As of Release 2.1D, only authorization profiles which begin with character string S_A. are supported in the Basis system. All other delivery profiles which begin with S_ are not maintained any further and deleted in a later release. Therefore, you have to make sure that only the profiles supported by the base delivery profiles are used in own your collective profiles and users and that all other base delivery profiles are deleted. This does not apply to the customer-specific authorization profiles which should not have an underscore '_' at the 2nd position in the first place.
