Vendor Evaluation not resetting score with GR reversal
I'm testing some functionalities regarding vendor evaluation to implement it, but I'm facing and weird situation. I've set up the main criteria delivery and performed a GR at the right delivery date and quantity, I mean, I've created a PO to 50 units of a material to be delivered on 20.10.2015. On MIGO t-code I've performed the mov type 101 at this date and with the quantity of 100 unit.
Once I did that, my vendor received 100 points, as I expected, however I performed the gr reversal of this document using mov type 102, but the score didn't returned to 0, it is still 100 points. Shouldn't it be reset to 0 points once I reversed the GR?
Vendor evaluation after reversal with 100 points yet.
Thanks a lot in advance.
