Reply from PedroT on Feb 23 at 10:32 AM Didn't understand. That is one of my questions.
From what I understand, it is the weight in the DB, and that can be diminuished by creating a index.

Subject: DB01 - Index Analysis Explained
Hi,
I'm checking the tables wich SQL server recommends new indexes in SAP.
This is in Db01->Indexes--> Index Analysis.
There are some columns:
Load, Avg Ucost, that I understand, but there are 3 that I'm trying to understand
Columns contributing to equality predicates
Inequality
Column needed as covering columns
I have something like:
Table name:MSEG
Load: 500,390
Avg ucost:1,237.3503
%benefit : 83.04
Queries: 487
Columns contributing to equality predicates: MANDT
Inequality:BWART
Column needed as covering columns: MBLNR, ZEILE, MATNR, WERKS, LGORT, CHARG, INSMK, SOBKZ, KUNNR, KDAUF, KDPOS, SHKZG, BWTAR, MENGE, MEINS, BUKRS
Who can explain what kind of index do I need?
What is a valid load to start thinking about creating an index?
Regards,
Pedro |
