Finnish Deferred Depreciation Report doesn't work as per user guide.

Dear team,It is mentioned as per user guide that "In Finland, tax book depreciation is calculated at the category level. This affects the tax depreciation calculation of assets sold during the year because Oracle Assets generates loss/gain amounts based on individual assets, not on the whole category. Because calculation on individual assets is illegal in Finland, Oracle Assets sets up each category with a new sales asset. It creates new sales assets for the categories at the end of each financial year."

I did try to test this functionality but not able to find how and when the Sale Asset gets created.Please let me know if any step is missing as I do not find more information in the user guide/Localization country sheets.
