Error message when create maintenance orders with a past date

Good day,

I've create a maintenance plan on 26/02/2019 that must have started at the begin of the same month.

When I clicked on Add button, the next error message appeared, "Error when entering date".

In spite of the message, the maintenance plan was created but none maintenance order has been generated.

So, beas doesn't allow to create maintenance plans with a past date.

I think this functionality could be improved in future releases because it's usual that a user needs to create a maintenance plan in a past date.

And no less important is to have a tool that let us to import Maintenance plans. I have to create manually more than 2,000 plans and it's awfull.

Thanks.
