Dear,

Line Item in Sales Order if the Line Item Quantity is below 100 ,the Line Item Net value becomes Zero

I hope ,it is not possible by standard .You can consult ABAPer on this requirement .If you write any code on this requirement then you have to be maintain above 100 quantity to every line item .If not then you may not be save your sales order .I think ,this requirement will effect on your business process if the  quantity ( 100 ) is not available in time .

Tell me one thing ,why you want this kind of requirement and what is the business process.

Kindly ,let me know if you want further help on this.

Thanks,
