SAP HANA clone user

SAP HANA have copy user function.
That function only clones roles given by _SYS_REPO.
Also function does not copy any of analytical privileges.

Below piece of sql creates a function to clone these objects.

Code checks if user exists if not create.
Only select roles with GRANTOR "_SYS_REPO"( this is my business requirement. You can change the way you want.
Only select privileges of type SQLANALYTICALPRIVILEGE and ANALYTICALPRIVILEGE.

use GRANT_ACTIVATED_ROLE and GRANT_ACTIVATED_ANALYTICAL_PRIVILEGE methods go grant these objects.
