More detail message on schedule error

Hi,

Regarding the schedule error, it is log the message.
I think, it will be good to add the model id in the message.
So that, system administrator directly know which record might cause the problem.

We already have an issue on the tracker to improve such messages:

https://bugs.tryton.org/issue5581

Unfortunatly, nobody has provided a solution for it. Any help on that will be much apreciated.

How is this view activated? since it does not appear to me in version 6

The feature is available on 6.2 series. You should upgrade to such series to see it.
