Poor performance for the 1st select everyday for AFRU table

81 Views


Hello everyone, I have performance problems with AFRU table. Every day, the first time I run a "Z" transaction, it takes around 100-120 seconds, but the second time and following it only takes four seconds. What could I do, in order to reduce the first execution time?

This is the select:

SELECT * FROM AFRU WHERE MANDT = :A0 AND CATSBELNR = :A1 AND BUDAT = :A2 AND PERNR = :A3 AND STOKZ <> :A4 AND STZHL = :A5

The execution plan for this select takes index AFRU~ZCA with an acceptable cost of 6.319. Index AFRU~ZCA is a nonunique index with these colums: MANDT + CATSBELNR + BUDAT + PERNR

I'll appreciate any ideas.

Thanks in advance,

Santi.
