Answer / ambareesh.j28

Everything what you asked for lies in the field catalog. Let us assume there are totally 7 fields (A to G) , and 3 conditions (X,Y,Z). So your code should be something like this:

If X, Pass A,C,D fields to field catalog.
elseif Y, Pass B,C,G fields to field catalog.
elseif Z, Pass E,F,G fields to field catalog.
endif. 

Use the function modules REUSE_ALV_LIST_DISPLAY / REUSE_ALV_GRID_DISPLAY to execute the output and view it.
