Good day to all ,

I have a situation where i want to group customers based on type . The two types are Small shops and Supermarkets. I have grouped the customers . However i face a challenge in which i am needed to filter the customers based on some form of selection criteria like a parameter . I have one group with all customers which are broken down into two groups. Any suggestions as to how i can get my selection from the parameter to control and list the data for that specific group . rather than all the data.
