insufficient privilege: Can't export objects in schema..user has no privilege on the underlying objects

I'm using SYSTEM user but

HDBSTUDIO continues on triggering this error when I try to export the catalog:

SAP DBTech JDBC: [258]: insufficient privilege: Can't export objects in schema DARTEL_TRANSPORTES. Can't export procedure DARTEL_TRANSPORTES.PAL_TRIPLE_SMOOTH_WRAPPER. user has no privilege on the underlying objects

When trying to grant the SYSTEM user to that particular object  I get a new error : Could not modify user 'SYSTEM'. Several issues occurred

Have anyone have struggled with this error before, any help will be highly appreciated

Kind Regards
