Enhance the view "InboxSearch" in the cpmpoent "ICCMP_INBOX/InboxSearch"

Question

Dear Expert,
I need to enhance the view "InboxSearch" in the cpmpoent "ICCMP_INBOX/InboxSearch" with new field for example: Affected employee (Partner number and Partner Function both as F4 Search.
Could you give a step by step description, how to do this?
As far I know I should:
1. Extend the Structure: CRMST_AUINBOX_SEARCH with needed field
2. Add field to the UI
But I am not sure how to move foreward. Some threads are mentioning the Badi: CRM_IC_INBOX_BADI.
Thank you very much in advance for your help.
Best regards
Ahmed Hadi

Ahmed,
Apologies for delay replying, SDN was unavailable when I tried to reply yesterday.
Our team does not shy away from developing SAP CRM to meet our requirements, but the Agent Inbox is very complicated and very difficult to enhance, so it's not something we've done many changes with.
If the request is a 'nice to have' then I would advise the business that the change would require a large amount of development and testing (it is very easy to reduce Inbox search performance and/or not return the correct results). 
Most changes to the Inbox can be accomplished through the BADI you've mentioned and using either the BEFORE_SEARCH or AFTER_SEARCH methods.  However, with your requirements I suspect you will need to enhance the context of the Inbox to bring in the two new fields (created using the Easy Enhancement Workbench).  You'll need to take a Z copy of CL_ICCMP_IN_INBOXSEARCH_CN00 in order to include getters and setters for your new fields along with any lookup help attributes.
I'm sure there are many ways to skin your cat, but I'm sure you'll need to use the Inbox BADI.  I'm not a developer though, so I may be totally wrong in what I've said here.
Hope this helps, all the best and good luck with your project,
Andrew Griffin.
