Summary

• You can create instance lists that contain more than one type of object. You do this by defining relationships between business objects. The relationships can either be peer-to-peer or parent-child.

• In situations where you want to completely fill the business object instance list programmatically, the filter has no meaningful interaction with the end-user and can be hidden from view.

• A relationship handler is an RDML function that is called to dynamically expand the relationship between a parent and child object. By doing this you can improve filter performance by only adding root or parent objects to the instance list initially.

• The Framework instance list can display up to 10 alphanumeric and/or 10 numeric additional columns in an instance list.

• The Advanced section of the Programming Techniques sample application has examples of advanced instance lists.

• LANSA supplies a sample relationship handler to copy from when creating your relationships.  The source is stored in function DFREL01 in the process DF_PROC.
