Message-Mapping: Use same RFC lookup for different target fields

Question

Hello,
I need to apply an RFC Lookup which delivers a boolean flag back (true or false). This RFC lookup should be used for different target fields.
Is there a way to execute the RFC lookup just once and then store the result in an internediate variable that I can use for all futher checks for different target fields?
If this is not possible and I have to apply the RFC lookup for all necessary target fields is it then executed for each target field ? This is exactly what I want to avoid in order not to slow down performance.
The input parameter (=source field value) would be the same.
Thank you for your advice!

Exactly.
Here is a UDF example I have that you could adapt to your needs.
Set
public String setCounter(String a,String b,Container container){
/* Store values in global datacontainer
a: mapping value and return valueparameter
b: name for stored value parameter
GlobalContainer myGlobalContainer;
myGlobalContainer = container.getGlobalContainer();
myGlobalContainer.setParameter(b.toUpperCase(), a);
return a;
Get
public String getCounter(String a,Container container){
   //write your code here
GlobalContainer gc = container.getGlobalContainer();
if (gc.getParameter(a) != null) {
  return String.valueOf(gc.getParameter(a));
} else {
return "1";
