Remodeling Toolbox – Positioning

Remodeling Adjust data model to new business requirements or strategies Scenarios

A new key figure must be added to a particular InfoCube (that can also be initialized)

A new characteristic should be inserted and may replace an existing one. It can be filled based on the old characteristic.


Remodeling Toolbox – Capabilities

Remodeling Remodelling Rule

Collects remodelling steps for a particular Info Cube

Characteristic Conversions Add / Replace Characteristic initially filled with

Constant (e.g. dummy characteristic value) Attribute of an Info Object of the same dimension The same value of another Info Object of the same dimension Customer exit (for customer-specific coding of the initial value)

Delete Characteristic

Key Figure Conversions Add key figure initially filled with

Constant (e.g. ‘0’) Customer exit (for customer-specific coding of the initial value)

Replace key figure Customer exit (for customer-specific coding of the initial value)

Delete key figure


Remodeling Toolbox – Impact

Impact During the conversion process, reading (querying) and changing the

InfoCube is locked All depending objects (queries, transformations, MultiProviders etc.)

will be deactivated and have to be adjusted manually Aggregates and BI accelerator indexes must be rebuilt after the

conversion

Authorization Same authorization objects apply as for the InfoCube maintenance

OSS component BW-WHM-DBA-RMT

Remodeling Toolbox – Creating Remodeling Rule

Remodeling Rule Consists of one or more

operations (like adding ordeleting a key figure etc.)


Remodeling Toolbox – Characteristic Conversions


Remodeling Toolbox – Key Figure Conversions


Remodeling Toolbox – User Exits – 1 –

Implementing Customer Exits Implementation of customer-specific class

in class builder (transaction SE24)



Implementing Customer Exits Use Interface IF_RSCNV_EXIT



Parameter Three parameters are given

I_CNVTABNM: name of the table that will be converted (in case you need one remodeling rule for more than one InfoCube)

I_R_OLD: structure of the table before the conversion C_R_NEWFIELD: result of the routine which will be assigned to the new

field



All classes that implement the interface IF_RSCNV_EXIT will be available in the F4-help.

Overview




Remodeling Toolbox – Scheduling

Scheduling Schedule the remodeling rule or start it immediately

Periodic scheduling not useful

Parallel execution Supervising job splits and controls (background) processes for parallel

table conversions Currently: only one single process is started in the parallel mode Recommendation: do not flag the parallel setting if you might have

system constraints (or for debugging purposes)


Remodeling Toolbox – Monitoring

Monitoring All steps logged with detailed information


Remodeling Toolbox – Outlook

Outlook Transporting remodeling rules Remodeling for InfoObjects (e.g. adding compounding) and

DataStore Objects Performance enhancements: full parallelism of database

conversions
