(Enhancements)
– you can also use CDS entities as a data source type

 Support for SAP HANA multitenant database
container tables from external containers
– Model graphical calculation views in a SAP HANA system
having multiple isolated databases containers.
– This means, while modeling graphical calculation views, you
can add data source from any of the isolated databases.
 Before deployment of models referencing external
tenant tables, schema mapping shall be set to
new physical schema
– Schema mapping extends to multiDB schemas

Time Dependent Hierarchies
 HANA hierarchies support a validity time span, based
on single point in time or a time interval the hierarchy
trees will be pruned
– Supported for Parent-Child Hierarchies
– Hierarchy source table requires two date columns
VALID_FROM and VALID_TO
*Note: Use of time dependent hierarchies using a from-to hierarchy interval query is initially
targeted for SAP Applications accessing SAP HANA hierarchy views directly via SQL and will
only be fully enabled for customer use, once hierarchy-SQL expression are documented for
external use in the SAP HANA SQL documentation.Result example from a respective hierarchy view query
From/To parameters
enable return of a
hierarchy tree including
changes at different point
in times.
From/To parameters also
require to be set as data
filters of the calculation
view data source itself.

Hierarchy SQL Integration
 Hierarchy-based SQL processing capabilities enabled
via SAP HANA View based hierarchies
– SQL processing includes hierarchy-based* filtering,
aggregations as well as analytic privileges.
 Usage scenario and enablement
– Shared hierarchies from Dimension-type and StarJoin-type
Calculation Views.
– SQL use of hierarchies needs to be activated in the view
properties (for all shared hierarchies). Once activated
custom node-column name and hierarchy-expression
parameter* can be given custom name
*Note: Use of hierarchy expression will be fully enabled, once hierarchy-
expression are documented in the SAP HANA SQL documentation.

Hierarchy SQL Integration - Additional Attributes
 Additional hierarchy attributes can be specified for use from BI
Clients (once supported) or via Hierarchy SQL Integration*
*Note: Use of hierarchy additional attributes will be fully enabled for
customer use, once hierarchy-SQL expression to leverage the
additional attributes are documented in the SAP HANA SQL
documentation.

Hierarchy SQL Integration
 Hierarchy-aggregation
– The node column can be used for group by:
– ..
Note, that the filter on the node column constrains to the hierarchy
subtree. All the descendants of the node are selected.
–Note: the Revenue and Cost column contain the hierarchical
aggregated values, i.e. the Revenue for MAJESTIX is the sum of
the revenue of all its.
The calculated column Margin (percentage) is calculated correctly
after the aggregation on each hierarchy level.
 Filtering on a hierarchy node value
– The node column can be used for filtering

Calculation Views Enhancements – Hierarchy Variables/Parameters
Hierarchy Variables / Parameters
 Variables can now be related to hierarchy attributes
 Such a variable definition has two effects:
– Hierarchical value help-display in data preview
– Hierarchical filtering for variables by applying the filter on
the node column (SQL enabled hierarchies).

Calculation Views Enhancements – Hierarchy Variables/Parameters
Hierarchy Variables / Parameters
 Variables can now be related to hierarchy attributes
– Level hierarchies value help dialogs
>> Only leaf-values can be selected

prepared, both for multiple and
single entries variables and
input parameters.

Calculation Views Enhancements – Input Parameters
Derived Input Parameter Enhancements

Derived from SCALAR Function
– Input parameter value can hence be passed into a model
based on string-type output value
from a scalar user defined SQLScript function
– The function requires to generate only a scalar output
– Mapping parameters as inputs to referenced Scalar
Functions is supported*
– Input enablement allows to override derived values from
function or procedure by client at runtime*
*now also supported with stored
procedures

Calculation Views Enhancements – Input Parameters
Derived Input Parameter Enhancements

Label descriptions in Value Help Dialogs
 Description texts can be supplied in value help dialog
to provide more value insight and context during
selection
– Supported for Input Parameters and Variables
– Labels/descriptions can either be provided as
static list or via external value help resource reference,
– For external value help resource reference,
the label column information is picked up
as description text Label column in referenced
value help view

newly referenced, indicator show warnings
Referencing a deprecated
view within an analytic
privilege

General Modeler Enhancement – Multi-Language Object Labels

classical analytic privileges, users can now use SQL
based analytic privileges as design-time objects, which
provides the flexibility to create analytic privileges
within the familiar SQL environment.

– Restrict dynamically
with by Procedure
Advantages of SQL-based analytic privileges
include simpler way of implementing more
complex filtering rules.
