FI CA ( Contract accounts payable)

I don't know whether this is the right forum for asking this question:

When I am trying to create a contract account in FI CA I get the following error message

Account holder relationship is not uniquely defined

Account holder relationship is not uniquely defined

Message no. >3579

Diagnosis

Just one account-partner relationship must be flagged as the account holder relationship.

Procedure

Select the contract partner for the account that is to be the account holder, and mark the account-partner relationship as the account holder. Choose all other partners for the account and assign another account-partner relationship for these.

Appreciate help in resolving the above issue.

Regards
