Duplicate inspection lot created

Hi All,

While I am creating GR against process order with mvt. type 531(Receipt By Product) there are two inspection lots creating automatically with same batch , material document , process order with same quantity for the selected material and plant. While I see in MB51 there it shows only one movement has taken please with mvt 531 for selected material , plant and batch.

How the duplicate inspection lot is creating automatically for by-product? Please do let me know if you need more information about the process.

Thanks in advance!

With Regard,

NKB
