I know this standard method; it doesn't work for stock moves that are in a "waiting state for another movement" status; I need first to cancel the move; this where it takes around 20 seconds per transaction and I got several hundres to cance. That is why I asked for an advanced way of dealing with such a mess.

Anyway thanks for having answered.

Ok , then you can write a sql query and update the db directly . Or just write a python code for the same and run it.

AS I don't have access to the db thru a sql query (Odoo Saas), what would be the python code process: a button acting on a list of moves? in this case what would be the coding?

Would you please provide me with such coding (I am not a developper)?

something like below?

context = context or {}

for record in self.browse(cr, uid, context.get('active_ids', []), context=context):

value = "waiting for another move"

for val in [state "from stock move model":]

if val:

value += "cancelled" % val

pool.get('product.template').write(cr, uid, record.id, {'state': value[:-1]}, context=context)
