You can define the elements that are part of the search for relationships
to narrow the focus of the discover function. The mappings that meet the criteria
that you specify appear in the mapping editor.
You can find relationships across all elements in the source and target.
You can narrow the scope of the search by selecting child elements of the
source and target so that the Specify Scope to Discover Relationships page
opens with a smaller set of selected elements.
Controlling the scope of the search
The Specify
Scope to Discover Relationships page of the Discover Relationships
wizard displays the elements of the source and target schemas. The elements
that are selected to participate in the discover function depend on which
elements were selected when you started the discover function. You can broaden
or narrow the scope of the discover function by selecting additional elements,
or clearing the check boxes next to elements.
The scope of the search
is selected in the following ways:
- If you right click on the target tree then the scope is the current selection
from the target tree and all elements from the source tree.
- If you right click on the source tree then the scope is the current selection
from the source tree and all elements from the target tree.
- If you right click in the mapping pane in the middle, then the scope is
the current selection from both trees.
When you use the scoping page, then the scope is preselected on the
scoping page according to the location from which you started. If you choose
to skip the scoping page then the previously described scope is used by default.
