The list generated
by inquiry or JPO might contain more information than the OID and RelID.
This special information may not be available at a later point for displaying
as column values. For example, when doing an expand on a part for relationship
EBOM, the level information is available, but cannot easily be obtained
from the resulting object list.
To make this special information available for column values, you
can obtain it when fetching the object list. You can store it in the
object list map with a pre-defined key. To display these values in a
column, configure a column as Column Type=program, use the Object List
Map to obtain the values and display them as column values.
