check related derivation

Overview

With Next Design, you can ensure traceability while editing the model by checking and editing the derived relationships between models when editing the model in the editor.

Below, we will explain how to check and edit derivation relationships in the following order.

• Check derivation relationships between models
• Edit derived relationships between models
• Check if there is a derivation relationship
• Check derivation related details

Check derivation relationships between models

To check derived relationships between models:

Operation procedure

1. Display two models side-by-side according to Two-screen display of model above.
2. Make sure the following check items are checked in the ribbon:
   • View > Editor > Trace Lines checkbox on the ribbon
   • View > Editor > Indicator checkbox on the ribbon
3. Selecting a model on the editor will highlight the trace line connected to that model in orange.

See

• See Check if there is a derivation relationship below for indicators and how to use them.

tip

• Derivation related can be checked and edited not only in diagrams but also in forms.

caution

• If the model of the derivation relation destination is outside the screen display range, the trace line will not be displayed even if the indicator shows that there is a derivation relation.
• In that case, please scroll so that the model of the derivation related destination is displayed on the screen.

Edit derivation relationships between models

To add or remove derived relationships between models, follow these steps:

Operation procedure

1. Point to a model in either editor and drag the [+] icon that appears in the upper right corner of that model.
2. While dragging, the [○] icon is displayed at the upper left of each model on the other editor. Drop it on the [○] icon of the model you want to connect the trace line.
   
3. Trace lines appear between the models when the derived associations are connected.
4. To delete the derived association, select the trace line and press delete.

caution

• Derived relationships cannot be added unless the profile defines any derived relationships that can be added between entities. The [+] icon on the upper right of the model is also not displayed.
• In some cases, the [+] icon does not appear in the upper right even when pointing to the model. In that case, click inside the editor area and then point to the model.

Check if there is a derivation relationship

When you view the models in the editor, small rectangles appear to the left and right of each model to indicate whether it has a derivation relationship. This display is called an Indicator.

info

• Indicators are visible even when only one editor is visible.
• When viewing models in form view, they appear as vertical rectangles on the left and right edges of each model.

The left and right indicators and their meanings are as follows.

Display Location	Meaning
Left	Derivation related sources
Right	Destinations related to derivation

Display color	Meaning
Blue	Records related to derivation
Outlined	No derivation related records

note

• If indicators are not visible for each model, make sure the [View] > [Editor] > [Indicator] checkbox on the ribbon is checked.

Check derivation related details

To check the model name of the derivation destination from the indicator or jump to the model of the derivation destination, follow the steps below.

Operation procedure

1. Click on the indicator to pop up the derivation related details.
2. If a derivation relationship is recorded, the applicable model is listed under [Source element] or [Derived element].
3. To jump to a derived related model, point to the listed related element and from the icon that appears to the right of the related element, click one of the following:
   • Show Design Elements in Left Editor
   • Show Design Elements in Right Editor
4. Press esc to close the popup display after the associated element is displayed in the editor.
5. The parent model of the related element displayed in the editor can be traced from the path bar displayed at the top of the editor.
