Enabling R3 Account Grp

Hi All,

I am have this problem with the 'Account Group' in the 'Classification' Tab in the BP transaction. By default this field is disabled. I want this field to enable so that I can specify the account group in here while trying to replicate this customer.

We currently upgraded to CRM 5.0. In our old system CRM 4.0 we had this field enabled to so we could enter the account group in here. I am not sure how to enable this field? I really appreciate if anyone out there could mail me the solution.

Thanks in advance,

Karuna.
