Project Models

A project model is an organization-specific model in an organization that can be constructed by basing it on a reference model. However, certain model items that can be used in a project model are not included in a reference model.

These model items must be imported directly from the repository. You can also ignore existing reference models and create a new project model. The Enterprise Modeler concept advises you to import a reference model into a project model and make the necessary modifications to have the project model fit the organization-specific requirements.

Several project models are possible.

A project model is built from a library repository of the following model items:

Business control model
Business function model
Business process model

You can link model specific Help to all the model items in a project model. Model specific Help should provide information about the function of a model item in a business model.

Any references in this text to the company-specific character of project models must be seen in a broader perspective. Actually, project models do not only relate to a specific organization, but to any specific organizational unit. This chapter describes project models by identifying and explaining the mandatory and optional sessions to create a complete project model in which all the model items are properly connected.

The project model procedure

Project Models (tgbrg4500m000)

The Project Models (tgbrg4500m000) session is the main session for building project models; from this session you can access every model item and corresponding functionality needed to build a consistent project model.

To do this:

From the Zusatzoptionen menu of the different project model related sessions, click the icons or select the appropriate options.

To create a project model:

Click the New
In the Project Model field, specify a name for the project model.
In the Owner field, select the LN user who created the project model or is responsible for its maintenance.
Click Save

Field	Description
Key fields for the Project Models (tgbrg4100s000) session
Copied-From Type	This field shows if the project model is copied from a reference model or another project model. Therefore, it can have the value reference model or project model.
Copied-From Model	This field is automatically filled with the name of the project model or reference model from which the current project model is copied. Copying can be done using the Copy Reference Model into Project Model (tgbrg4205s000) session.
Copied-From Model Version	The version of the reference model or project model from which the current project model is copied.
Expired	In this field you can indicate if the project model is still valid.

Icon	Description	Activated session

Import reference model

To import a reference model into the selected project model:

On the Zusatzoptionen menu of the Project Models (tgbrg4500m000) session, click Import Reference Model ...

The reference model you import must reflect the situation in the organization typology of the organization for which the project model is created; this way, you only need to enter the organization-specific details that differ from the default that applies to the organization typology.

To select the reference model you want to import into the Project Models (tgbrg4500m000) session, click Import Reference Model ...; this starts the Reference Models (tgbrg3500m000) session. During the import, a snapshot of the reference model is made, after which the snapshot is placed in the project model.

This means the following:

The model items you can see in the project model are references to the physical model items in the repository.
Any changes made in the reference model after the import does not affect the project model, or vice versa.
