Search help PREM is empty

Question

We just upgraded to SAP ECC 6.0 and we are no longer able to do mathcode lookups on employees names.  i.e., PA20 and then in the Personnel No field when we enter =n.smith we get the message "No input help available (search help PREM is empty).  PA20 was just one example and it happens on all of our screens. 
I can see PREM in se12 search helps and it calls the HRMC_PREM_EXIT_A function module which calls the HRMC_PREM_EXIT.  Does anyone have any ideas as to what the problem may be and what I can do to fix it?  thx in advance for any help you can provide.

The OSS Notes you provided were not my problem in the end.  I have resolved my own problem and here are some of the details.  I certainly appreciate your response though.
In Previous versions of SAP (pre 6.0), we modified PREM to add our own search helps in PREM - Z_PREMK02 and Z_PREMN02.  In going to 6.0 these additional Z search helps did not exist in PREM and consequently the PREM search help was not functioning Properly.  It came up with an error u201CNo input help available (search help PREM is empty).u201D
To Resolve this issue I created a new APPEND Search Help ZPREM by doing the following steps:
- Go into se12
- Put in PREM for the Search help and click on Display
- Click on Goto -> Append Search Help and at the prompt type in ZPREM as the Appended Search Help Name
- Definition Screen should autopopulate
- In the Search helps for ZPREM add the  two Z Searchps above + the PREMN one
- Do Parameter Assignments for the 2 Z* ones of PERNR
- Once you have done all of the above go into both the Z_PREMK02 and the Z_PREMN02 and change the Search help exit to HRMC_PREM_EXIT_A
