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

http://service.sap.com/sap/support/notes/1811723



Calculation Views Enhancements – Hierarchies

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



Calculation Views Enhancements – Input Parameters/Variables

Multiple default values

Multiple default values can be

prepared, both for multiple and

single entries variables and

input parameters.



Calculation Views Enhancements – Input Parameters

Derived Input Parameter Enhancements

Derived parameter values now support

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

Input Enablement

– Input enablement allows to override derived values

from function or procedure by client at runtime*

– Input enable, override the default value coming from

procedure/scalar functions or table



Calculation Views Enhancements – Value Help Dialogs

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 textLabel column in referenced

value help view

SAP HANA Studio Modeling

EnvironmentNew capabilities and enhancements in the Modeler- and Development perspectives

in SAP HANA Studio



General Modeler Enhancements – Using Views / by Name

Easier use of View Name

– Input Parameter, Variables, Hierarchies, …

Comment text available via

maintain dialog or

object context mouse

over action



Calculation Views Enhancements – Data lineage

General Modeler Enhancements – Rename Views and Columns

Refactoring - Rename Information Views and Columns

Rename views or its columns includes propagation to

impacted objects

– References to renamed views or columns within impacted objects

will be automatically adjusts and thus the references maintained.

Rename of View



General Modeler Enhancements – Rename Views and Columns

Refactoring - Rename Information Views and Columns

Example: rename of a column and its references

– Lists impacted views, analytical privileges …

– If not chosen, impacted objects need to be manually adjusted

– Save will run the job

Semantic node, column tools

Note: Only if objects are closed, renaming will be propagated.



General Modeler Enhancement – Deprecate Views

Deprecate Information Views

New View Property “Deprecate”

– Deprecated information views signifies that the

information view is supported to be queried, but it

is not recommended to use them in other

information views or

in analytic privileges.

– Warnings will show up, when a deprecated view is

newly referenced, indicator show warnings

Referencing a deprecated

view within an analytic

privilege



General Modeler Enhancement – Multi-Language Object Labels

Multi-Language Object Labels

Maintain Object Label Texts in Multiple Languages

– SAP HANA modeler supports maintaining object label

texts in different languages.

For each object label, other than in the default language

text, choose from additional languages to maintain object

labels.

– For activated models, translation enabled by default

if switched off, additional language texts will be deleted



General Modeler Enhancement – Data Preview

Modeler Data Preview Enhancements

development perspective

Designing Analytic PrivilegesEnhancements to Developing Analytics Privileges in SAP HANA Studio



Analytic Privileges Editor – SQL-based Analytic Privileges

Create SQL-based Analytic Privileges

In addition to the existing approach of creating

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 by Attributes

– Restrict by SQL expression

– Restrict dynamically

with by Procedure

Advantages of SQL-based analytic privileges

include simpler way of implementing more

complex filtering rules.




Create SQL-based Analytic Privileges

Start with general Attribute based AP, then switch to SQL-based

Note: when switching from Attribute- to SQL-based Analytic Privileges, an intitial SQL-based

restriction is generated from previous attribute settings




Hierarchy-driven SQL-based Privileges

SQL based analytic privileges (new with SP10)

support to maintain a filter based on a hierarchy node

column

– directly in the SQL section

of the analytic privilege

editor



Analytic Privileges Editor – General Enhancements

Editor UI enhancements

Indication of shared attributes (Property SHARED) in views

Hover over restricted attribute > display secured models

Selected reference model > brushing/highlighting of restricted attributes
