Set up User in Collaborative Planning

I keep reading that to set up a supplier user in Collaborative Planning in a separate machine from the EBS instance, one must:

1. Manually create the user in Collaborative Planning (using same username as in ERP)

I only entered username, password and responsibility Supply Chain Collaboration Planner.  Left the other fields blank.

2. Run Data Collection with the following parameters:

>Purge Previously Collected Data = No
>Collection Method = Target Refresh
>User Company Association = Create Users and Enable User Company Association

I tried this many times but I cannot see any effect of running the Data Collection.  Can anybody explain this to me?  What is the indicator that step 2 worked?
