user id not getting updated
I have created Web dynpro application which is working fine within which i have created one node lets say 'PERNR' in view
'VIEW' for input from user being displayed. Now that application we are connecting it to portal to which user can login and access that application. The input field PERNR is in read only mode. The requirement is that when user login throgh portal that id should get placed in PERNR.? How it can be done in Webdynpro ABAP?
