step by step “subcontracting” process

Dear Experts

Req the experts to comment on the step by step “subcontracting” process :

  1. Outgoing material M1 is with short text and without any material number. What happens in case the material cost = ZERO? Is there any issue?
  2. PR is created as Subcontracting with material code for incoming material M2 (what happens in case the material cost = ZERO material = M2) for which component has gone out as M1 and comes back from subcontracting vendor as M2.
  3. Outgoing material M1  is issued  to SC vendor using standard Mvt type(561)
  4. Can 57F4 document be manually created while component is going out or has to be necessarily thru SAP ?
  5. What is the transaction used to track material issued to SC vendor through standard SAP report for tracking “elapsed “ period
  6. GRN of incoming material M2 is made with material code M2 & follows std. process of Quality Management.  Does the vendor have to return the material with 57F4 back?
  7. How costing module is affected ? How are various A/Cing entries are generated at various stage?
  8. What happens if the  material M1 is NOT given out from the client premises but comes back as incoming material M2. Is 57F$ reqd in such cases and if YES,who will make the 57F4 document ?
