I don't see any mention of this in either the admin/DS guide.</P><P></P><P>Is there any way to appropriately handle this? I was not able to find good references or suggestions anywhere online either.</P></BODY></HTML> Fri, 30 Oct 2015 20:33:04 GMT https://community.sap.com/t5/technology-q-a/gdg-generation-data-groups-with-data-services/qaq-p/11321580 Former Member 2015-10-30T20:33:04Z Re: GDG (Generation Data Groups) with Data Services? https://community.sap.com/t5/technology-q-a/gdg-generation-data-groups-with-data-services/qaa-p/11321581#M4195577 <HTML><HEAD></HEAD><BODY><P>Hi Alden</P><P></P><P>Not sure what you mean by "handle" here?</P><P></P><P>BODS does not run on a mainframe so would not natively interact with the mainframe method of referencing GDG's.</P><P></P><P>GDG file names are maintained via the catalog on the mainframe, managed by the OS.
