Creating Combination Overrides
You do not have to create overrides for only a single variation. A material might be specific to a combination of variations, such as when a given source only provides certain colorways in a specific material, and provides different colorways in another material. In this case, a source-colorway override is necessary.
You create combination overrides in the same manner as you create single variation overrides. You must use variations rows to create combination overrides.
Click Variations and select any variation combination that you want to create overrides for.

You do not need to click Hide/Show to display the Variation columns. The system automatically displays the Variation columns for the variations that you have selected.
Certain variations combinations might not be enabled. Contact your administrator if you receive a warning message that your combination of variations is not valid.
You do not have to click Save after you create each combination override.
You can collapse and expand each component while selecting different combinations. The overrides you create are stored until you click Save. Then, your overrides are permanently saved.
You can exit the Edit BOM window at any time without clicking Save or Save and Check In. Any overrides you created or modified since your last save are discarded.
You can select a combination override by clicking the overrides existing icon . Clicking the name of a variations combination displays all selections for all variations, as well as all applicable variations columns.
Combination Overrides and Override Priority
Based on overrides created on individual variations and the order of priority, overrides might already be visible when you expand the rows to create combination overrides. Overrides roll up to the top-level component, so an override that is visible when you expand the rows does not necessarily indicate that an override exists for that variation combination.
When considering a combination override, such as source-colorway, the expanded rows display those materials, suppliers, and colors to be used. Changing a material, supplier, or color at the variation combination level creates an explicit override for that combination only. This allows you to create general overrides for the individual variations until a more specific override, such as source-colorway, takes precedence.
