Error ''Person xxx (BP number) not found'' while creating a shopping cart

We are using SRM 7.0 (extended classic scenario) with SP6.

There is an error as 'Person xxx (xxx - Business partner of that user) not found' while creating a shopping cart. This is problem with only one particular user.

I have checked the roles and they are correct in portal, SRM & ERP.

When I perform consistency check by running HRALXSYNC for that particular business partner, there is an error as 'Address is not determined for an employee xxxxx (here xxxxx is GUID of employee)'. I have checked the address for this particular BP which is maintained correctly.

I have also checked the address for organization which is maintained correctly (also checked in HRP1028 table).

I have checked the relations which are maintained properly in BUT050.

Your suggestion on this would be appreciated.
