Ortems - Unlaunching WO that is in progress in WIP Control

Hi,

I am enquiring on how and if it's possible to unlaunch a WO that has a status "in progress". When I try to in the WIP Control, it comes up with "WO in progress: cannot be unlaunched".

I have tried to modify my WO's in the table B_OF, in the column ETATOF from 'E' for in-progress, to 'O' for open. But it appears to have no impact on the status in WIP Control.

I have tried to find details in the documentation. Is it not possible to unlaunch a WO that's in the state in-progress?

Any assistance is appreciated.

Thank you
