Can't get ok_code &F03 (green back) from copied standard_fullscreen status

Question

Hi SDN,
we are on WAS640. I have a Z-Program which uses FM 
REUSE_ALV_GRID_DISPLAY.
Depending on different cases the ALV shows different tables using different t_outtabs. As for the different ALV tables, I also need differnt GUI Status...
Hence I copied the Standard Status called STANDARD_FULLSCREEN to Z_STATUS1 to X...
Now I notice, that all the ALV Buttons like Filtering and Sorting, which are defined in the pf-status under "Application Toolbar" work fine. Here I also added new buttons.
Under "Function Keys" in pf-status there is the ok_code &DATA_SAVE (the disk-symbol) - this is also accessible, bu the next oks like green arrow &F03 or yellow arrow &F15 are not accessible.
I have to change the navigation, as there is sometimes a long history in the program running, and sometimes ittakes 5 or more clicks on the green, yellow or red exit arrow to get back to the initial view of the program.
When turning on Debug mode via /h during runtime, I can see, that I get the ok_code &DATA_SAVE, but nothing happens for the navigation arrows - no debugger comes up. Why is that?
For the access of the ok_codes I follow the ALV FM and set up a form like this:
FORM uc_benutzer USING r_ucomm TYPE sy-ucomm
              r_selfield TYPE slis_selfield.
* save stuff
  IF r_ucomm = '&DATA_SAVE'.  "works fine
  ELSEIF r_ucomm = '&F03' OR r_ucomm = '&F12' OR r_ucomm = '&F15'. "does not work
       LEAVE TO TRANSACTION 'ZPMIM'.
   ENDIF.
some help appreciated,
kind regards, matthias kasig

Ok, If you get in the PAI you can check what the value of the OK_CODE is? SYST-UCOMM.
Then you can check whether or not this is handled. Note that it is good practice to copy the value of the OK_CODE to a temporary variable.
It's custom to set the PF-status everytime in the PBO (initialization module) of the screen.
