Hi Asvin,
I have compared objects and found that the field QMFE-ANZFEHLER provides the value of 'Number of defects' (in ECC) . Similar field ZHLPROBL is found in 2LIS_05_Q0ITEM. I can not confirm as data is not available.It would be helpful if by comparing data it can be confirmed that the value of ZHLPROBL comes from QMFE-ANZFEHLER.
Regards,
Sangarsh
