To truly clean house, you didn't need a re-org. You needed RSRV analysis (transaction code) to identify "empty requests" and then RSDD_HDB_DROP_DB_INDEX followed by RSDD_HDB_CREATE_DB_INDEX .
Why page 28 of the underground manuals still matters in the era of BW/4HANA
Page 28 would have scolded you: "Index maintenance is not a monthly job. It is a post-load job." The practical guide’s 28th page probably had a flowchart. On one side: Advanced DSO . On the other: CompositeProvider . In the middle: Open ODS Views . sap bw 7.4 practical guide pdf 28
The fix? Rebuild your CompositeProvider as a HANA Calculation View directly in the HANA Studio (or XSA). Then consume it in BW via an External View.
In BW 3.5 and 7.0, your fact tables (F-fact tables and E-fact tables) were designed to minimize disk I/O for row-based databases like Oracle or DB6. But on HANA, row storage is poison. It destroys parallelization.
Let’s crack open what that page really meant—and why its lessons are more critical today than ever. BW 7.4 was billed as "HANA-powered." But if you migrated an old system, you quickly realized that simply flipping the switch to "HANA-optimized" didn't fix everything. The practical guide on page 28 likely pointed to a single, brutal truth: Your InfoProviders were still physically optimized for row-based storage. Have your own page 28 story from BW 7
Beyond the GUI: Unearthing the Raw Performance Secrets of SAP BW 7.4 (A Deep Dive into the ‘Practical Guide’ Ethos)
Page 28 would show you the dark art of the — specifically, how to convert your cube to "cube merge" mode and enable INMEMORY_AGGREGATION .
Never trust the GUI. Trust M_MVC_TABLES . If the RECORD count in HANA doesn't match the ROWS in SE16 for your fact table, you are already in performance hell. The "Transparent Filter" Lie Another gem likely buried around page 28 of that PDF is the revelation about SID (Surrogate ID) navigation . You needed RSRV analysis (transaction code) to identify
If you see Column Search taking longer than Join Processing , you have a classic 7.4 problem: Your HANA model is emulating a row-store.
Run transaction ST04 (DBACOCKPIT). Look for "High Wait Time on Locks." Then, run RSRT with the technical name of your slowest query. Turn on "HANA Execution Details."
Why? Because the HANA calculation engine would try to union the Active table and the Change Log table for every single query. Over time, your "virtual" provider becomes slower than a standard InfoCube. You might be thinking, "BW 7.4 is out of mainstream maintenance. Why does this matter?"
Page 28 wasn't about the BEx Analyzer or the new CompositeProvider. No. Page 28 was the troubleshooting manifesto . It was the section that taught you how to stop building and start healing .
In older BW releases, the system was brilliant at navigating via SID tables. In 7.4 on HANA, the game changed. The guide would warn you: "Stop forcing HANA to behave like an OLAP processor."
