Facing the issues with MM TCodes in SAP Portal

Hi All,

Guys I am having the problem in publishing MM Transaction code ME51N(All the Tcodes getting same issue)

I am facing the difference in Look and feel of Tcodes , In R/3 the transaction code having the ICONS(SAVE , EXIT, BACK,CANCEL)

But When I was publish the Transaction code I am not at all getting those ICONS ,instead of that I am getting text Buttons

Why am not getting the Icons I am getting Text buttons instead ot that ,I am directly uploading Backend Common roles into Portal using Role Upload

Please share your ideas .....
