You can do this using the "extends" keyword in your rule.
Rule "shopping cart total exceeds 4000, give 50% discount"
when
<condition>
then
<action>
end
Rule "if order between 6 to 9 pm give additional discount of 20 %" extends
"shopping cart total exceeds 4000, give 50% discount"
when
<condition>
then
<action>
end
You can also disable the first rule and just use "extends" to limit the amount
of duplicate conditions in your rules. Note extends basically copies the
conditions from the first rule to what is being extended, but I believe it will
do what you are trying to do.

when
<condition>
then
<action>
call Rule"if order is between 6 to 9 pm, give additional
discount of 20 %"
end
Rule "if order between 6 to 9 pm give additional discount of 20 %"
when
<condition>
then
<action>
end
..............
Also i have a query like, Can we make rule like this
Rule "shopping cart total exceeds 4000 give 50% discount"
when
<condition>
then
<action>
Rule "if order between 6 to 9 pm give additional discount
of 20 %"

then
<action>
end
end
Can we make rules like above?
