Remapping objects to new sources
During the life cycle of an IBM® Cognos® Framework Manager model, you may need to change the data source it uses. For example, you may want to use the model against a different database with the same data, migrate the model from a transactional schema to a star or snowflake schema, or replace a previously existing database or import view with a new view. All of these actions can affect your reports. For example, if you change the names of objects, reports may no longer validate.
You can minimize the effect of model changes and data source changes by remapping higher level model objects so that they continue to run and return correct data. When you remap, you match and substitute object references or names in an original object, to object references or names in another object. You can remap query items and measures. You can remap individual objects manually or you can remap multiple objects at the same time. When remapping multiple objects, Framework Manager matches items in the original object to items in the other object using the matching criteria you specify. Only the objects that meet the matching criteria are remapped. You can use the object name or the object reference as the matching criteria for both the original and other objects.
When you change the matching criteria for remapping, you are specifying the criteria that will be used to remap to subsequent objects.
If a model query subject or model dimension contains a filter or calculation, the model filter or calculation is also remapped when you remap the model query subject or model dimension. You do not see a message or warning about this.
Validate all affected reports whenever you make changes to your model. To identify affected reports, see Showing object dependencies and Finding report dependencies
You cannot remap data source query subjects or data source dimensions. Remapping is only supported when using the design locale of the model.
