Set an effectivity group to configure occurrences

You set an effectivity group or groups to configure the product structure occurrences in addition to the revision rule.

Procedure

1. Load the assembly to configure and choose Tools→Revision Rule→Set Date/Unit/End Item.Teamcenter displays the Set Date/Unit/End Item dialog box.

2. Enter the effectivity group identifier in the Effectivity Group box, and then click Replace, Insert, or Append to update the list of groups.Note To remove an effectivity group from the list, select it and click Remove.

3. (Optional) To view the multi-unit configuration on an effectivity group, select it and click View/Edit. The system displays the View/Edit Multi Unit Configuration dialog box, as described previously. If you have the necessary access privileges, you can also modify the configuration.

Caution You can configure product structures with incremental changes using effectivity groups. However, only limited support is provided to configure occurrences with incremental changes using multi-unit configuration and the following limitations apply.

You can configure only the addition and deletion of occurrences using effectivity groups. Other edits in the context of incremental change cannot be configured.

An add occurrence edit is effective if the multi-unit configuration partially overlaps the effectivity of the incremental change.

A remove occurrence edit is effective if the multi-unit configuration completely overlaps or is within the limits of the effectivity of the incremental change. That is, a partial overlap is not sufficient to configure the remove edit. If there are multiple remove incremental changes, Teamcenter compares each of them with the multi-unit configuration separately. (It does not calculate the total remove effectivity and compare a single value with the multi-unit configuration.)

Teamcenter evaluates the configuration of an occurrence based on an incremental change independently of its occurrence effectivity.

If Teamcenter finds competing incremental changes (one adding the occurrence and the other removing it) and both can be configured with effectivity groups, it gives precedence to the add occurrence edit.

Results

When you apply the configuration, the system matches the occurrence effectivities configured for each occurrence with the multi-unit configuration set in the effectivity groups. Any occurrence whose occurrence effectivity is valid for any of the end item and unit range entries in the effectivity groups is displayed. An occurrence is loaded only once even if its effectivity matches more than one end item entry in the effectivity groups set in the session.

Examples

The following examples show how occurrence effectivity and incremental change interact.

Structure line number	Type	Occurrence effectivity (explicit or implied)	Effectivity on removing IC1 and removing IC2	Multi-unit configuration set on BOM window	Result
1	Component	EndItem(1-20)	IC1(-) → EndItem1(1-9) IC2(-) → EndItem(10-20)	EndItem1(1-9)	Occurrence not configured.
2	Component	EndItem(1-20)	IC1(-) → EndItem1(1-9) IC2(-) → EndItem(10-20)	EndItem1(1-20)	Occurrence configured as Teamcenter checks occurrence effectivity, multi-unit configuration, and each incremental change individually.
