We just need to override the identifiers for the basic stock report, and you can try to do something like this.
<report string="Picking" id="stock.action_report_picking" model="stock.picking" report_type="qweb-pdf" name="stock.report_picking" file="stock.report_picking" menu="False" />
I have updated information on existing basic inventory identifiers. Report compilation in my custom module.
I hope this will be useful for you .. :)
