at time of purchase order amend… validation must not increase more than 5% or decrease less than 5%
case1: if i ordered for 5000 units, for what i ordered i received only 4000units (here it showing 10% decrease) system must not take this… it should throw an error like it is not validated.
Case2:in same order if i received 6000 units( 10% more) this also system must not take … it must throw an error as this is not validated.
case3: for the same order if i receive 4500 or 5500 units… which is variation of 5% high or 5% low… this must be validated.
so here my question is … at the time amend… system must not amend quantity more than 5% high or 5% low
