Membership Activity in Loyalty Mangement

Hello

A Membership Activity in Loyalty Management consists of two sets of configuration.  1. Membership Cateogry 2. Membership Types.

We have to create Membership Category in the first place and also create Membership Types. After that, we assign Membership Types to Category based on the common features of Membership types.

My question follows:

1. What is the purpose of this assignment and how does it control the process/transaction flow?

2. If there is a common (general) membership type that is applicable for two different categories (based on business requirement) can I assign it to fulfill my requirement.

As a followup question;

Can a membership type be used for two different channels (say Web Channel and Web UI) during the creation of membership activity? How this is configured in the system?

Regards

Ram
