Master iViews 

Definition

A master iView is coding written in Java as a portal component that is uploaded to the PCD as a .PAR file. The portal component developer must actively trigger the upload. The corresponding master iView is automatically generated when the .PAR file is in the PCD. The master iView knows which coding should be started when an iView is called in the portal. For example, an External Service refers to a master iView that knows that a transaction now has to be started in the portal.

Use

You use master iViews as a kind of template for creating External Services and Java iViews. A user can only see an External Service or Java iView in the portal if there is a link between the External Service (or Java iView) and the master iView. Once a master iView is in the PCD, you can access it with the following administration tools:

Based on a master iView you now have to decide:

  1. If you want to create an iView that does not need much space in the Browser window and therefore should be embedded on a page together with other iViews. In this case you should create a Java iView. You can do this in the iView Editor, which can be called within the administration role with the iViews entry.
  2. If you want to create an iView that needs a lot of space in the Browser window and therefore takes up an entire page. In this case you should create an External Service. You can do this in the Role Editor, which can be called within the administrator role with the Roles entry. For example you can create an External Service for an R/3 transaction. The External Service can then be added to a role.

If you create an External Service or Java iView based on a master iView, the master iView passes its properties to the object that is based on it. Also read Creating External Services Based on a Master iView.

Each master iView also has other properties, depending on why it was developed. For example, master iView Standard.URL.Component has the property ContentLink. This property is used for storing a Web address. If you now create an External Service from the master iView, you can create an iView in which a certain Web address is called.

Procedure

Master iViews can be changed in the Role Editor. This means that you can overwrite the default values of the properties of a master iView. When a new version of a master iView is loaded into the Enterprise Portal, the properties of the master iView that you already changed are not overwritten. Read also Configuring Master iViews.

You can also add master iViews directly to a role.
