Can anybody please calrify the following for me? Plant A is procuring material X from PlantB via STO. The planned delivery time for the material in plant A is 21 days. The in house production time of the material in plant B is 3 days. When the STO is created, with a delivery date of 04/26/2010, based on the planned delivery time of 21 days, the material has to leave the plant B by 04/05/2010. But what what about the considertation of 3 days of inhouse production tiume in plantB. How does the inhouse production time play in picture?
