In this SAP ABAP tutorial I will show you how to make hospot or single click area in Object Oriented ALV ( OO ALV ) using CL_SALV_TABLE.
To achieve this functionality you need to call the method set_cell_type of class cl_salv_column_table and pass the value as if_salv_c_cell_type=>hotspot . Now clicking on the checkbox will trigger the event LINK_CLICK , so we need to declare and event handler class here lcl_event_handler and declare a method m_link_click to handle the action . The LINK_CLICK event will give us the row and column value of the selected row , so that we can do further process based on the value of that field.NB : Hotspot coding is similar to the checkbox one of.my previous tutorials except instead of if_salv_c_cell_type=>checkbox_hotspot we need to pass if_salv_c_cell_type=>hotspot .
At the end we need to call the REFRESH( ) method of class CL_SALV_TABLE .
In this SAP ABAP tutorial example we are making the column vbeln values as hotspot so that when the user single click on the value it will lead us to the transaction ‘VL03N’ with the corresponding VBELN value.
