This error usually happens under the following scenario:
- One user opens a form of a particular instance of a business object and goes away to prepare some coffee while the form is on the sceeen
- While the first user is happily drinking the coffee another user opens the SAME instance of a business object on his machine, changes some attributes and saves the object.
- The first user finishes his coffee, returns to the screen and does the same thing - tries to change the object and save. He will then get this error.
The error happens because the instance of the object has been already modified by another user. It prevents people from overwriting changes done by other users.
