Now go check your RSDD_HDB logs. You’ll probably find an index that hasn’t been rebuilt since 2018.
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.
It had one foot in the legacy world of transparent tables, aggregate rollups, and process chains that looked like spaghetti. And its other foot was firmly planted in the future—in-memory computing, columnar storage, and the promise of "instant" reporting.
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." sap bw 7.4 practical guide pdf 28
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 .
The deep insight? The BIA INDEX (the legacy accelerator) was dead. In its place, HANA calculated views. But if you used standard MultiProviders or Infocubes (yes, people still used Infocubes in 7.4), you were forcing HANA to emulate a bitmap index.
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?" Now go check your RSDD_HDB logs
Page 28 would show you the dark art of the — specifically, how to convert your cube to "cube merge" mode and enable INMEMORY_AGGREGATION .
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.
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 . It had one foot in the legacy world

But here is the practical kicker that most blogs missed: Even after conversion, your F table still contained REQUEST_GUID entries for every single data load. That’s right—every DTP request left a forensic trail inside the fact table.
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 .
