ServiceNow Get Variable Name in Business Rule (Record Producer or Service Request)

current.variables.<variable_name> 

for a record producer where you don't know the variable names this type of approach could work:

/*var producerVars_allVars = new GlideRecord('question_answer');

producerVars_allVars.addQuery('table_sys_id', current.sys_id);

producerVars_allVars.addQuery('question.type', '!=', 11);

producerVars_allVars.addQuery('question.type', '!=', 19);

producerVars_allVars.addQuery('question.type', '!=', 20);

producerVars_allVars.query();

while (producerVars_allVars.next()) {

var varName = producerVars_allVars.question.name.toString();

if (!gs.nil(varName)) {

if (varName == 'business_role_iga') {

sDescr += '\n';

sDescr += 'varName';

sDescr += ': '

sDescr += producerVars_allVars.value;

}

}

//allVars.push(producerVars.question.name.toString());

}*/
