Serial no issue
We have batch management & serial numbers management,
While entering serial no. in sales order-technical objects system is accepting serial no. which is not in stock, like for example, the last serial no. for a material was 200 & that is in stock, but system accepts serial no. 20000 if entered which is not generated and there is no stock for this no. also allows further transactions were also carried out for 20000 serial no.,
By this the serial no were skipped from 200 to 20000, how to restrict this?
