case, the name of calculation view and analytic view is same as that of the InfoCube and the name of the analytic<br />

view is suffixed with _INTERNAL. The analytic view generated in the case of an InfoCube is used internally for the<br />

generation of the respective calculation view and is not available for client consumption. If you select a<br />

QuerySnapshot InfoProvider, the resultant <strong>SAP</strong> <strong>HANA</strong> model is an analytic view.<br />

When you choose to import the <strong>SAP</strong> NetWeaver BW InfoProviders, the analysis authorizations set on the<br />

InfoProviders are also imported as analytic privileges in the <strong>SAP</strong> <strong>HANA</strong> Modeler. The name of the analytic privilege<br />

is the same as that of the BW Analysis Authorization object. These analysis authorizations set on the<br />

InfoProviders are applicable at runtime for reporting.<br />

Note: In the case of Query Snapshot, all the BW Analysis Authorization objects which are applicable on the<br />

underlying InfoProvider of the query, will also be applicable on the Query Snapshot. These BW analysis<br />

authorization objects will be imported as analytic privileges when importing the query snapshot.<br />

The generated models and analytic privileges are placed in the sap.bw package. You can choose to enhance the<br />

generated models. However, with the subsequent import of the same objects, the changes are overridden. Also,<br />

changes made to the models on BW side are not automatically reflected in the generated models. This may lead<br />

to inconsistent generated models based on the changes made to the physical tables. To avoid this, you need to re-<br />

import the models.<br />

Caution:<br />

● The calculated key figures (CKFs) and restricted key figures (RKFs) defined on the <strong>SAP</strong> BW models<br />

are not created for the generated <strong>SAP</strong> <strong>HANA</strong> models. In this case, you can create an RKF as restricted<br />

measure in the generated analytic view. For CKF you can create calculated measures in the generated<br />

calculation view or analytic view. These CKFs and RKFs are retained during subsequent import. If a<br />

change is made to the characteristics or key figures based on which these restricted measures and<br />

calculated measures are created, this may lead to inconsistency in the generated models. In this case,<br />

you need to manually adjust these restricted measures and calculated measures.<br />

● The restricted measures and calculated measures that you define for the analytic view that<br />

correspond to a query snapshot, is overwritten with the subsequent import.<br />

● The BW analysis authorization objects are not always mapped 1:1 with the generated analytic<br />

privileges on the <strong>SAP</strong> <strong>HANA</strong> Modeler side. If the BW Analysis Authorization object does not include<br />

0TCAIPROV, the authorization is not moved to <strong>SAP</strong> <strong>HANA</strong>. Also, restrictions created in the BW<br />

analysis authorization are skipped if they do not match with the restrictions supported by the <strong>SAP</strong><br />

<strong>HANA</strong> Modeler. In such cases, the data available for reporting for a <strong>SAP</strong> <strong>HANA</strong> Modeler user differs<br />

from the <strong>SAP</strong> NetWeaver BW user with the assigned restrictions.<br />

For reporting purposes, data which is visible for a user is:<br />

● For a DSO generated analytic view, all the data in the active table is available for reporting.<br />

● For an InfoCube generated calculation view, only successfully loaded requests are available for reporting<br />

(these are the green requests in manage InfoCube section).<br />
