We can take yield and scrap into account when calculating the material requirement.
Let's study how to calculate the requirement when taking yield and scrap into account.
We can specify the [Yield rate] and the [Scrap quantity] for the "Input instruction" and "Output instruction".
At the [Order table], order "1" requires to produce 9 items of "AX".
Order "1" has been assigned already.
By looking at the [Inventory graph] it is easy to see that 9 items of "A" are required.
Please set 0.9 as the [Yield rate] for the "output instruction" and press the [Reschedule] button.
As 9 items of "AX" will be supplied to the next process, 10 items of "AX" will be produced and 10 items of "A" will be used.
This is because the [Yield rate] is set as 0.9.
Then, please set 1 as the [Scrap quantity].
Please, press the [reschedule] button and confirm that the required quantity of "A" increased by 1 to 11.
This time, please set 1 as the [Scrap quantity] for the "Input instruction" and press the [Reschedule] button again.
The manufacturing quantity of "AX" remains 11 items but the required quantity of "A" was increased to 12 items.
If we set 0.8 as the [Yield rate] for the "Input instruction" and reschedule it, the required quantity of "A" will change to 15.
For calculating material requirement it is also possible to use expressions.
