep it as "Match Name" in Import Mapping. Let us know if you are facing any issues with that
If you navigate to Import settings, you are able to select the format you need either from already excising options OR the custom one, where "?" replace characters which should be ignored - see the screenshot below.
Hope that helps,
The date should be formatted in - periods - custom fixed-position pattern : ???? W ??YY
Note the space must be added in after and before the question mark to match the custom date format otherwise the import won't work.
