hi,

after creating API method it should have some methods, attributes, events........... thats all given in SW01 transaction for the created api method.

1) OBJECT TYPE --

2) INTERFACES -- user defined

3) KEY FIELDS --- primary key fields that are used in api methods

4) ATTRIBUTES -

---

parameters used in api methods

5) METHODS -

---

user defined methods for api method

6) EVENTS -

---

user defined events in methods

these api methods with the help of all these components it will affect the bapi. i.e the functionality of bapi for which its defined is achieved by this components.

if helpful reward some points.

hi,

interfaces, events are components of oops.

interfaces contains method prototypes.

i.e. the methods which are in interfaces are having only definitions. they should be overrided in derived classes.

events: used for custom actions

for ex: when u click on some thing then any thing should be happened means that is written in events in oops.

key fields: primary key fields using in that methods

these all components are parts of API method. generally every legacy system supports oops concept. bapis are generally triggered from legacy languages only. inorder perform that changes in sap system all these are useful [API methods].

if useful reward some points.
