StackHash profiles allow you to work with different WinQual accounts or to show information from the same account in different ways.
The StackHash service can manage many different profiles, including synchronizing each profile with WinQual using the specified schedule. The StackHash client can only work with one profile at a time. You can change the current profile in Tools -> Client Options -> Service Connection.
When you run the Setup Wizard StackHash guides you through creating your first profile. In many cases a single profile will be sufficient. You can add, edit and remove profiles from Tools -> Service Options -> Profiles. This option is only available when running the client on the same computer as the service.
Each profile must have a unique profile name and local store index name. Profiles cannot share data. If you configure more than one profile to synchronize the same mapped products from the same WinQual account you will duplicate data.
It can make sense to use several profiles for the same WinQual account if you want to separate out different products. If your account contains products A, B and C you might set up a profile for each product and enable the versions of that product for synchronization. Each product team can then configure the StackHash client to use the profile associated with their product.
