I have come across one problem in MTO scenario.
When we convert planned order into Prod. order with respective to sales order then in assignment tab page of Prod. order system allows us to change sales order no. with another sales order no for same material.
We are using strategy 50 in this case. please let me know why it is allowing to do so as in MTO it should be always in display mode. In gernal data tab page it is in display mode.
Thanks in advance for your valuable input
