When to use Phantom BOM?

smkolsoft

In production BOM Line table there are two options for the Type field...
1. Item
2. Production BOM

I want to know when should we use the type Production BOM option
instaed of Item?

Thanks

If we use "production bom" in BOM of an item, then inventory of the chaild item will not be affected,

whereas the inventory of the child item will be affected that is shown in item master if we use "item" in BOM.

For virtual inventory we use Phantom BOM ( "production bom" in BOM )

For actual inventory we use ordinary BOM ( "item" in BOM )

My suggestion to you is to stay as far away from phantom BOM as possible. The reason is because you cannot plan for the finished product of a phantom BOM when you run MRP.

It also makes routing link setups more unnecessarily complicated.

We only recommend using phamtom BOMs for formulas that you do not have an item number for that requires assembly using your raw materials. i.e. a special color mixture requested by a customer for a special order that you cannot resell to other customers.

Phantoms are a standard manufacturing structural design aide. If you are not aware of what a phantom is, do not use it.

In essence if a subassembly is an item you need it in stock to consume it, if it is not there a production order will be raised. If however you never stock it then you "could" set it as a phantom and then the assembly will be blown through and the components will be required on the top build.

here we hold in item table only raw materials (materials we buy from vendors) and final products (we sell to customers)

however in the process of manufacturing we have many semi-products that consist of raw materials and other semi-products. We define these as BOMs but they have no representation in the item table

then in a BOM description of a final product we have these semi-products as Type=::"Production BOM" and have raw materials as Type=::Item
