Hi Chandra,

3. Importance of Delta link? & 4. What is a data Link? & 5. Difference between Copy and Delta Link?

Delta Link refers to a process of copying of portal object.

Parent-> Child, where the changes of Parent are reflected in Child after copy.

Copy refers to a process of copying of portal object.

Parent: Child,where the changes of Parent are not reflected in Child after copy.

6. What is the difference between Portal Component and Portal Service?

Portal component is a Portal Object that is developed for a specific requirements.

Portal service is a Portal Object that is developed for a generic requirement and this service can be used different Portal components by sharing the reference.

Hi, I can only answer your first 2 questions.

1. How two webDynpro Projects Communicate with each other?

First of all a prerequisite is that 2 components are able to use one another, this is done through the DC metadata. (Public part exposes a component to the outside world, in the DC definition you define the used components)

Then, when components can use one another, there are several ways through which components can communicate:

Eventing,

Context binding, and

Component interface calls (including navigation to other components via view interfaces).

I believe portal eventing is also possible, in this scenario components from different projects can communicate without being used by one another.

2. Importance of Logical Dictionary when we are creating Adaptive RFC model?

During import of an RFC, all required dictionaries are created automatically. There is no need to define additional data structures, unless possibly when you create custom code.

Good luck, Roelof
