Loyalty Points Redemption

Hi All, 

Can any one tell me configuration and setup for redeeming the Loyalty Points in POS. I have loyalty scheme in which i have tender type as loyalty card and i have given negative points for this. I have done payment method setup in Retail->setup->payment method as Pay Loyalty and method is card. For this Payment method i have done card setup also. 

I am able to generate issue point if i add the loyalty card to any transaction. For this transaction loyalty points are issued. Now I want to use this earned loyalty point for payment, which I am not able to do currently. 

Please if any one can help me with detail of what all are the setup we have to do to redeem earned loyalty point. 

I am trying this in Dynamics AX 2012 R2 CU7 environment. 

Thanks in advance. 

Regards, 
Abhijeet
