Customer number of business partner can not be determined

Hello,

I created the BP for role TR0100 Main Loan Partner and I also added the role for FLCU00 for FI Client where I put the Company Code information and link this BP with the customer number in FI.

When I am create a general loan (SAP Banking) the system did not determine the customer number in the Partner view, so when I go to make a Disburse (FN5V), I put the company code and the contract number, and then I get the error message "Customer number of main loan partner cannot be determined" Message no. 67087.

I have reviewed the configuration and the SAP help for this scenario but I have not resolved this problem. We are starting this project so do you think this error could be generated because FI has not been fully customized ?

Thank you for your help.
