If you receive a notice that states "current fiscal year end date" you will need to include your Fiscal Year End Date in your DEI section of your 8K document. The format of the date needs to be --MM-DD format or the tag will not be read correctly. You will create a fact for the cell and select the concept 'Current Fiscal Year End Date'.
Once updated, the notice will be cleared from the filing and you will be able to test file successfully.
