F4 on LIFNR fails to capture the values in SELECT statement

Question

Hi all,
In the last 3 days Ive faced two issues on F4 Helps and its freaking me out.
The first issue I chose to ignore because of time-constraints and able to find a work-around.
On the second issue Ive hit a brick-wall.
Anyways here are my two issues.
Issue I:
I developed a custom report and in that Ive defined a selection-field(among half a dozen others) as follows:
select-options: s_matnr for ekpo-matnr.
On execution when I press F4 on matnr field I get the standard F4 Help. And then when i select the Material I want and hit Enter, the selected value fails to reflect in the Input Screen field. I continues to show blank as if Ive not selected anything. Not surprisingly the Report output was fetching the undesired results.
Later I changed the declared to:
select-options: s_matnr for mara-matnr.
And it worked. However because of time constraints I did not dwelve into it anymore.
This bring me to the Issue II:
For a different Custom Report Ive defined Select_Options on LIFNR as follows:
select-options: s_lifnr for lfa1-lifnr.
Now the issue I face here is slighly different.
On hitting F4 on the LIFNR field Im getting the standard F4 Help, and on selection Im getting the desired Vendor Number on the input screen.
But the problem is while executing the report its not fetching me the records relevant to the selected LIFNR. In debugging it does show me that LIFNR contains the value but surprisingly its not returning any values to the Internal Table.
Im out of ideas at this point of time, trying to figure out whats wrong.
Any ideas on what could be wrong??

PS: Im not using any function modules for the F4 help. Just the straight-forward Standard F4 functionality.

What you say makes sense, but firstly I dont have a MATNR in my table and from the looks of it, its not advisable to use any other common field either. A vendor-wise search is of primary importance in this table. So cant really exclude that.
if Rob's advise was helpful, than it looks like that the domain in the custom table for the field is not lifnr
Well the Domain has always been LIFNR regardless of which Data Element I used.
And the domain should probably be changed, but this might cause compatability issues.
Rob,
What kind of compatibility issues are you talking about? What I have right now is a custom table with some test data. So I guess its ok to change the Domain and Data Elements as I wish and Adjust the Table. Right?
@Amit: I will look at your inputs a little more carefully and get back to you. Right now Im a little tied-up with other issues.
Thanks everyone.

Update:
So... as I said earlier, when I used CONVERSION_EXIT_ALPHA_OUTPUT on LIFNR the selection on LIFNRs worked just fine. But unfortunately the rest of the select-options returned zero results(if I left the LIFNR select-option blank). I found the reason to be that because of the conversion routine the LIFNR values are taken as space. So i guess its looking into the database table for blank values of LIFNR, which is never the case and hence no values returned. Anyways, I found a work-around for this and for the moment its working fine...to some extent.
Only constraint being that I cannot enter a range of values for LIFNR.
Heres the code Im using right now. Thought it might be useful for future references or somebody wants to fine-tune it, is welcome to do so.
if s_lifnr-low = space.
select * from zpst001 into corresponding fields of table ist_zpst001
       where tno     IN s_tno
       and   ebelp   IN s_ebelp
       and   pspid   IN s_pspid
       and   werks  IN s_werks
       and   pick    IN s_pick
       and   pstatus IN s_status.
else.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
  EXPORTING
    INPUT         = s_lifnr-low
IMPORTING
   OUTPUT        = s_lifnr1-low
select * from zpst001 into corresponding fields of table ist_zpst001
       where tno     IN s_tno
       and   ebelp   IN s_ebelp
       and   pspid   IN s_pspid
       and   lifnr   eq s_lifnr1-low
       and   werks   IN s_werks
       and   pick    IN s_pick
       and   pstatus IN s_status.
endif.
