Mass change TECO > Release > and Deletion Flag

Hi guys!

I need change a lot of production's orders, from TECO status to Release status.

I know that I can do that by CO02 - functions and revoke the status, but we are talking about more than 1400 items.

I thought that I could mass change on COHV, but I could not. Probably because I dont know exactly what fill on the fields, or cause is not possible make this massive change.

Well and after make this massive changes, I need make another change that is select Deletion Flag for all the items

Anyone could say if it is possible make this changes on massive way or if is just one by one?
