You can combine the work of several groups in your enterprise
that have mapped relationships by using the function to combine mapping
models.
Before you begin
You must have at least two mapping models in the current
Data Project Explorer view.
About this task
You can transform a series of relationships by combining
mapping models from multiple mappings to one mapping, or from sequentially
created mapping models to another mapping model.
Procedure
To combine mapping models:
- In the Data Project Explorer view, expand the data design
project that you want to work with.
- Select Mappings.
- Right-click on a mapping model that you want
to use as the model that you combine other models with.
- Select Combine Mapping to open the Combine
Two Mapping Models window. The mapping type depends on
the content of the mapping model that you selected. For example,
Combine Parallel Mapping Models |
You combine mapping models in parallel when you create multiple
mapping models that might contain different sources but use the same
target. You combine two of these mapping models to merge information
into a third mapping model. |
Combine Sequential Mapping Models |
You combine mapping models in a sequential order when you
create a mapping model with a source and a target, and then use that
target as the source for a second mapping model. This action creates
a third mapping model that contains the source of the first mapping
model and the target of the second mapping model. |
- In the Combine with group box, specify
a mapping model to combine with the mapping model that you selected
in step 3.
- In the Resulting mapping model group
box, specify a file name for the new mapping model.
- Click OK.
Results
Each group box contains source and target information that
is related to the selected mapping model. The new mapping model that
is a combination of two other mapping models is added to the data
design project in the Data Project Explorer view and saved in the
current workspace.
