[trunk][mrp] stock_move.action_consume raises exception

[Tamás Dénes]

In the mrp modul's Manufacturing Order form clicking on the "Produce" then the "Confirm" buttons raises an AttributeError exception with the message 'stock.move' object has no attribute 'split_lines'. This occurs only if there are raw materials in the BOM list on which the "Track Manufacturing Lots" attribute is checked.
The problem seems to be the result of some untested and incomplete refactoring. (Probably at revision 3038.1.7)

The traceback is as follows:

Hello Tamas Denes,

Would you please provide me more information with proper steps to
reproduce this at my end?

Thanks

I confirm the bug, split_lines is nowhere in the code. I think it's action_split instead of split_lines.

HelloTamás Dénes

Thanks for reporting,
It has been fixed inlp:~openerp-dev/openobject-addons/ron-dev-addons2

Revision num: 5044.
It will be available in trunk soon,

I've just checked this function since it has been fixed. I found that this patch solved the problem reported above but introduced two new ones.

The new problems are:

1. After consuming the raw materials they appear in the right side list doubled. (Every item is displayed twice in Consumed Products). Initially the duplicated lines show only a quantity of 0 but after double clicking on any line the duplicates will be shown.

2. A new LOT is generated for each consumed raw material after invoking consume. So the system wants to consume materials from such LOTs where there is 0 quantity in stock. These new LOTs will have a negative stock quantity and these LOTs are used for nothing. At the same time stock quantities in the work center locations keep increasing because the user sets the right LOTs on the Internal Moves lines but the system doesn't consume raw materials from these LOTs.

The mechanism mentioned in the second problem should be changed so that Production LOT should not be generated for the Consumed Products but should the LOTs copied from the Internal Move lines (Picking List). This way the system would work as intended.

I've committed the bugreport #691012 with the problems mentioned above.
