reset/undo the Deletion Indicator in the Prod Orders

Hi Friends,

I have set the Deletion Flag and feletion Indictor inthe Prodcution orders in order to prepare them for Archiving. Now I want change some of them.

But I am unable to go into Change mode of Prod Orders(CO02). Message says Prod Order is already deleted and hence can only be displayed.

How can I reset the deletion Indicator?

Thanks

Siva
