Oracle 12.2 can we set a future retirement date OR adjust life in months?

Hello ,we have a list of assets for which we want to set a retirement date of 30-Jun-2030. we are trying to achieve that through the API FA_RETIREMENT_PUB.DO_RETIREMENT. But we get a error message ' Please enter a transaction date in the current fiscal year'. the API works only when the retirement date is in current year and in a open period.

if its not possible, can we use the FA Adjustment API and adjust the life in months till 30-June-2030 ? ( calculate the months between date_placed_in_service and 30-Jun-2030 , and use that value as the new life in months ? if this is a correct workaround, sometimes we get life in months with decimals like 66.75 months, but the adjustment API only accepts whole number.
