Defining an Active Concept 
Engineering processes only use the data of an active concept. It is read in the following processes:
·
During the
test phase, you can simulate the implementation of an active
concept.
In the simulation, the data of the active concept replaces the data of the
component variant. The product structure no longer contains data from the
concept group or the concepts.
· In the advanced concept phase, you can copy the data of the active concept to the component variant.

You can define one concept as the active concept.
When you create the first concept in a concept group, the first concept automatically becomes the active concept. Once you have added at least one more concept, you can define another concept as the active concept.
You have maintained the product structure in the iPPE Workbench. The product structure contains a component variant that has a concept group with at least two concepts. Choose the following path: Logistics ® Central Functions ® Engineering ® Product and Process Engineering ® Product Designer.
Start
the product designer in change mode. Load the product structure, and
display the Basic data 1 tab page for the component variant
.
...
1. Scroll down until you see the Concept Reference dataset.
2.
Check the
entry for the concept group.
On the Basic Data 1 tab page, only the active concept is
shown.
3.
If you check
the concepts and want to define a different concept as the active concept,
choose
(Detail View) for the concept
group.
The Concepts
tab
page appears.
In the Active column, you select the concept whose data transfer you want to simulate or execute.
4.
To save your
data, choose
.
You have defined the selected concept as the active concept. The product structure is automatically updated in the navigation area.
The concepts are shown with the following indicators:
Inactive
concept
Active
concept
The active concept is used in the following processes:
· Copying Concept Data to the Component Variant

We recommend that you do not delete an active concept. If you delete an active concept, you see a warning message. In this case, define another concept as the active concept.
