SAP RAP: Implementing Dynamic Action Control Using Instance Feature Control

[#1]

When developing Fiori applications using the SAP RESTful Application Programming Model (RAP), business actions often need to be enabled or disabled dynamically depending on the current state of a business object.

For example, an application may have actions such as:

• Approve
• Reject
• Reschedule
• Cancel
• Submit

However, these actions should not always be available to the user.

Implementing Feature Control

In the behavior definition, the action can be declared with instance feature control:

action ( features : instance ) Approve result [1] $self;
action ( features : instance ) Reject result [1] $self;

The advantage is that the action availability is determined based on the actual business object instance.
