Hello Pradip,

Pls go through the following....

Creation instances for existing BADIs

**********************************************

Se18 is the definition of a BADI.You can create se19 to create an instance of the definition and use it.

eg: 1) go to SE18 and get any badi name

2) go to SE19..create a new implementation..it will ask for a definition name

give the name of the BADI from definition

3) you can see that you have created an instance of the standard BADI

So you are defining a BADI in SE18 and creating it's implementation in SE19

if a message that the BADI cannot have multiple instances then it means already an implementation exists and we cannot create any more and sometimes during creation a message that the BADI is for SAP internal use also indicates that the instances for theses cannot be created

WHY u need a BADI? + Example

******************************************************

This is a link discussing the need of BADI,with example..if not found sufficient you can check the following

WHY u need a BADI?

**********************************************

Different BADIs serve different purpose..some can be used for checking,modifying,

bringing a screen etc...

To see different BADIs ...go to SPRO ->SAP Reference IMG Tab ->

go to the respective MODULE eg : SALES and Disrtibution (SD)

SD->System Modifications->Bussiness ADD-IN

EXAMPLE!!!

**********************************************

We will see a BADI for Transaction MIGO

ok,please do the following steps for a hands-on example

1)Go to SE19..CREATE a badi ZTEST_BADI

give the definition name as MB_MIGO_BADI

the purpose of the BADI is to add an extra tab in the HEADER and ITEM for

standard transaction MIGO

2) Fill the text details

then on the top menu -> GOTO ->Sample Code-> COPY

A message will come saying overwrite will happen...say OK and activate the

BADI..Once you run the transaction MIGO you can see an extra tab

MIGO_BADI_EXAPLE in header

3) To study more inside SE19,for the newly created BADI click on the interfaces

and you can see that for every purpose a method is defined and its description

is also there.You can add new fields in the TAB...save a back up to a custom

table etc based on the parameters being passed into the method,which is just

like a function module...if you pass parameters you can do the actions allowed

for those inside that method but in BADI you cannot add any new parameters to

be passed..whatever is provided you can use

4)You can debugg and understand the flow,but please bear in mind that this is

OOPS concept

Hope the above mentioned serves your purpose

Reward points if useful
