Thanks, Creiss.
I followed your link and found the proper place to create it.
It is located at Tab "Infrastucture", there is a item named "Building" where location can be created.

Many thanks for your help!

Hello,Guys in I-doit
I am testing i-doit 1.8 OPEN to see if it satisfies requirement of our company. While in using it, I found a problem for me that I can't find the place to create "location".
When I am in location view, I can't see any menu for creating "Location", and I looked for other tabs such like "Software;Infrastructure;Other;Contact;Extras",There is also no such place to create it.
My question is that is this feature of creating location not available to OPEN version.
If it is not so, Can you please tell me how I can create it.

Many thanks to you all.
