Sales Representative in Retail Store

Dear Gurus,

We are tyring to capture one scenario where there are 10 sales representative in a retail store,

When sales happen, depending upon which sales rep helps the customer, he would get some commission on the total sales value.

This we want to achieve it through the POS simultation (Tcode-WPUK),

How the sales representative is created ?( through PA30 or through the XD01 with account group Sales Representative)

Is this sales representative same as the one shown in picture??(Screenshot-WPUK)

Requesting your help, (Little urgent)

Thanks in Advance

Regards,

Kevin Easaw
