When attempting to process a specific work order I am getting an error.

I am unsure how precision rounding is causing an issue with the work order/manufacturing order. It has been submitted to the Odoo bug team but since they have been quite busy for the last few weeks I thought I would check if anyone here has any tips.


Thanks in advance.


The error can be seen below.

The error ended up being unrelated to precision rounding but was caused earlier and wasn't caught until the rounding function.

Location of Error

File "/home/odoo/src/odoo/addons/mrp/models/mrp_abstract_workorder.py", line 273, in _update_finished_move

production_move = self.production_id.move_finished_ids.filtered(
            lambda move: move.product_id == self.product_id and
            move.state not in ('done', 'cancel')
        )

The problem

In the above lambda statement move.product_id was returning the id of the originally selected product which had since been changed so it was being compared to self.product_id which was a different product. The odd part was that in the Odoo interface there was no indication of this issue as everything looked like it was updated to the new product.


My Solution

Not the ideal solution, but I ran a one time scheduled task and updated the finished_product_id to match the new product id.

precision_rounding should be 0.01 not zero

I looked at it appears that all of the products units of measurement have their round set to 0.01 with a few being at 0.001 so the problem may be somewhere else instead?

You need to audit these files

File "/home/odoo/src/odoo/addons/mrp/models/mrp_workorder.py", line 412, in record_production

self._update_finished_move()

File "/home/odoo/src/odoo/addons/mrp/models/mrp_abstract_workorder.py", line 273, in _update_finished_move

float_round(self.qty_producing, precision_rounding=rounding)
