  • BW – Issues & Challenges• Loss of credibility – No faith in BW, increase in offline/non BW reporting• Reporting Runtimes – As the amount of data increased, so did the report runtimes• Data Loading – The daily load amounts stayed the same, but the time taken for the updates to complete was constantly increasing• Tablespace – constantly having to increase table space volumes month on month• Inherited Bad Practice – Lack of housekeeping, cube design, lack of Data Store Object’s
  • B.I. PerformancePlan for resolution of issues was created based on Best PracticeStrategy recommended by De Villiers WaltonSplit in to two separate phases of workPhase 1 – Best Practice StrategyPhase 2 – InfoCube Redesign 9
  • B.I. PerformancePhase 1 – Best Practice Strategy• Aggregates• Compression• Scheduled Jobs – PSA / Change Log / Compression• Process chains updated and reordered for better data loading• Deletion of dormant InfoCubes / Queries Reduced data usage from 98% capacity to 64% 10
  • B.I. Performance – Aggregates 11
  • B.I. Performance – Compression 12
  • B.I. Performance – Process ChainsClear Out PSAClear Out Change Logs 14
  • BW Performance – Phase IIPhase 2 - InfoCube Redesign Multiproviders – Ensuring that all cubes have a multiprovider over them SAP_INFOCUBE_DESIGNS – 9 InfoCubes identified for redesign Redesign – change of cube structure/storing of data Indexing – Indexes added to improve performance of InfoCube Partitioning – Cubes partitioned by fiscal periods InfoCubes by Year – Each cube designed to hold one fiscal year only Report movement from InfoCube to multiprovider Reloading of data to redesigned InfoCube 15
  • B.I. Performance – MultiProviders 16
  • B.I. Performance – SAP_INFOCUBE_DESIGNSShows the database tables of an InfoCube, the number of records inthese tables and the ratio of the dimension table size to the Fact tablesize.  If dimension tables are too large then they can cause badly performing table joins on database level. As the data volume grows and the data allocation changes over the time, this check should be executed regularly.  When loading transaction data, IDs have to be generated in the dimension table for the entries. If you do have a large dimension, this number range operation can negatively affect performance. 17

  • BW Performance – Benefits RealisedIncreased query performance  Average query runtime down from 20 secs to 5 secs  Average database call time down from 12.5 to 3 secs  Examples, Sales v Budget report 15 secs down to 5 secs Gross Margin reports 30 secs down to 3 secs Debtors Analysis 60 secs down to 6 secsIncreased tablespace capacity – was 98% usage, now 60% usageImproved data load time – Recent load of a cube took 60 hours, aftercube redesign was down to 6 hours (excess 20 million record – highlycustomised)User Acceptance – Improved performance leading to satisfied usersrunning reports quickly and efficiently - now getting the data theywant in a timely manner.
  • BW Performance – Benefits RealisedAccuracy – “One version of the truth” – reduction in offline reporting,reversion back to centralised report structure. Business is nowbenefiting from quick and accurate reporting.Credibility – No longer a question over the availability or the accuracyof the data. People can now rely on their reports being there andbeing accurateDowntime – Outages now restricted to unforeseen errors (oftencaused by end users). Outage resolution a lot faster due to theincrease of system performance, full weekends no longer required forreloads.
