Produce several MOs at once, best practice

Hi, I'm wondering about the best approach for the following scenario:

We produce lollies in different sizes and tastes. We'd like Odoo to take stock into account and create draft MOs automatically. The challenge lies in the fact that we produce different sizes (different products) in one production run, since they obviously have the same flavour.

I do know of the approach with by-products. However, that approach has also a downside.

It doesn't show how many S, M, L or XL lollies the employee should make, but works fine for tracking the production.

The other approach I tried was to produce some kind of raw candy mass in Odoo. However, that doesn't take into account that the boiling hot candy can not exactly be put on the shelf and be used later and needs to follow certain maximum or minimum batch sizes. This way it merges MO requirements in a way no average employee can easily track.

So to make the problems at hand clear, the employee should see easily two things:

A: What rawmass they should prepare (flavour, mixture, colouring, etc.)

B: What exact amounts of each product should be produced from it.

Otherwise the approach is I check the inventory manually and create MOs accordingly.

Any advice is greatly appreciated. Thanks in advance guys :)

Hi,

It does seem like you can use the by-products, BOM does capture the qty of by-product and you can also have multiple by-products.

The limitation is that the by-product can't be manually modified as it would be in the ratio to product as defined in BOM, also on automated replenishment the MO is in confirmed stage preventing any edits.

e.g if the BOM of XL is defined as - qty to produce is 1. with L, M & S as by-product with qty 1, .8 & .5.. then a batch of 10 XL would 10L, 8M, 5S

If you need replenishment to be automated. you might have create BOMs for all products L, M & S ; with the other 3 as by-products. You could also create multiple BOMs for a product with varying % of by-products, however am certain how the BOM is selected on automated replenishment process

Essentially every MO would produce 4 variants in a fixed ratio

The limitation however is that inventory replenishment would kick-off MOs for each product as it does not take into account any by-products which are already part of a MO. e.g if both XL and S are below the minimum, 2 MOs would be generated while only 1 MO would have sufficed for replenishing the stock of both products.

A manual check would be required to cancel multiples

Hope this helps!

Hi, first of all thank you for your answer :)

In fact I was able to edit the quantities of by-products produced! So the production side itself is perfectly able to replicate the real world. Only the automated replenishment side is missing. I can not really imagine no one having this problem before, as there are many companies working with a raw mass that then is used to fulfill many orders at once (casting metal or concrete or dough in a bakery for example). But it seems that this will require manual checking and the creation of MOs every day.

But that brings up a new problem. All the production needs to happen via by products, since tracking the batch is especially important with food. So my only solution is to write a note in the MO "hey we need this amount of that size"

But still, thanks for the help and best regards.

Thanks Marvin,

Yes, achieving a MO without manual intervention doesn't seem possible.

You can update an MO with the quantities (product, by-product & components) on manual creation or if MO in draft stage. In the confirmed stage you can update by-product and component qty. So, you might rather update these quantities on the MO directly rather than in log/note.

Considerations:

Since the automated replenishment creates the MO in "Confirmed' stage, you might want your component qty in BOM to be set-up in a way that a batch of product to produce creates a batch of raw mass and not a part of it.

Also, tracking a lot/ batch is possible even for by-products, if you need to track raw mass then you might need set it up as a sub-BOM

Unfortunately, it doesn't seem like a lot of help from where you already are!

My choice would have been to use multilevel BOMs. You set up a first level to produce a raw mass. Then this mass is used as a component for producing the finished lollies. Set up with reordering rules where min / max = 0 for each product, or min / max stock only for the finish lollies.

The production order for raw mass, will be the total qty required for sum of all lollies. You will have several manufacturing orders to confirm, but this will give much better control than using By-products.

There might be challenge on when to run the scheduler. And you might get the situation that you only need one of the lollies sizes, and not the others. So some manual check of the manufacturing orders will be necessary.

Use Lot number on all products, for tracing.
