Path for libraries

in the webinar “Libraries Manager” it was said that in the sc_url_library macro you type Scriptcase for public and prj for project libraries.
For project libraries this works properly (path leads to “grp”-folder), but my public libraries are always stored in a third folder called “sys”. However, the path leads to the “scriptcase”-folder which remains empty.
Does anyone know what to do?
Best regards,

Are always stored ini “sys” because is the right place, and is not working for you because you don’t have to use scriptcase, but “sys” as target for sc_url_library macro

Thanks for your help!
