B2C scenario customer specific discount when customer login to the B2C site

Question

Hi E-Commerce gurus,
We want to implement a customer specific discount scenario when the customer login to the B2C web site afterwards that easily see the customer specific discount as soon as duration of the login process. We have also succeed sales org-material     scenario that according to our given below function module calculates a discount rate covers all the material within the related sales organization and also shows the indicator of discount rate on the every material pictures at the web site.
Moreover we have configured an access sequence for condition ZB2I(discount condition) that related with Sales Org.-Customer then we replicate the CNACRMPRCUS666 condition table from ECC to CRM with all values but we can not calculate and display the discount rate on the web site when the customer log on the site and/or going to the basket. 
Is there any available BADI, BAPI on ABAP and JAVA Stack. How can we display the spesific customer discount rate when the customer log on the site and/or going to the basket?
Kind Regards, 
Fahrettin

Hi,
As per my knowledge if you want to implement customer specific discount then you should use ISA B2B instead of ISA B2C. ISA B2B gives you this facility which you want to implement on B2C.
Also How you will distinguish User in B2C to display specific prise. Your discount price is based on Sales Org or base on user?
As your ABAP program is working fine but you are not getting it on web site then you have to write custom java code and collect all the required information on ISA side then pass it to RFC's import parameter and get the result back and display result on ISA B2C.
