I believe this is the same bug that I have: I have PRODUCTA with qty 7 and prodlot 00001, and I set this product up to track lots.
In a production I use 2 PRODUCTA as raw materials. The production never asks me to enter the lot #s, and then I creates 2 NEW lot numbers for PRODUCTA!!!! So at the end, I have this in inventory: PRODUCTA prodlot 00001, qty 7 PRODUCTA prodlot 00002, qty -1 PRODUCTA prodlot 00003, qty -1 Not pretty! OpenERP cannot just "invent" prodlot #s - it should be either forcing the user to enter a valid prodlot#, or assigning a proper one based on real prodlots and available qtys per location. -- You received this bug notification because you are a member of C2C OERPScenario, which is subscribed to the OpenERP Project Group. https://bugs.launchpad.net/bugs/742613 Title: (6.0) MO: production lot in products to consume Status in OpenERP Modules (addons): Confirmed Bug description: (already reported to support on 06.01.11 / ticket id 3732) set component A in product.form as 'batch handled' create a new MO with BoM which has got product A as component, confirm MO 'consume' component A first issue: production lot is NOT mandantory second issue: with consumption without production lot OpenERP generates new production lots in 'Consumed Products' third issue: after you selected a production lot in 'Products to Consume' this production lot quite often gets lost e.g. after 'scraping' in products to consume.... _______________________________________________ Mailing list: https://launchpad.net/~c2c-oerpscenario Post to : [email protected] Unsubscribe : https://launchpad.net/~c2c-oerpscenario More help : https://help.launchpad.net/ListHelp
