Hi,
While confirming the production order the valuation type which is specified for the child item or the header item the system should pick it automatically from the material master that is defined.
Here we have two cases if the valuation type is only one for the material then that has to be picked up automatically.
In the other case if it is more than one then on the priority it should pick is there any customization to define the setup.
