SAP Message RTP018 - Business partner &1 is both primary and contingent beneficiary

Diagnosis
A contingent beneficiary "inherits" the retirement plan only when allprimary beneficiaries have deceased. Therefore, assigning the sameperson to be both primary and contingent beneficiary for the same plan,is not very useful.

Procedure
Please make sure that the table listing the primary beneficiariescontains different business partners than the table listing thecontingent beneficiaries.
