Hi Peter,

The Last Order Date hasn't been released at this stage 5. When it was changed to stage 6 End Of Life status, the PCN (Product Change Notification) of Last Order Date and Last Ship Date would be released.
It depends on the customers’ demands when it is changed to stage 6. If customers were placing order continuously, it wouldn't be EOL. There’s standard end-of-life notification policy (one-year notice for placement of final orders and an additional year until the last ship date).
Regards,
Lukas
