Configure structure using group effectivity

You can configure product structures using group effectivity, which combines multiple end items, unit ranges, or date ranges to simultaneously manage the effectivity of various occurrences. You can also add, modify, or remove these group effectivities.

A group effectivity is a combination of multiple end items and range of units for each end item or multiple date ranges. When you want to configure multiple occurrences at the same time which have different effectivities on them, you can configure using group effectivity. You can configure the structure by adding group effectivities if your administrator has configured it for you at your site. Group effectivity is used to configure product structure occurrences of an assembly by:

Specifying multiple end items

Specifying the unit effectivity ranges for each of those end items

Specifying multiple date ranges

Configure a structure using a group of unit effectivities and end items

Procedure Search and open the structure that you want to configure with group effectivity.

Select the structure and click Units

Groups.

In the Group Effectivity pane, click the Add Group Effectivity icon.

Click New.

Specify the effectivity Name.

Specify the desired unit or a range of units in the Unit field.

In the End Item field, click Add to add a new End Item or search for an existing End Item.

Once the unit and end item information is entered, a new row is added to the table.

Add more units and unique end items as required.

Click Add.

A group effectivity is created and applied to the currently displayed structure. As the effectivity criteria set in the header, and in the revision rule are in sync, you may lose any earlier configuration done using the revision rule.

Configure a structure using a range of date effectivities containing an end item

Procedure Search for and open the structure that you want to configure with date range effectivity.

Select the structure and click Date > Date Range.

In the Date Range Effectivity panel, click New.

In the Name box, specify a name for the date range effectivity.

In the Start box, specify a start date for the date range effectivity.

In the End box, choose one of the following values:

Date

UP - All Future Dates

SO - Stock Out

In the End Item field, click Add .

Select an end item from the Palette tab or search for and select an end item from the Search tab.

Click Add.

Click Apply.

Edit or remove group effectivity of units and end items

Procedure Select the structure which is configured with group effectivity and click Units > Groups.

In the Group Effectivity pane, select the effectivity that you want to edit or remove.

The Remove Group Effectivity and Edit icons are displayed.

To remove the group effectivity, click the Remove Group Effectivity icon to remove the effectivity.

To modify the group effectivity, click Edit and then change the properties you want to edit.

Click Save.

Edit or remove range of dates

Procedure Select the structure which is configured with group effectivity and click Date > Date Range.

In the Date Range Effectivity pane, select the date range from the Search tab.

To edit the date range, click Edit and modify the dates and click Apply.

To remove the applied date range, select Today from the header.
