When you start thinking of changing your concept in the code please think of changing the terminolgy as well: not only in Food, chemical and pharma manufacturing industry we are talking about batches instead of lots, true?
Yes, it's true: in all ERP systems I've ever worked in (even if I just had a look at them): you have to enable/disable ONE parameter to set a product batch handled or not. And if you enabled this parameter the software guarantees that NO stock move could be validated without assigning a batch. @Nhomar: this is not just a claim in food industry. Even for manufacturing brake linings we have to ensure a full traceability, including material sent to subcontractors and its usage in finished goods in China. We reported a few bugs about this issue - still waiting for answers (and it does not sound very promising when you find out your bug is set to 'whishlist') If OpenERP still pursures the strategy to become one of the top 10 ERP providers (and I really would appreciate this!) you quite soon should start reviewing the philosophy in stock management and manufacturing It would be fair enough to let us know about the descisions made by OpenERP.... -- 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/670451 Title: [trunk][stock and mrp] LOT traceability is broken Status in OpenERP Modules (addons): Opinion Status in OpenERP Addons 5.0 series: Confirmed Status in OpenERP Addons trunk series: Opinion Bug description: Product traceability works only in the simplest cases: When You buy product and sell them from the same location. But if internal moves or manufacturing operations are involved then traceability can't be guaranteed or even impossible. The one single reason for this is that there is no way to set "Tracking moves between physical locations" on products. You can track only incoming, outgoing and manufacturing LOTs: The ones from and to virtual locations but not between physical locations. Doing internal moves the system don't force the usage of LOTs even if all tracking options is checked for a product. The worst case is when You use mrp module for managing Manufacturing operations: Two sets of stock.move object is generated when You click on "Confirm Production" in a Manufacturing Order. One set is for Consuming Products on which You are forced to set LOTs (when "tracking manufacturing LOTs" option is checked on the product). The other set of stock.move object (a picking list) is done behind the scenes. Since these (hidden) moves are internal moves and done automatically LOT assignment is not forced. The effect is that the system moves the raw materials from Stock to the Work Center Location without LOT. Then when the user tries to set LOTs on the products to consume (from the Work Center Location to the virtual Production location) a warning message is shown: "Bad LOT assignation. You are moving 5 products but only 0 available in this lot." The available quantity turns to negative and the shortage is increasing by every Manufacturing Order. The work around is to set the LOTs on both the products to consume and the internal picking list. But it's not forced by the system (so no guarantied) and is even a lot of unnecessary work. Imagine to do it on 20 ingredients: 2x20=40 LOT assignment. You have to set the same LOT on every two related moves one by one. Double work for nothing to gain. But certainly it's not intuitive. Anyway I don't understand why are there 3 options for tracking LOTs? And it's even don't cover all the possibilities. So either there should be a 4th option to track internal moves or there should be only one to track all moves for a LOT (as in some other ERP systems) As I know LOT tracking is for traceability. So what is the purpose of the possibility of partial LOT tracking? (only incoming or only outgoing) What useful information can You get from them? For product traceability You need to track all LOT moves. While OpenERP is a promising product it's not yet usable in Food, chemical and pharma manufacturing industry where LOT management and full traceability is vital. In essence two development would be needed: 1. Ability to track internal moves (Preferably with one single option on products for all LOT tracking) 2. In Manufacturing orders to automatically copy the LOT attribute from the products to be consumed to the internal picking list. (So that the user should not have to repeat the LOT assignment and tracking would be guarantied) _______________________________________________ Mailing list: https://launchpad.net/~c2c-oerpscenario Post to : [email protected] Unsubscribe : https://launchpad.net/~c2c-oerpscenario More help : https://help.launchpad.net/ListHelp
