Allowing only 'display' & no 'change' access within J2EE

Question

Hi Experts
We're on EP 6.0 -SP11 WAS 6.40. We've only installed the Java stack & we use the ABAP as the UME data source. All the id's in the ABAP system appear at the J2EE level, For our J2EE administartion for using tools like the Visual Administrator we use the J2EE Administrator id J2EE_ADM_EPP(id created in ABAP before we started the WAS installation), this id allows change as well as display access in the J2EE, for the standalone log viewer also we use this id to connect from our client PC's.
1. I want to know if there is a way by which we can connect to the J2EE using an id which is only allowed 'display' access & no 'change' access. This is to allow passing some J2EE administration functionality to some persons whom we don't to make any changes.
2. For using the stand-alone log viewer can we connect using any J2EE id, which is not given the 'administrator' role within J2EE engine.
Thanks & Rgds,
Abhishek

data: cursorfield(20).
if sy-tcode = 'MM02'.
  get cursor field cursorfield.
  if cursorfield = 'MARA-BISMT'.
    authority-check object 'ZMDOLDMAT' id 'BISMT' field input
                                       id 'ACTVT' field input.
    if sy-subrc = 0.
      exit.
    else.
      message e009(zmd) with
       'You dont have authorization to change' 'OLD MATERIAL NUMBER'.
    endif.
  endif.
else.
  exit.
endif.
I am using the above code.. its working fine for my purpose but when they dont want to change the value of BISMT then its blanking out the value on the screen..
Any idea why its happening ??
thank you,
