Prevent User entering wrong Price in BPA

In the Price Break lines of BPA users were entering wrong values which were impacting the price in POs and releases from which wrong invoices are resulted.

Some steps that we took are like providing alert whenever the Price deviation is more than a set value like 5%. Thats when the Authorized user who gets the alert immediately checks and does the correction if needed.

In this way, the errors of huge values are corrected to some extent. But the issue is still high when the price deviation is small and wrong, but the item quantity purchased is huge. This was still resulting in to huge loss.
