When to Use the AW_ACCESS Package
If your analytic workspace was created by the CWM2_AW_CREATE package, you will use procedures in that package to generate the views of the workspace. Those procedures depend on structures within the analytic workspace that are specific to AW_CREATE.
If your analytic workspace was created by some other means (OLAP Worksheet or the DBMS_AW package), you can use the CWM2_AW_ACCESS package to generate the views. CWM2_AW_ACCESS is essentially a wrapper for the OLAP_TABLE function.
