I am working on a integration project. My client is working on assemble to order situation. For production purpose well in advance he procures the materia. For this purpose we used the " Requirement Class" as 45 . We run the t.Codes MD02 and MD04 to create the proudction orders with relation to sales orders. I observed that in proudction order the settlement receiver is "Sales Order". After prodcution order we observed that the production cost price is not updated in the condition type " EK01" . Request any one to help me. As in our case we are in the integration testing phase.
