Using Globals in Fabric
Globals are predefined global variables that can be accessed by different objects within a project and are used when the same information is required repeatedly by various Fabric objects.
A Global can be used either in a map (Table Population of an LU table or a Reference table or Parser) or in a Java code (a Project function or a Web Services).
The following scenarios describe how Globals can be used in Fabric objects.
How Do I Add a Global to a Table Population?
- Go to Project Tree > Logical Units > [LU Name].
- Click Tables > [Table Name] > [Population Name] to open the existing population.
- Click the Objects tab in the right panel of the Table Population working area.
- Click Globals and then click the global in the Globals list.
- Drag the global into the working area.
- Connect the global to the table column.

How Do I Add a Global to a Parser Map?
- Go to Project Tree > Logical Units > [LU Name].
- Click Parsers > [Parser Map] to open the existing parser map.
- Click the Objects tab in the right panel of the Parser Map working area.
- Click Globals and select the global in the Globals list.
- Drag the global into the working area.
- Connect the global to the table column.
How Do I Use a Global in a Java File in Fabric?
To enable using the Globals in Java code, the following import statements are generated automatically by the Fabric infrastructure for every new Java file created in Fabric like a function or Web Service:
// import of shared Globals
import com.k2view.cdbms.shared.Globals;
// Import of Globals under the LU
import static com.k2view.cdbms.usercode.lu.<LU name>.Globals.*;
When opening a function or a Web Service in Fabric, a list of all Globals is displayed in the Objects tab in the left panel of the window.
- Globals that are defined in an LU or in Shared Objects are available for use in the LU functions of the same LU.
- Globals that are defined in Shared Objects are available for use in Web Services and in the LU functions of all LUs.
Click the grey arrow on the left of the window to display the panel and the list of Globals.

How Do I Override a Global Value?
Globals can be overridden via the Fabric Server using Fabric commands without re-deploying an LU.
- Only Globals that are not defined as Final can be overridden.
- Globals defined as Final on a Shared Objects level but are not defined as Final under the same name on an LU level, can be overridden in the context of this LU only.
- Globals can be overridden per environment.
