Supplier capacity

Can AX 2012 capture supplier capacity data?  If so can this be fed into MRP?

Thanks,

Rosey

    Hi Rosey,

    What do you mean with supplier capacity data? Is it the on hand at the vendor?

    This is not supported. MRP calculates your requirement. If the vendor cannot fulfill, you can search for another vendor or probably you also have to postpone your sales orders.

    It is not in your control, so how would you define capacity? You could reflect this as a resource and set the capacity, but you don't control it!

    RE: Supplier capacity

    Hello Steven, maybe I'm thinking in the wrong direction but I can´t think of anything else how we could help our customer.

    Our example is, that we have an agreement with our Vendor to order a maximum quantity of Item group A + a maximum quantity of Item group B at once in one purchase order. Less is Ok, we only have to avoid exceeding the agreed maximum quantity.

    The question is if there is any way to make sure that the MRP accumulates the planned purchase orders in bulks of these maximum quantitys by item group. (I wouldn´t mind to set it up item by item if nessesary)

    You could probably use sub contracting for this purpose and add x amount of resources for how many products that can be at the vendor at one time. Use a resource calendar with your lead time intervals and open just one day to schedule them at the same time...

    Hi, There is no way to do that in AX the way you described. Although sounds quite straight forward, the problem is that MRP  is always thinking item by item and is not aware of any grouping (many good reasons to that I'm affraid). Customization for this would be quite simple however. Additional validations would need to be run on firming, performing the logic you presented. Still the whole proces would still be semi manual - too many subjective things to decide, like the simplest example: if we exceed the agreed quantity, which item do we want to skip...? Or maybe we want to reduce quantities on some items, in order to have other items fit into this order... This and many more questions would need to be managed manually by the buyer.

    Maybe you could make these items into one item with multiple configurations? That might do the trick...

    In principle there could be more than two such items.

    So the challenge is to set a maximum quantity of a variable assortment, (which may not even be variants of the same item.) within a specific time.

    Interesting, and not supported, but I can see uses for it including: shipping space and storage space planning. It raises some thorny operational questions:

    • From an mrp point of view its going to want to satisfy demand, so how does splitting supply into two orders help solve the capacity problem?
    • What is the acceptable time gap between successive orders?.
    • What are the rules for accepting a sales order quantity - for what time period? -  what will you accept/promise?  Who makes that call? Salesman, Sales Admin, Master scheduler? Buyer? 
    • How will you manage the constraint across multiple orders and products?
    • If you accept the sales order then do you expect mrp to plan supply accordingly and to give expedite /redate omessages to meet promised dates and quantities, or to advise to redate the sales order?
    • Do you use such constraints in your forecast?
    • Are there alternative vendors?
    • Alternative items?
    • Can capacity be varied, if you give additional lead time e.g. for extra shifts/or overtime working?
    • Does the vendor have any other demands on the same capacity?
    • Are these traded items, or are they used in BOMS/formulas and if so then what is the impact on the planning of other items?

    I suspect the rules, and priorities will change from day today, and that at least some manual review and scheduling will be needed - maybe an Excel dump of your Planned orders.

    I did a small amendment to the planned orders view for a customer that included price and weight in addition to purchase order standard quantities, minimum, max and multiple.

    This gave them ample opportunity to gain quick insight into what orders they should group to maximize vendor transport fees and rates.

    Thank´s to everyone for the answers.

    It almost seems like the only way to do this right would be by adding another entity with the vendors resources and do some sort of intercompany order/sub contracting/capacity planning "octopus". That's extra effort overkill of course and I'm not sure if this would even work out but it still would be interesting to know.

    As magic1949 suggested, we will use an cube to create an excel report that takes the transactions of all these items into account and compare them with fixed capacity frames, as soon as one some item reach the maximum the planner has to step in and make manual decisions, I think that's reasonable enough.

    Fun fact: I actually just did the same thing, I see myself doing this again unless MS decides to include this in the standard.
