Problem with customer_rel

We are on CRM 5.0 with R/3 4.7. We have implemented note 914437 and consequently created FM Z_PI_BP_ROLE_MAP_DE_EIOUT in R/3. I have also run program BUP_ROLE_CUSTOMER_CONVERT for the required customer. I run R3AS for 'customer_main' and 'customer_rel' for customer 66457 and 22. Customer 66457 has itself and customer 22 as ship-to-parties. In SMW01, everything is successful. When I go to BP, I am expecting to see a separate tab for ship-to-party 22. I don't see this. What am I missing? All responses will be suitably rewarded.

Thanks
