Re: Pass field value from Request to Response Mapping, without BPM in PI 7.11

you can try using Globals in a UDF, thought I am not sure this works in PI 7.1

setParameter

public String setParameter(String parameterName, String parameterValue, Container container) throws StreamTransformationException{
GlobalContainer glc = container.getGlobalContainer();
glc.setParameter(parameterName, parameterValue);
return(parameterValue);
}

getParameter

public String getParameter(String parameterName, Container container) throws StreamTransformationException{
GlobalContainer glc = container.getGlobalContainer();
String value = (String) glc.getParameter(parameterName);
return(value);
}

good luck
