Work confirmation setup - Piece picking

Hi everybody!

During picking with mobile device, the work confimation is set to Location confirmation, Product and Piece picking confirmation.

The scenario is:

a. 5 units product AAA, size S to be picked from the same location
b. The warehouse worker arrives, confirm location OK
c. Tooks one product, confirm product scanning bar code OK
d. Scan again one item product AAA size S, picked qty=1 OK
e. Scan again one item product AAA size XS (mixed item by mistake inside the location), picked qty=2  --variant is not validated
f. Next 3 units are picked and the work is closed without error messages

As far as it is the same product, other variants are considered as valid by the mobile device in this scenario.

Can anyone confirm if Piece picking should be capable of doing such validation?
