Hello kumar,
1. In my system it is Audit score, I guess in previous versions it was Audit Notes and as its name suggests these are just Audit scores.
2. In target QM sys we have 9001, 9002, 9003; you can also create new target sys.
3. In Actual QM sys we have different QM sys for ISO 9001,9002,9003 with different audit scored etc. and only these Actual sys you get in F4 while maintaining QM system for Vendor.
4. Suppose 1080 is maintained in vendor master record and 9001 in QM material master; if 1080 Actual sys is not assigned to Target Qm system 9001, system will give you an warning or error message as I mentioned in my previous post.
Amol.
