Actually we need to implement CDP Functionality in APO. Now we are CIFing PPM from R/3 to APO for Creating PPM's in APO Side. Since we need to implement CDP we need to change the characteristics values which is transferred from R/3 to APO using specific logic. Which we can see in the Characteristics propogation.
Can any one tell me the user exit or badi to use this. Also please tell me how to do that.
