partner roles

Dearall,

I have an issue . I have created an BP role landlord with vendor account and Master tenant with customer account. I have assigned this role categories to the applications. In the contract types also I have assigned the role main contractual partner as landlord with vendor account for commercial lease in and master tenant with customer account in the commercial lease out contract.

Now I have created the contract and assigned the partner role as Landlord with vendor account. After assigning this and proceeding to the next tab system is giving a message land lord with vendor account has not been assigned. Infact I have assigned the role but the system is giving the eerror message. Experts please suggest.

Regards.
