Use below steps to disable icons in ABAP ALV toolbar.

1. Add a column to the internal table to hold the traffic lights value(i.e. 1 for RED, 2 for YELLOW and 3 for GREEN).
2. Fetch data from database table and build field catalog.
3. Assign different traffic lights to each row based on condition.
4. To display traffic lights in the ALV, fill the lights field name in the LIGHTS_FIELDNAME of ALV layout.
