Hi Swetha,
In your code of Get_v_Method .
is it a AET created field? if it is a AET field then in my knowledge it will have name like EXT.fieldname.
ls_map-context_attr = 'aTTRIBUTE NAME'(JUST COPY THE NAME IN CONTEXT NODE')
ls_map-f4_attr = 'Only attribute with out any prefix'(' ' ). eg( 'ZTZONE' )
Append ls_map to: lt_inmap.
clear ls_map.
ls_map-context-attr = 'aTTRIBUTE NAME'(JUST COPY THE NAME IN CONTEXT NODE')
ls_map-f4_attr = 'Only attribute with out any prefix'(' ' ). eg( 'ZTZONE' )
append ls_map to: lt_outmap.
and also keep a break point in the SET method after changing the code.
