Hello!

I have been reading and  learning on  this forum since Oct 2020 - thanks for all the great info!!

Now I have a question of my own, thought I would try the power of this forum:-)

I have already an automated action in operation that ensures that the quotations date ( when in draft or sent status) gets updated automatically to the date of editing (which is often later than the date of creation in our work flow); that works fine. 

However, the quotation's expiry date/validity date is set on 60 days by default, which gets set on the creation date, and this does not get automatically updated when editing the SO (and updating the quotation date via the automated action).

So I would like to set a 2nd line in that automated action, to define how to update the sales order for the validity field. But how do I define this? How can I tell Odoo which value to write (in fact: today + 90 days)?

I am not at all a programmer or developer, am just a 'self made Odoo superuser' in our company ...

Looking forward to your replies!
