Hi Thanks for your reply. But my sales order having two line item.
one line item having item category TAN.
Another one ZTNB . There is exit which put the sales order in delivery block in schedule line when saving the order.
But for this ZTNB item category line item sales order always gets stuck in MD04. We have checked in other system.
We have to remove it through the report SDRQCR21.
Do you have idea why this item category line item always gets stucked in MD04?
