MDGC 6.1 : Mass role assignment for Contact Persons BPs

Hi Gurus,

We are implementing MDGC 6.1.

We successfully generated BPs from ECC Customers. This generated BPs for Contact Persons as well in MDG.

But in BP for Contacts no role is specified. We need role BUP001 in Contact BPs to export those to a satellite system.

Unfortunately we cannot create a mass change CR for BP role.

What is the table and the name of the field for BP role?

Thanks in advance.
