Goal

On RMB v2.4.0.1.0 against FW v4.2.0.3, during BILLING batch run, the following statement is doing more than 8 million executions and every time returning 0 records:

SELECT BS.BSEG_ID, SAT.BI_PROC_SEQ, SA.SA_ID FROM CI_BSEG BS, CI_SA SA, CI_SA_TYPE SAT WHERE BS.BILL_ID = :1 AND BS.MASTER_BSEG_ID = :2 AND SA.SA_ID = BS.SA_ID AND SAT.CIS_DIVISION = SA.CIS_DIVISION AND SAT.SA_TYPE_CD = SA.SA_TYPE_CD ORDER BY SAT.BI_PROC_SEQ , SA.SA_ID /* SQL for COBOL program 'CIPBBSGF', SQL name 'S_SUBBS' */

The statement queries for sub bill segments for each of the bill segments generated.

This article provides guidance on how to turn off the feature to suppress this problematic SQL or be removed from the BILLING processing as it causes unnecessary performance degradation to the batch job. This affects production where the job is at risk for not completing within the expected time frame for slower performance.
