If you import data into a module that uses Months in the Time Scale column, there's no impact when you change the Fiscal Year Label.
If you import data into a module that uses one of the following time scales, you may need to reconfigure your imports when you change the Fiscal Year Label:
- Periods (if you have 13 4-week Periods as the Calendar Type)
- Half Year
For example, take a module that uses one of the above time scales and run an import set to match on Name only. In this case, the import is unsuccessful, and you will see the message Invalid date or timescale identifier.
To fix imports, use the Custom fixed-position pattern import option when you map the Time dimension. Alternatively, change the time label in the source data.
