Maybe I haven't explain very clearly. I will list some example:
First , I have the requirement 1000KG for material 30~40g Chicken wings(material B). I know I have 3 batch broiler(material A) will be slaughtered. Batch A1 is 10000EA which average weight is 1.5KG, Batch A2 is 8000 EA which average weight is 2.0 KG, Batch A3 is 7000EA which average weight is 1.9 KG.But I don't know the quantity will be product by every batch. So I will create only one production order of material B which order quantity is 1000KG.After production finished, we know batch A1 product 300KG material B which batch is B1 and batch A2 product 550KG material B which batch is B2 and batch A3 product 150KG material B which batch is B3. These confirmation will be entered in one process order. When batch traceability for batch B2, the batch A1,A2,A3 will be displayed in together. But the result we want to is just to display the batch A2.
