Custom EHSM Incident display OIF application not called

Hi Experts,

I am working on SAP EHSM incident management enhancement.I am expert enough in BOPF FPM . As per my client requirement we are developing audit management custom requirement similar to near miss. I have successfully created the audit management application to create an incident similar to near miss by copying standard incident management configuration. Similar to that i have copied standard incident display OIF application by copying standard application configuration.

But when i assigned my custom audit management OIF custom application to a custom role and assigned edit incident service it is not calling my custom application, Instead of that it is calling standard incident dispaly OIF application. Could you please help if you faced similar issue .

Thanks in advance to all.
