Problem in Expand when using Blocked ALV list
I am using the Blocked list ALV to display two lists in a program. One among them is a hierarchial ALV. When i click on the Expand button of this ALV it terminates with the runtime error "GETWA_NOT_ASSIGNED".
I was able to use this functionality using similar code in a stand alone hierarchial ALV list in another program without any problem.
I have assigned the Expand Field name as follows in both programs:
wa_layout-expand_fieldname = 'EXPAND'
Any suggestions or help in this would be highly appreciated.
Thanks & Reagrds,
