Views)


SAP HANA SPS09 - Modeling Enhancements Calculation Views Enhancements – Transparent Filter Flag

Transparent Filter Flag for stacked views with counters

Enables filter push-down for filtering columns to the lower layer-

view with counter-measures

– Required for filtered, non-projected columns with counters

– Set on every node and column of the upper/consuming calculation view

and on the nodes of the lower calculation/analytic view

Filter column customer is not wrongly

added to the projection list of the query

to the lower layer view with the counter

measure.

Example

"Show the distinct number of

stores where customers John

and Susan have bought the

product Mouse".


SAP HANA SPS09 - Modeling Enhancements Calculation Views Enhancements – Transparent Filter Flag

Correct counter results transparent flag=true.

Incorrect counter results transparent flag=false.

Customer column is added to the

projection list, leading to a different

intermediate set passed into the

upper node.


SAP HANA SPS09 - Modeling Enhancements Calculation Views Enhancements – Re-designing a Scenario

Scenario Re-design – Replacing Nodes or Data Sources

When reusing/refactoring view copies in different context or during

simple re-design of existing view, the flow of the view requires to

exchange or delete nodes or replace a data source

>> without losing the semantic information and mapping in the

consuming upper nodes

– Unmapped column (columns where new data source has no inputs) require

to be removed, mapped to new source or alias

Replacing of Nodes

– replace view nodes with other underlying view nodes

Replacing of Data Sources

– Replace a data source with available data sources in the catalog object,

without losing the semantic information of the changed node. Similarly, they

can also replace a data source in a column view with other available data

sources in the catalog object




Replacing of consumed Data Sources

– Replace a data source with available data sources in the catalog object,

without losing the semantic information of the changed node. Similarly, they

can also replace a data source in a column view with other available data

sources in the catalog object




Replacing of consumed Data Sources

– Unmapped column (columns where new data source has no inputs) require

to be removed, mapped to new source or alias

Handling unmapped columns




Replacing of Data Sources/Node references within a intermediate node

– Replace a data source with available data sources in the catalog object, without

losing the semantic information of the changed node. Similarly, they can also

replace a data source in a column view with other available data sources in the

catalog object




Replacing of Nodes

– replace view nodes with other underlying view nodes

– Delete intermediate node (e.g. projection)

– Replace Node with a data source

Unmapped column (columns where new

data source has no inputs) require to be

removed, mapped to new source or

alias


SAP HANA SPS09 - Modeling Enhancements Calculation Views Enhancements – Enabling Query Results Cache

Enabling query results caching control

Using query cache

– Query cache is only used for complex queries (group by …)

– Suitable to use read-mostly workload, same set of queries is executed

repeatedly, rather non-changing data, rather expensive queries

e.g. Smart Data Access queries

Time-based control view- property, when query cached shall be

invalidated

– A time-based cache invalidation property (advanced view properties),

which invalidates or removes data from the cache after the specified

time interval.

Reviewing chache use.


SAP HANA SPS09 - Modeling Enhancements Calculation Views – Miscellaneous Enhancements

Miscellaneous Calculation View Enhancements

Attribute Keep-Flag additionally to Aggregation-Nodes is now also supported with Projection-Nodes.

– It indicates that the attribute is kept during instantiation and execution of calculation view query for a node and is passed

on to the upper nodes even if it is not requested by the query (~must use attribute).

Star Joins - Top Calculation View-node switch from/to Star Join-Node now supported

Star Joins – now support referential join conditions

Time-Dimension Calculation View now supported

– ~ to Attribute View-type Time-Dimension

Managing Schema Mapping Enhancements

Schema content may derive from multiple / different

back-end or authoring environments

*In order to ease managing of schema mapping in

such scenarios, package-specific schema mapping

(which overrides the default schema mapping) can be

maintained in _SYS_BI.M_Package_Default_Schema

New UI dialog

– Users can use the new UI in SAP HANA modeler to

maintain package specific default schema. This replaces

the manual process of using SQL statements to maintain

package specific default schema in the table

M_PACKAGE_DEFAULT_SCHEMA (Schema: _SYS_BI).

*Introduced with HANA SPS08

The default schema mapping is overruled by

Package-specific Schema Mapping
