Activation error for attribute view

Hi

I receive the authorisation error:

Internal deployment of object failed;Repository: Encountered an error in repository runtime extension;Internal Error:Deploy Attribute View: SQL: transaction rolled back by an internal error: insufficient privilege: Not authorized (ptime/query/plan_executor/ddl/qx_cube.cc:1560) nCreate view DDL statement: CREATE COLUMN VIEW "_SYS_BIC"."

When I validate an attribute view

I have been using the SYSTEM id in AWS HANA system.

Can anyone advise me what is wrong? I have added a schema and have added that to the sql priveleges of SYSTEM.

Thanks

Martin Davies
