Hello Thomas,
in both cases these are catalog roles owned by the user who created them.
Actually the sample where we experienced this was a SAPINST installation.
We currently roll out multiple SAP suite systems on HANA and e.g. on the BI installation the ABAP* roles that are created during the installation are not directly granted to the user who owns/created them (SAPSID) where the same roles generated on a e.g. SRM system installation are directly granted to SAPSID.
In both cases SAPINST created these roles as catalog roles using the SAPSID user.
