co-products independent requirements

[Former Member]

Hello gurus,

Here is the situation: The client starts a production order without knowing what products they are going to produce, so the BOMs include many co-products.

So when i am planning independent requirements (MD61) for those co-products, later, the MRP suggests planned orders for those co-products, wich i can't convert (and dont want that). I wanted to know if it's possible to suggest planned orders for the main material of the production order, taking into account the co-product quantities planned in independent requirements.

Sorry about the bad english

Best Regards,

Create a Perfect BOM for main Material and add the list of coproduct which is getting generated during Header material as Negative quantity in line item along with consuption ( raw) material..

In main MAterial tick the coproduct indicator In Material master

Tick coproduct indicator for all the Coproduct material in Material master & in The line item of the in BOM.

Create a plan for header material in MD61. & run the MRP, Sytem will create a plan order for header material only. for All Coproducts system will create a dependent requirement,

When you do the GR against the production order , System will propose the main material & coproduct material with movt type 101.

Thank you for the fast reply Sundaresan

I am sorry, but thats exactly what i have done until now.

I wonder if its possible to place some independent requirements for the co-products and instead of sugesting planned orders for the co-products it sugests for the main material.

Thanks,

Hi,

I am unable to understand the business process you are following. A co-product is produced along with the main material & does not require a special planning.

Hence before proceeding with any solutions, can you let us know the business need to do something like this?

Hello,

This business envolves the production and transformation of codfish. But the factory starts the processes without knowing wich final products they are going to produce. This decision envolves many factors like quality, weigh... So we opted to include the possible final products as co-products in the BOM. As they can produce many final products, making a production order to each one would be too much work for the responsible person. At the order confirmation they can choose wich products and quantities they produced.

I was constructing a simulation with the processes and wanted to know if there is a reliable simple MRP planning for this situation.

Once again sorry about the english.

Best regards,

Hi,

At the outset you dont have to be sorry about your english, it is just a language which is used to communicate & i am quite sure none of us are so perfect in it.

A suggestion which i can give (test this in your sandbox first).

- Create a dummy material with material type UNBW, so that it is non-valuated.

- Create a BOM for this dummy material where-in all your CODFISH are defined as co-product with the expected production qty

- Maintain the equivalence numbers & settlement profiles for the co-products such that the entire cost is distributed to the co-products & no cost is accrued to the parent material.

- Create an order for the dummy material & in the component list, you can change the qty of the co-products that you expect to produce.

- At the time of GI of co-products specify the exact qty that is produced so that you can receive the same in stock via 531 movement type.

- Post GR for the dummy material at the end of the order, this will only increase the stock qty but will not hit the financial books, you can then decide to either scrap this or keep them as dummy stock.

- If the dummy material concept is not acceptable by business, then create an order via co07, then you will not need any dummy material.

- Check the postings both in terms of logistics flow & also in-terms of financials i.e. cost

Since you're not sure at the begining of production what is being produced & also business is not ready to create an order for each final product, it is very hard to go for any kind of planning as such.

Test & see if the above can meet your need.

Thank you Vivek,

I think your suggestion will be very helpful.

And yes, as for the planning i think will be a bit hard to do under these conditions, so i am closing the post as answered.

hi Helder,

when you have byproduct/co product in the Prd order for header material.

it create a DepReq for coporduct/byprd material, but if you see this element properly its not -ve (its +ve) so basicallly its not a requirement element its a receipt element.

so if your PIR less than the receipt element total, it will not create any planned order.

and as u said it wont allow you to convert the planned order. this is good (even u wanted that).

why you want the system to propose the header planned order??

and imp question is why are you putting PIR for co product?? this is senseless. to me... or please explain the busines where such requirement can come..may be i am not aware about this.
