Hi Hiranya,
you have added the model but bol entities are not at reflected because that is giving error..
save that runtime repository and close the window again reload the zcomponent.
one more thing to to genil_model_browser or genil_bol_browser to check that model having bol entities or not..
just have go through this link too.
