+This module prevents 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.

+
+Use Cases / Context
+===================
+
+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.
+
+Usage
+=====
+
+To prevent inventory of quants being processed you must check the
+``Stock quant no inventory if being picked`` parameter into the stock
+settings panel. (stock -> configuration -> settings)
+

+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.

+<h1><a class="toc-backref" href="#toc-entry-1">Use Cases / Context</a></h1>
+<p>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.</p>
+<p>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.</p>
+</div>
+<div class="section" id="usage">
+<h1><a class="toc-backref" href="#toc-entry-2">Usage</a></h1>
+<p>To prevent inventory of quants being processed you must check the
+<tt class="docutils literal">Stock quant no inventory if being picked</tt> parameter into the stock
+settings panel. (stock -&gt; configuration -&gt; settings)</p>
