Check to Use customized Calendar-Year as Fiscal Year with Friday Month-End (instead of K4)

[SAPSupport]

Hi Team, 

        We are currently using fiscal year variant K4 (Calendar Year: 12 normal + 4 special periods) in our DEV & QA tenant.
Our business requirement is to keep a calendar-year fiscal year (Jan–Dec)   but have each month end on a Friday . If the last calendar day of the month is not a Friday, , the month should extend to the following Friday, , even if that Friday, falls in the next calendar month. This “Friday,  month-end” rule must apply consistently for all months and years.

We need SAP confirmation on supportability in S/4HANA (Public Cloud) and the exact enablement steps. Our Production system is not yet set up and there are no productive postings, so we want to implement this now if possible.

Hence requesting to provide your expertise advise in this at the earliest.

--- Steps to Reproduce ---

1. Use SSCUI DIGITS - Maintain Fiscal Year
2. Use "SZ-Configurable template variant" or New Entries
3. Configure the each period with ending PERSON_NAME
4. Assign that FY Variant to Company Code - SSCUI-DIGITS (we are not able to change here)
