    The system is proposing 3 PurRqs because you have three different requirements, and you have selected lotsize of EX. The dates are all the same in the PurReqs because you do not allow start dates in the past. EX means lot-for-lot. 3 requirements generally means 3 proposals (Purchase Reqs). I would normally recommend that you change your lotsize policy, but you have already stated that you don't wish to do that.

    Best Regards,

    are you maintaining any replenishment lead time in material master

    Why system proposes 3 PR?

    reschedule date is different that the reason system created 3 PR

    since the end of replenishment date end on 30 th, system will reschedule the pr based on setting maintained in OPPQ- rescheduling - tolerance value forward

    system will propose the requirement on the requirement date if rescheduling is happening

    on 15 the requirement qty is 20250( reqmt - stock) system proposes rescheduled PR on that date

    0n 18 th requirement is 2750, system create a PR for 18 th

    0n 19 th since you have maintained min lot size as 1500, system proposes 1500 qty on 19 th

    I hope it will clear you doubt
