Probelm in Contact Search Help (BP_CONT_SEARCH) in CRM 7.0

Hi,

I am facing probelm in Contact Search Help.(BP_CONT_SEARCH), while creating Service Order.

In CRM 6.0 , When I press F4 for Contact, in the next screen...Account ID is being populated with a value based sold-to-party name.

But, in CRM 7.0, its not happening. I donno why.

In CRM 6.0, whther that is the standard functionality or some customization, I am not able to understand.

Please let me know, why this difference between 6.0 and 7.0.

What I need to do, to populate this Account ID value?

Thanks,

Sandeep
