in alv tree pgm when we use
LIST_VIEWER type ref to CL_GUI_ALV_GRID
the node_key of MTREESNODE can take upto 12 char only.
Now i have a requirement werein i need to pass few table names which are more than 12 char.I have created a z.... structure f same MTREESNODE with the node_key of 16 char.Now when i debugg the pgm i can see that since CL_GUI_ALV_GRID is a global class it still accepts the same 12 char format.
can any one suggest how could i pass value more than 12 char for node_key of MTREESNODE.
