Hi everyone,
 
is there a possibility to create a rule that does the following:
 
Article is sold out -> quantity is 0 in magento
 
at the moment we:
- set quantity to 100
- make article available so it can be ordered
- set shipping time to 4-6 weeks
 
what is our goal:
automatically update to quantity 100, "article is available" and "shipping time 4-6 weeks".
 
At the moment we have to do it manually. 
If there is an extension or kind of rule you guys know, please tell me.
 
Best regards,
Philipp
