Defining application schema metadata

After you create a custom table or a custom column on a standard table, define any needed metadata:

Use the Application Schema Modules Metadata form to define any custom modules.
Use the Application Schema Tables Metadata form to perform these actions:
- Assign custom tables to the appropriate module.
- For backward compatibility with existing multi-site tables, assign a view name. The view name should match the former table name. For example, a table formerly named item which is now item_mst would have a view named item. Specify a column name that contains the site value. The combination of view name and site value is used to create a view over the table.
- Specify information about insert and update triggers on the table.
  Note: To exclude certain columns that typically trigger large amounts of replication generation, you can register those columns in the AppTable table, using the Skip Replication Noisy Columns field on the Application Schema Tables Metadata form.
- When UETs are added to the currently selected table, specify any other tables to which the UETs should be applied.
If a table has an AlphaKey (you want to generate Next Keys for a column in the specified table), use the Application Schema Columns Metadata form to define this.

If you later remove a custom table or column from the application database schema, you must also remove the corresponding row from the application schema metadata, if that row exists.
