Revert a running asset to draft

Let me explain.

I setup an asset, create its asset lines and put it into running state.

Later I realized I put a wrong start date for the asset. At this moment no move has been created or posted.

How can I revert to draft state to fix the date?

If it is not possible, how can I fix my mistake?

You should have a look to this issue:

https://bugs.tryton.org/issue9939

I guess it may be possible to allow to update the start date with the wizard as long as there is no posted lines.

I can not do that, Running the wizard let me to update the final date but not the start date of the asset.

Furthermore, I added a new comment to the issue reflecting the behavior @pokoli proposes is the expected behavior for me too.

Thank you for your quick responses .
