Here we have a requirement to update the characteristics values for a particular material. Actually now PPM is created through CIF from R/3 to APO. Actually the above said requirement has to be taken care while cifing from R/3 to APO. So any one can help me in giving user exit which has the provision to update the characteristics values while creating PPM. I am not sure the exit can be in R/3 side or APO Side
You can use user exit APOCF023 User-Specific Enhancement of PPM Interface in APO for the required changes.
