BP Account search in IUICMD Component with custom fields

Hi Experts,

Need help in the following scenario.

My task is to add custom fields for search in the SearcAccount View of the IUICMD Component

The search context node is of the type BuilHeaderSearch.

To implement the change I did the following

1. Modefied context node attribute structure with custom fields.

2. Created an implementation for the badi BADI_CRM_BUPA_IL_SEARCH_EXT

with filter value as BuilHeaderSearch and implemented its methods ex.

IF_EX_CRM_BUPA_IL_SEARCH_EXT~SEARCH_CRITERIA_INITIAL to set CV_IS_NOT_INITIAL when searched with custom  fields .

and IF_EX_CRM_BUPA_IL_SEARCH_EXT~SEARCH_PARTNERS to carry out the search.

But the implementation is not getting triggered on search.

My question is is it the correct BADI in this scenario or the only BADI for the component is

CRM_IUICMD_BADI?

Thanks in advance for any help.
