For my production order cuobj field is missing against reservation number in resb due to which my characteristics are not displayed in production order . what could be reasons for these .As it is happening for most of production order .
Thanks in Advance
The configuration is only considered for reservations that are under the individual stock (sales order or project stock). Therefore, you should ensure that the field "individual/collective" is set to 1 in the material master and then test again with a new order.
Another alternative is to manually set the special stock indicator on the order reservation in CO02.
