Thanks for quick responde,
OK
So for now it is crystal clear. Trigger is deleted. In advance UPDATE for document in database did not work properly. Changing state in database for specific document makes it unstable and causes crashing of explorer when I try to do something with it. So I deleted it also. Now I am at the same point as before :) We have PW SS3. We are not going to update to SS4 soon.
I don´t have experience with API but I could try it. Do you think that without advance skils as you have but basic (realy basic) skils with programing I could make it? Could someone of you send me a link to examples of API for ProjectWise and also example of hook programs? I need to have SDK for this kind of work?
I appreciate it
