Support for Recycled By-products in AX 2012 R3 CU8
This new functionality is available with KB 2989470 / HF 2989470 and will be included in Microsoft Dynamics AX2012 R3 CU8. To find the HF you can use LCS Issue Search.
To support recycled or recurrent products in process industry, it is now possible to use the same product as both input and output on a formula. As an example, this is useful in plastic molding where consumed plastic regrind can be recovered from the manufacturing process. Other examples are processes where you put metal scrap from the stamping/forming process in a foundry.
The recurring co-product solution in Microsoft Dynamics AX2009 had some limitations on the costing side and was not ported to AX2012. This new solution use by-products with a stronger support for costing.
This new feature enables the consumption and reuse of the same by-products in the production of formulas and batch orders, by allowing BOM circularity for output that has the production type, By-product.
For costing purposes a new Burden type, Recycled, was added to handle the cost of the recycled by-products. Use of the Recycled Burden type deducts the joint production cost that is allocated to the formula and co-products, by using the standard cost value of the recovered by-product.
By-product output from planned and firmed batch orders is ignored during planning. This is done to ensure that demand for the recycled product isn't pegged against by-product output from the same order, or other orders from the same process or BOM chain. This means that the recycled by-product cannot be pegged until it is on-hand (posted from the batch order).
Finally as a small additional improvement on the Explosion form, it is now indicated when a formula output is a by-product. This is done by adding '(By-product)' to the line.
Set up recycled by-products
In order to allow BOM circularity, the recycled item must use standard cost and use the production type By-product or in special cases Co-product. On the formula the recycled product input is a normal formula line, and the output on the same or other formulas is a co-product output of the Production type, By-product, and the Burden type, Recycled.
Ensure that the Production type is By-product on the Engineer FastTab for the product:
Note: Products with production type Co-product can also be used, but then you will have to change the Production type to By-product on the formula or batch order, to use the recycled by-product functionality.
Output - formula producing the recycled product
On the formula (can be the input, or another formula) that produces the recycled item, the recycled item must be added as a co-product output of the production type, By-product, with the Burden type, Recycled:
We are aware that the name Burden is not full correct with the Recycled option added. However, the nature of a hotfix release didn't leave room for renaming.
Let's try an example to see the feature in action:
We have the following three products:
M1 - Main ingredient, Standard cost - $10/Kg, Purchase, 100 kg On-hand
B1 - By Product, Standard cost - $5/Kg, Purchase, 15 kg On-hand
F1 - Formula item, Standard cost, Production, 0 kg On-hand
To produce F1 we use the following formula:
F1-FORM, Formula Size: 10 Kg
With the following lines
M1, 20 kg
B1, 10 Kg
First sales order
To generate a demand for F1 let’s create a sales order for 10 kg:
Running the explosion on the sales order will generate a batch order to produce the 10 kg because we don't have any F1 on-hand:
Notice that the first line for B1 indicates that we get an additional co-product output of the type, By-product.
As both M1 and B1 are on hand, we can firm the planned batch order and start the production. (Planned orders -> Firm)
Processing the batch order
Let's report the batch order as finished with the expected input and output:
What happened to the cost?
I have set a material overhead of 10%, so looking at the cost perspective we get the following.
M1 20 kg = 20 * $10 = $200
B1 10 kg = 10 * $5 = $50
Overhead 10% = 10% * ($200+$50) = $25
Total = 200+50+25 = $275
B1 cost share (8kg): 8 * $5 = $40 (note this is fixed to the Std. Cost - no overhead)
F1 cost share (10kg): $275 - $40 = $235 (Incl. all $25 in overhead)
Second sales order
Let's create another sales order for 20 kg F1, to see how planning handles a shortage of the recycled by-product.
Running the explosion on the sales order will generate a planned batch order to produce the 20 kg. Notice the planned order for B1.
We still have plenty of M1:
- We have 80 kg and we need 40 kg for the additional order.
However, we are running short of B1:
- Initially, we had 15 kg. The first batch order consumed 10 kg and output was 8 kg, so now we have 13 kg.
- For the new order we need 20 kg, so a planned order for 7 kg is created to cover the missing ingredient.
With HF 2989470 that is included in Microsoft Dynamics AX 2012 R3 CU8, it is now possible to recycle and reuse by-product output from batch orders.
- The recycled product must use standard cost and have the production type, By-product or Co-product
- On the formula, co-product output must be of the type, By-product, and have the Burden type, Recycled
- Planning will now consider only on-hand inventory for by-products. So potential supply from batch orders is not used for pegging until the batch order output is posted.
