Business partner option not available in BUT000

Hi Guys,

I need a help from you all,

In my system (CRM 5.0)

When you go toT.Code BP and search for customers by pressing (available

options) there are search term

a. partner by address b. partner by bank details

where you will have options to select the customer.

It is ok.

But when i go to SE16 ->BUT000 to give me the list of ciustomers by pressing

F4 Iam not getting the options

But rather i get 1,2,3 .... 10000 customers..

where this is controlled .. Please it is very urgent.

Regards,

Satish
