Date/Unit Effectivity
Open the Date Effectivity tabbed region and enter the effective date range for each component.
The Date Effectivity tab is disabled if the BOM item's effectivity control is set to Model/Unit Number.
Open the Unit Effectivity tabbed region and enter the effective unit number range for each component. The unit number list of values displays all of the unit numbers defined in the master organization.
Effective date fields appear throughout Oracle Manufacturing products. These are defined as follows:
- Effective From / Effectivity Date: First date and time the component or operation becomes effective. For components, the effective date is the first day a component becomes effective for a bill. For routings, it is the first day an operation becomes effective in a routing.
- Effective To / Disable Date: Last date and time the component or operation is effective. After this date, you can no longer assign the operation to a routing. From this date, you can no longer assign the component to a bill.
- Inactive On: The first date and time the component or operation is inactive. As of 12:00AM on this date, you can no longer assign the component to a bill or the operation to a routing. If this date equals the effective date, the component or operation is inactive.
To avoid confusion, make sure that effective dates for one revision do not overlap with those of another.
For example, if you must introduce three new components to a bill in a specific order, you should assign each change to the appropriate parent item revision. So, component 1 of revision B may be effective today, component 2 of revision C tomorrow, then component 3 of revision D may be effective the following day. If there are two operations on a routing and you replace the first operation with a new operation, you should set the effective date for the new operation to the date the operation you are replacing becomes inactive.

If there are two operations on a routing and you replace the first operation with a new operation, you should set the effective date for the new operation to the date the operation you are replacing becomes inactive.
Effective dates can be either the current date or a date in the future; you cannot enter a date in the past.
