inspection lot creation for Movement type 531

Dear experts,

following is the procedure

1) Material enter against purchase order SFG

2) Quality checks that and send to unrestricted (its an sampling inspection)

3) Issue this material against production order

4) order is confirmed and GR is done for FG

5) FG material goes to quaity for inspection

6) At the time of inspection of FG it is found that FG is rejected because of vendor material

so we keep that stock in blocked stock. now we create an salvage order by CO07 and issue FG and received SFG vendor material by 531 movement

now my prob is i want to record the defect against vendor material because of which it is rejected and my clint wants the report on reson basis

regards

Sachin
