Assembly Processing Error

Hi,

When I try to create a sales order for assembly processing, I get

these two errors one after the other and the Sales order creation

terminates. Does Anyone have an idea?

"Error when process Production order"

"Order type PS04 not found(check entry)"

do you know where it's looking for a production order? I don't know

what in the material master or the sales order is triggering this.

I have assigned a requirements type KMPN, requirements class 212,

strategy group 83 in the material master. Sales document type is OR

(Standard Order). I have created a standard network and WBS and

assigned them to the material master in CN08. Is there any other

setting(s) I am missing?

Regards,

Venkat.
