Raw Material Vs Consumable

Please tell the difference between Raw Material And consumable in item group
if possible elaborate with an example

Consumables are items that are not a part of the BOM (like Oil, maybe hardware etc)

Best to get help from an accountant for what applies to your case.

Could anyone just tell me how to work with consumables as it is not a part of BOM ,the consumable quantity never changes , but I issue consumables to few warehouses . How do I enter the consumption ?

Raw materials will be converted into another product. Consumables are used in the production process but only just to keep the production process moving. They are not converted into another product. Examples of consumables are engine oil for a machine, ink for a printer, thread for a sewing machine etc.

It is for this reason that consumables should not form part of your BOM
