Hello, I am new to OpenErp trying to build an understanding with it.I want to know how OpeneErp works. Like in accounts and finance module I am giving Opening balance to some accounts now where it's saved in database how can i see those tables or views. Now if i add or hide any field from any view where are the changes made is it also going to database or it has something to do with .py files in addons folder like it's very confusing for me what are being changed in .py files and what are stored in databse now other thing i also want to know I have Accounting and finance module set for my office now my boss says i want a new field here and somehow i manage to do it .now how can i make pack of these two things (1)changes that are made due to giving opening balance + changes are made in .py file)now i want to move the same instance(changed,customized or completely set in terms of entries and views) to my production server? please write a detailed answer that would be very helpful. Thanking you.
