I want to ask the difference between iw8w and MIGO at internal and external refurbishment process. I know while doing GR, only IW8W can do the Valuation change (From C3 to C2) but i don't have a scenario. So can we use also MIGO at other scenarios ?
My second question, for example i repaired 10 defective spare parts but at iw8w i entered just 1 or less than 10, then where are other spare parts ? How can i follow them ?
