Credit for Material

Hi,

Now i am at client place and i need to solve this issue very urgent. The requirement is like this:

The company want to deduct the scrap from costing sheet.

For example: Raw material weight: 5 kg Finished material weight: 3 Kg.So the difference 2 kg would be scrap. They are selling this scrap for 10 kg.

And this credit should be negative value.
