Veera, please review the following Drools rule:

import java.util.Map;
import pl.net.bluesoft.rnd.processtool.model.ProcessInstance;
import pl.net.bluesoft.rnd.processtool.model.ProcessInstanceSimpleAttribute;

global Map result;

rule 'marketing items'
dialect 'mvel'
when
    $pi : ProcessInstance()
    $inAttr : ProcessInstanceSimpleAttribute(key=="category", value=="marketing_items")
then
    result.put("logEntry", "process.log.ext.axa.substantial.marketing_items");
    result.put("value", "GROUP");
    ProcessInstanceSimpleAttribute attr = new ProcessInstanceSimpleAttribute();
    attr.setKey("substantialAcceptanceGroup");
    attr.setBpmVariableName("substantialAcceptanceGroup");
    attr.setValue("MARKETING_ACCEPT_QUEUE");
    $pi.addAttribute(attr);
end

In this example, we have added an attribute named 'substantialAcceptanceGroup' to the process instance data. This attribute will also be available to the BPM engine expressions (e.g. decision nodes).

By updating the result java.util.Map, we have also managed to supply result variable coming directly out of Drools step in the process execution.
