Dear Community,
first at all I want to wish everybody a really nice year. I hope u'll enjoy it!
We have a small issue in our CRM Master Data, which make me a lil bit nervous.
A lot of our products received a warranty by migration. We have to delete this warranty in each product.
The Second point is, that I have to enlarge some products to other distribution chains with proper tax codes.
For both issues I'm searching a mass change possibility ? In ERP it's very easy but CRM is really new for me.
Do u have some ideas ?
Would be nice, if some guys will help a CRM newbie 
Thank u so much! - Greetz, t0pzi
