HR-LDAP Synchronisation using report RPLDAP_EXTRACT

hello, is there anybody here has done the HR-LDAP synchronisation using report RPLDAP_EXTRACT?

I need some help on this one. I've done the mapping in transaction LDAPMAP, setup the mapping for structure EMPLOYEE for the standard query LDAPEXTRACT46C. However I get an error when I execute RPLDAP_EXTRACT.

the error in report SPLDAP_DISPLAY_LOG_TABLES says "No data found for field P0000_PERNR of structure EMPLOYEE".

thanks.
