Before you can execute a calculation script in Administration Services, you must save it as an artifact on an Essbase Server, a client computer, or a network. See Saving Calculation Scripts.
When you use Administration Services to execute a calculation script, you can execute the calculation in the background so that you can continue working as the calculation processes. You can then check the status of the background process to see when the calculation has completed. See “Executing Calculation Scripts” in the Oracle Essbase Administration Services Online Help.
