HANA

In HANA version: 2.00.048 You can observe some memory leak. The problem is mainly visible in this collector: Pool/RowEngine/GlobalHeap. It can use 70-80GB of RAM and more during calculations. SAP note 1999997 indicates that the problem can only occur until Hana 2.00.046 but we already know that’s not true. Meanwhile a note 2902494 says about leaks on this pool, but still doesn’t provide a solution. Parallel to the above allocator, you may also observe a problem with another allocator i.e. Pool/RowEngine/QueryExecution/SearchAlloc.

HANA – Ptime Exception: insufficient privilege: [2950] user is not authorized : occurred while unfolding

In a few words, I will try to outline the situation in which I get the error mentioned in the topic of the article.

Firstly, technical user was created to access HANA Calculation Views (CV).
Secondly, CVs are built in specific package and they are using data from other packages.
Thirdly, user can access one CV, which built as a projection from database table and is joined with two CVs generated by BW (master data).
