Bala,
In general, after reading this posting, and your other posting in SD, I would have thought that using /SAPAPO/SDRQCR21 should have made some changes to the orders. Which settings were you using when you ran this program?
For BOP, your settings are probably good enough, unless you have some ATP enhancements, or you have set the Fix-date-qty flag in SD. After hearing how this problem originated, I wouldn't rule out that these problems all were caused by an enhancement or other custom program of some kind in your system.
During BOP, do the discrepant orders you are BOP'ing actually appear in the BOP list?
Best Regards,
