SAP Message RTP021 - There are &1 contingent beneficiaries. Enter 1 primary beneficiary.

Diagnosis
Contingent beneficiaries are only relevant in the case that all theprimary beneficiaries have passed away. Associating only contingentbeneficiaries to a retirement plan without having at least one primarybeneficiary has, therefore, little meaning.

Procedure
Either enter at least one primary beneficiary in the table, or removeall the contingent beneficiaries.
