Hi,
You should not modify standard SAP search helps - they are generally easy to replace with customer search help versions without modifying the original.
Sample Process is here
In SE11 display the original BUPA collective search help, and select the menu option "Goto-->Append Search Help". This will display a pop-up listing existing appends. Select the create button in the pop-up and give the new append a Z name - say Z_BUPA and save it. In the new Z_BUPA append go to the Included Search Helps tab and type in BUPAA and select the "Hide" checkbox. Save and activate. This has now hidden the BUPAA help in the original BUPA collective search help - go back and test it to see.
To add a replacement, copy BUPAA to a ZBUPAA search help and add it as an included search help in your Z_BUPA append. for this one you will need to select the Param Assignment button to link parameters between the collective and elementary search helps.
Doing the change this way means future support packs will not overwrite the changes you have made.
If the view or function needs changing, these should be copied to Z versions and changes made. The original code in the function module could instead be repaired using Modification assistant if there are not too many complicated changes.
With the BUP_SHLP_EXIT_SEVERALS function, there are a number of references to the search help name in the function that would need to change to the new Z name. Other changes depend on your requirements - The function is called a number of times during the search help display, with a different step executed each time (PRESEL1, PRESEL, SELECT in this case) - mods may be needed to only some steps. The steps are partly documented by comments in the code.
The function BUP_SHLP_EXIT_SEVERALS appears to have a BADI exit included in the PRESEL step (exit interface IF_EX_BUPA_AUGRP) - this may be of some use.

Satish
