Hi Shilpa,
As you mentined in the thread, i think , you reqiured to create an implenetation for the badi by
1. SE18 2. Type Badi name(click display): CRM_ORDERADM_H_BADI
3. menu->implementation>create->(give name)
4.then Write the code for the Method :CRM_ORDERADM_H_MERGE
Can you explain for what purpose or requirement it is needed to enhance the BADI - CRM_ORDERADM_H_BADI ??
For your reference this is the Documentation of the BADI :CRM_ORDERADM_H_BADI
BAdI: General Processing of Header Data
In this step, you can create enhancements for processing header data in transactions. The following data is availabe to you in the Business Add-In CRM_ORDERADM_H_BADI:
CRM_ORDERADM_H_CHECK: BAdI to check object ORDERADM_H
CRM_ORDERADM_H_MERGE: BAdI to merge object ORDERADM_H
CRM_ORDERADM_H_CHECK
Additional checks can be carried out - the results of these checks can be copied as error messages.
All parameters are copied as importing parameters in the interface.
The error message error_occured can be triggered.
CRM_ORDERADM_H_MERGE
All parameters are copied as importing parameters in the interface.
An individual BAdI structure containing the communication fields for the object is copied as a changing parameter.
If the error message error_occured is triggered, an error message is copied to the application log. If no error is triggered, the changed data is copied from the BAdI structure to the wrk structure. This means that you have the option of changing values for this object with this BAdI.
Prerequisites:
In order that you can use a business add-in, an implementation must be generated for the availabile definition for the BAdI, and the relevant methods must be programmed.
Recommendation:
Error messages:
Error messages should not be issued directly, but should be forwarded to the application log using the function module CRM_MESSAGE_COLLECT. By defining the error gravity, you can define whether it leads to a program termination, an incorrect status or only a warning in the transaction.
The error messages issued must, however, be deleted by the implementer at the start of the BAdI, as otherwise they will not disappear from the log file, and the system would therefore continue to display the error, even if it was already solved.
Example
data:
    ls_msgidno type bal_s_idno,
    lt_msgidno type  bal_r_idno,
    lv_save_message    type c.
ls_msgidno-sign       = 'I'.
ls_msgidno-option     = 'EQ'.
ls_msgidno-low-msgid  = 'CRM_ACTIVITY_H'.
ls_msgidno-low-msgno  = '801'.
append ls_msgidno to lt_msgidno.
call function 'CRM_MESSAGES_DELETE'
  exporting
    it_r_msgidno   = lt_msgidno
    iv_ref_object  = is_activity_h_wrk-guid
    iv_caller_name = gc_object_name-activity_h. " See include programCRM_OBJECT_NAMES_CON
*In the error case, collect the message:
if <error_condition>.
  messge id 'CRM_ACTIVITY_H' type 'E' number '801'
         into lv_save_message.
call function 'CRM_MESSAGE_COLLECT'
  exporting
    iv_caller_name = gc_object_name-activity_h " See include programCRM_OBJECT_NAMES_CON
    iv_ref_object  = is_activity_h_wrk-guid.
endif.
Screen with customer fields
If you want to depict customer-specific fields on a screen, follow the corresponding procedure.
Activities
1. Create an implementation.
2. Assign the BAdI definition to the implementation.
3. Navigate to one or several methods in the editor, using double-click, in order to program the methods.
4. Activate the methods.
5. Activate the implementation.
