In ECC we have Search helps using FM COM_SE_F4_HELP_EXIT for search help exits .This The function module incorporates a generic integration of the Search Engine Service (SES) into the F4 search help concept.
After migration to S/4 Hana and migrating enterprise search from Trex to HANA by note 2054157 whats should be done for search helps which are using the FM COM_SE_F4_HELP_EXIT. It uses the OLD SES.
Do we need to use a NEW FM or how does the old search helps work
