Thank you, now I got the point.

Yes. You cannot. You can do it in an interface but you cannot do it in an expression rule

You mean i cant updated the value of local variable or rule input?

I'm getting this error while applying above logic.

Expression evaluation error at function a!localvariables: Local variables may only be defined within the "local" domain. The local variable 'ri!sample' uses an invalid domain.

You cannot do that. Values of RI cannot be changed. As a matter of fact, values of local variables also cannot be changed once defined.

I did. How to do the other way around.

local!var1 : "sample data",

ri!data : local!var1

Did you see the screenshot?

I did get that point. My only point is how to work with both local variables and rule inputs.

THERE ARE NO OUTPUT VARIABLES!!!!!

My input is a ID......in the expression rule first I will get the value and do some process with that value and then processed data will be my output.

In this case I thought of using local variables for processing (like in traditional programming languages) and once its done I will assign back to output variable.

What exactly yoou are trying to get from expression rule. What are your inputs?

I'm not facing any problems regarding getting inputs and setting output, My problems is in implementing logic using rule inputs and local variables.

Your understanding is absolutely right. And on that track, in a traditional programming lang, you use parameters only to bring in inputs. You use a dedicated return statement to push the output. Same is here. You just avoid return rather you just write that statement.

I thought that rule inputs are like parameters of the function and local variables are like function variables,.....I have to do some process with parameters and local variables.

Why you have to pass local variable to rule input? Just pass local variable as an output.

You cannot update the values of variables in an expression rule. Also, you should not be needing it.
Rule inputs are for bringing inputs from outside the rule. For returning a value, you can just write it in the expression rule, as the last statement and it should be returned.

I'm not using this in interface, I'm doing this in rule expression.

under saveinto Parameter use a!save(ri!{varName},local!{localVariablName}). For example a!save(ri!data,local!data).
