Exploding BOMs

To explode BOMs

Open: Bill of Materials > Enquiries > Explosion.

Select Explode to Level to view the BOM items at a particular level.
- Enter the number of levels you want to explode to.
  
  Note: This can take longer to perform if you have many BOMs.
  
  Leave clear to display the top level.
Select Explode Quantity to see the component quantities multiplied down through sub-assembly levels of the BOM.
- Enter the quantity that you want to 'explode'.
  
  If you enter a quantity of 1, this will give a different result from leaving the check box clear (as that automatically explodes a quantity of 1). This is because when the check box is selected, the quantity is multiplied down through sub-assembly levels, and when it is left clear, it is not.
  
  No rounding is done on the quantity you enter here but rounding is done on serial numbered BOMs during the explosion process. For example, you might enter 1.5. BOMs would be exploded for a quantity of 1.5. However, serial numbered BOMs would be rounded to 2.
  
  Leave clear to see a quantity of one BOM exploded.
Select the BOMs to view items for.
- Select Single to view items for one BOM only.
  - Select the Stock Item or Name.
- Select All to view items for all BOMs.
  
  Note: This can take longer to perform if you have many BOMs.
  - If version control is in use, select the statuses that you want to explode.
- Select Multiple to view items for multiple BOMs.
  - Click Select to select multiple BOMs.
Click Display.

The selected BOMs are displayed in the list expanded to the default level or the level you have specified.

The quantities will include the scrap percentage if you have selected to calculate scrap in Explosion on the BOM Settings Scrap tab.

Note: If you are exploding a quantity of BOMs multiplied down through sub-assembly levels, the sub-assembly level will show the quantity plus the scrap percentage quantity, whilst the top components will only show the quantity.

    Note: You cannot select View Stock Item Balances for miscellaneous stock items, or phantom A BOM that is not used as a stock component or in raising works orders. A phantom BOM is created and structured to contain groups of components, like a standard BOM. It is used in printed reports on stock structures. It can be used to collapse the sub-assemblies to reduce work in progress (WIP) and lead-time. It operates as a standard sub-assembly. However, the product code for the finished item does not appear on a higher level works order. Within Manufacturing, the components and operations of phantoms (and nested phantoms) are added to the top-level works order. These components and operations are given a sequence number of zero. In some manufacturing systems, phantom BOMs are employed instead of effectivity dates, to use up old stock before introducing replacement parts. If so, the old item is created as a phantom with the new item, the child of the old. Old stock is used up before new stock is ordered. When a phantom has zero stock, it is deleted and the new item is made part of the original BOM. Phantom BOMs are also known as non-returnable assemblies and blow-throughs.s.
