Query BEX - slow - sql statement

Question

Hi to all.
When I execute a query on my master data I see(with the ST05) that the sytem executes a lot of query like that:
SELECT
FROM
  "/BIC/SC_RAG_SOC"
WHERE
  "SID" IN (:A0 ,:A1 ,:A2 ,:A3 ,:A4 )
The SID values are updated 5 for time !!!
Due to the fact that I need to be select almost 500 K of record, can I modify one of the system (database or java) paramenters in order to obtain the following code ?:
SELECT
FROM
  "/BIC/SC_RAG_SOC"
Thank'you in advance

May be first you want to try following:
1. Run Configurator Purge concurrent program which will physically delete all the logically deleted records over the time. You must do this if you haven't done this since long time.
2. Run Gather schema stats on the CZ schema.
If that does not work, then you should upload file SR with explain plan.
