Sap Bw 7.4 Practical Guide Pdf 28 <2024-2026>

Now go check your RSDD_HDB logs. You’ll probably find an index that hasn’t been rebuilt since 2018.

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.

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 would show you the dark art of the — specifically, how to convert your cube to "cube merge" mode and enable INMEMORY_AGGREGATION . sap bw 7.4 practical guide pdf 28

Here is the deep technical reality that most architects ignored:

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.

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 . Now go check your RSDD_HDB logs

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 page 28 of the underground manuals still matters in the era of BW/4HANA

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. But on HANA, row storage is poison

Why? Because HANA’s optimizer relies on fresh statistics. If your stats were from the last system copy three months ago, HANA would generate a brilliant execution plan for a dataset that no longer existed. You’d see a query take 12 seconds that should take 200 milliseconds.

For years, a quiet, dog-eared document circulated among senior BW consultants: a PDF simply titled "SAP BW 7.4 Practical Guide." And within that guide, was the threshold.

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.
