In offline editing, remember to save your repository from time to time.
You can save a repository in offline mode even though the business models may be inconsistent.
To determine if business models are consistent, use the Check Consistency command to check for compilation errors. You can check for errors in the whole repository by choosing File > Check Global Consistency, or in a particular logical business model by selecting a business model and then selecting Check Consistency from the right‐click menu.
The consistency check analyzes the repository for certain kinds of errors and inconsistencies. For example, the consistency check finds any logical tables that do not have logical sources configured or any logical columns that are not mapped to physical sources, checks for undefined logical join conditions, determines whether any physical tables referenced in a business model are not joined to the other tables referenced in the business model, and checks for existence of a subject area for each business model.
Passing a consistency check does not guarantee that a business model is constructed correctly, but it does rule out many common problems.
When you check for consistency, any errors or warnings that occur are displayed in a dialog. Correct any errors and check for consistency again, repeating this process until there are no more errors. An error message indicates a problem that must be corrected. A warning message identifies a possible problem. See Checking the Consistency of a Repository or a Business Model.
After upgrading from a previous software version and checking the consistency of your repository, you might observe messages that you had not received in previous consistency checks. This typically indicates inconsistencies that had been undetected before the upgrade, not new errors.
