Defining a View for BOM Explosion
You can use the following indicators to influence the BOM explosion:
Alternative priority
When you explode a BOM, this indicator determines that the system only searches for the alternative you enter in the Alternative field in multiple BOMs.
Material
The following table illustrates two different explosions of this multiple BOM, produced according to different selection criteria.
Explosion with Alternative Priority
Your selection criteria in these fields |
Produces an explosion as follows: |
Alternative: 03Alternative priority: X |
Explosion continuously to level 2 |
Alternative: 02Alternative priority: X |
Only to level 1 |
Scrap
This indicator affects how the component quantity is calculated as regards scrap values. If you want to take scrap into account, the system increases the required quantity by the scrap factor defined. If this puts the required quantity in a different lot size, the system determines a different alternative, provided that the material master supports selection according to order quantity (View MRP 2, Alternative selection field, value Blank).
The following scrap values are relevant:
If assembly scrap is maintained for an assembly in its material master, the system applies this scrap factor to all components of the assembly (with the exception of components that have operation scrap). Component scrap only affects an individual component.
Material A has an assembly scrap factor of 10 % and a multiple BOM with the following alternatives:
Alternatives with Lot Size
Alternative |
From lot size |
To lot size |
01 |
1 |
1000 |
02 |
1001 |
2000 |
The required quantity entered for the BOM explosion is 1000.
If you do not take scrap into account, the system explodes alternative 01. If you set the scrap indicator, the required quantity is increased by the scrap amount (1000 + 100), and the system explodes alternative 02.
Sort
For a summarized BOM, you can enter a sort procedure in this field for the BOM components. You can sort the components according to the following criteria:
The following overview shows the components of BOM A.
Components of BOM A

If you do not take the sort string into account (Sort string field with value Blank or 1), items 0010 and 0020 are displayed as one item with a sum quantity of 22.
If you do take the sort string into account (Sort string field with value 2), items 0010 and 0020 are displayed separately. The system sorts the items in ascending order according to the sort string (0030, 0040, 0010, 0050, 0020).
