Hi to all,
i have a problem, no matter how try but in every ODS view that i create, it never shows "CalcScenario Used" "Yes" and, for this reason, i cannot do the join in my composite provider involving the ODS View.
That's the screenshot:
I have done a calculation view and used a remote source to create a Virtual Table to upload it in the ODS View.
It seems to me that i have satisfied all the requirements.
I am using this guideline:
Solution
As of BW 7.40 SP8, the Open ODS View supports HANA Optimized Query Execution using the SAP HANA Calculation Engine. Depending on the BW query mode, certain OLAP calculations can be pushed down to HANA to optimize the query runtime.
As a prerequisite, a column view of type Calculation Scenario is required. The Open ODS Views of semantic "Facts" now have a new property called "CalcScenario used". The property describes if such a Calculation Scenario has been created. No user interaction is required, since the property is automatically determined during InfoProvider Activation.
Prerequisites for Calcuation Scenarios of Open ODS Views
- Semantics:
A Calculation Scenario is only created for Semantics 'Facts'. Associated Master Data (InfoObjects, ODS Views) are contained in the Calculation Scenario. - Source Types:
Supported Source Types are 'Virtual Table using SAP HANA Smart Data Access', 'Database Table or View' and Advanced DataStore Object. - Source Object:
Only Column Store Table and Virtual Tables are currently supported. Rowstore Tables or Database Views are currently not supported. This prerequisite also applies to all associated ODS Views. - Field Data Types of Source Object: Certain Data Types can not be supported yet as view fields in the Calculation Scenario:
- Binary types (VARBINARY, BLOB) are in general not supported in the ODS View.
- LOB Data Types: CLOB, NCLOB, TEXT, BINTEXT
- Fixed-point decimals (e.g. DECIMAL(p,s)), which have an association to a BW Keyfigure with floating point number
- Fields with associations to BW Keyfigures with datatype decimal float 34
If you need further information, please ask.
Sorry in advance if my question is not elaborated well enough but i am still a newbie with Hana Studio.
