Since ServiceMax is built on Salesforce, you would need to refer to Salesforce help / training at times. You can access Salesforce help from your org itself by clicking the Help & Training link at the top right corner of the home page.

The Salesforce Help & Training window includes the resources you need to be successful with the Salesforce application. You can find answers to your questions by typing keywords in the search area or by navigating through the index on the left. You can also download Tip sheets and best practice guides from the Help & Training window.
