Creating a Relationship Between Mobile Business Objects

Create a relationship between mobile business objects to associate related data and maintain data synchronization on the application device.

1. Create a link between the two MBOs:
   1. In the Palette, select Relationship.
      When you hover over any part of the Mobile Application Diagram, the cursor changes to a relationship arrow. If the cursor does not change, select Relationship again.
      
      
   2. In the Mobile Application Diagram, drag the mouse from the Customer MBO to the Sales_order MBO to draw a relationship link.
2. In the New Relationship wizard, define the relationship between the MBOs:
   1. In the General section, accept the default settings and select Composite.
   2. In the Mappings section, drag the mouse to draw a line from the id attribute in the Source Mobile Business Object to the cust_id attribute in the Target Mobile Business Object.
      Alternatively, click each attribute in turn to draw the line.
   
   
   
3. Click Finish to close the New Relationship wizard.
   In the Mobile Application Diagram, a line connects the Customer and Sales_order MBOs to show they are related objects. Different types of arrows show different relationship types, in this case, one-to-many and bidirectional relationships. You can click the objects and select the Attributes tab to see the Attributes in the Properties view.
   
   
4. Select File > Save.
