Extensions in OAF ?

We will see the different types of extensions in OAF (Oracle Apps Framework).

We use extensions if we want to do any changes in the already shipped oracle E-Business suite.

The main purpose we use extensions is to make changes in the already well designed Oracle E-Business suite pages. 

We have two types of extensions

1. BC4J Extension
2. Controller Extension

BC4J Extensions are again divided into three types and they are:

• VO Extension
• AM Extension
• EO Extension

So total we have 4 types of extensions .

1. CO Extension
2. VO Extension
3. EO Extension
4. AM Extension
