Marketing status from marketed to not marketed

Hi! In case one of our product pack will change from marketed to not marketed for commercial reasons, we need to update the IRIS platform in advance but which date should we report as "Date of Marketing Status Change"? The one when we upload the information (e.g. today) or the date by when the pack will not be on the market anymore (e.g. Jan 2023)?
Thank you very much for your help

The date of marketing status change when moving from Marketed to Not market is the date of the last release into the distribution chain. Please review question 2 in Notifying a change of marketing status | European Medicines Agency (europa.eu)
