Error generating RFC connections when using the wizard in SMSY

We are using the wizard in smsy to generate the rfc destinations but the error

Error create rfc destination back and also no read destination assigned for read access.

The user has s_rfcacl assigned on both sattelite and solman system and

we have tried deleting and recreating (by rerunning the wizard) rfc

destinations. We have also tried to manually create the rfc

destination. Any help appreciated.
