In odoo, you can update the quantity on a quant by filling the counted quantity on the quant form view and clicking on the "Apply inventory" button at the end of the line. Unfortunately, nothing prevents you from doing this for a quant and location in front of which you are standing to perform an inventory while some quantity have already been picked from the location by another user but not yet validated. This can lead to stock discrepancies since the quantity you are updating is not the actual quantity in the location for the system and when the picking will be validated, the system will decrease the quantity you just updated by the quantity that was picked by the other user.
This module prevents this by preventing the user from updating the quantity on a quant if some quantity has been put as done on a move line not yet validated for the same product, location, lot and package.
