Immediate Action:
1) We have checked and stock parts and no parts found in FG(Finished Goods).
2) We have checked the WIP parts and parts in 1st stage and informed to engineering department and they will take necessary action in the final finishing stage. 

Root Cause:
1) Scratch mark noticed during transit that is removed by bench work with rotary scarfing.
2) Surface finish is within Ra3.2 but that surface looks like uneven after surface treatment.
