in the last years I have asked several time for support regarding SVT production. I never received an answer. As the issues are still there I try now again (and then may be will start OSS dialog if i do not get answer).
This is our finding in using SVT scenario production:
The process seems to have problems with "by- and or co products". Example:
One main product is produced together with a by product.
Imagine this; 10 t of main product should be produced an 5 to of by product (to make it simple: both should have 100% component A or B)
Now the goods movements are done. At the end e.g. 9 t of main product is produced and 4 t of by product and the production order is closed (Status "TECO").
If i check now the data: the difference of 1 t of by product still shows up as "planned value" for the production order.
This is happening for at least two different regulations. So this seems to be an issue in the process which i can not explain.
Any idea why this is the finding and how to avoid it as now the tracking is showing to "high values" ? (the planned values should be not existing any more).
PS: we are using a "more or less" current SAP ERP release version; I could not find any OSS note related to our issue
Some one explained it,
Co-Product: Valuable material generated during a production run together with other valuable materials
By-Product: Product that is produced incidental to the production process of other products. You enter by-products in the material list of a primary product or process material with a negative value.
This is completely depends on the process how the are handling the numbers , EHS FMs will track only the numbers based on the Goods movement.
This is strange case and we cannot comment on this deeply without knowing the entire PP process,
I hope this will give some hints.
