Troubleshooting the product portfolio management workspace
Fixing expressions
The business rules might be broken when you export and import the workspace. You must activate the predefined expressions and business rules in the product portfolio management workspace. Because some predefined expressions contain database IDs that are unique for each environment, the expressions must be refreshed. You must refresh the expressions once for every workspace. You can find the database IDs for your environment in the user interface of the product.
