Hello @SanjivaniLahane 

SInce caller field is mandatory, 

you need to have value and then make mandatory false after that make read only.

Please use below steps

g_form.setValue("caller_id", g_user.userID);
g_form.setMandatory("caller_id", false);
g_form.setReadOnly("caller_id", true);

Please mark if I have answered you
