Dynamic Planning How to Add or Delete Dimensions from a Model

Add and/or delete dimensions from a model. When you add or delete dimensions associated with a Model, the modification affects ALL dependent artifacts. For example, if you delete a Company dimension from a Model, not only is the Model modified, but your associated reports and views are modified to reflect the deletion of the Company dimension because views and reports are dependents of the Model.

Creating a Staging Model

Complete the following steps to create a staging model:

1. Create the Staging Model
   1. Create a new staging model with the same dimensions as the source model
   2. Create a map of type ‘Both’ to move all metadata and data from the source model to the staging model
   3. Generate the staging model
2. Clear the source model and make necessary changes (i.e. adding a dimension / deleting a dimension)
3. Move the data (leaf level only) into the source model from staging model
   1. Create a map of type ‘Data’ to move data from staging model to source model
   2. Create a calculation to generate the source model and move the data from the staging model
   3. Run aggregation or any other calculations as needed to make the source model available for analysis / reporting / modeling
4. Delete the staging model

Adding a Dimension to a Model

8. Access the Model Map page. Observe the new line for the added dimension. If you select the model with the new dimension as your Source Model, the Source Filter for the new Dimension (Company) is set to DimensionFilter and the Source Value is Company (the name of the root value). The Target Filter is set to None along with the Target Value as shown below. Similarly, if you select the model with the new dimension as your Target Model, the Target Filter is set to Dimension Filter with the Target Value as the root value. The Source Filter is set to None along with the Source Filter Value.
