EDIFACT messages require a total segment count in the segment UNT. X12 messages require the same information in segment SE data element 96.

In SAP Process Integration/Orchestration(PI/PO) this requirement was handled by mapping the constant $B2B_SEG_COUNTER to the relevant field. SAP Cloud Integration doesn't have this feature yet, but we can create a Groovy script that replicates exactly the same behavior.

You can put this script just before the "XML to EDI converter" step, or after "EDIFACT Post-processing" step. It is flexible and it can be used when the message body has the XML root element starting with M_, or the root element is Interchange.

You can map $B2B_SEG_COUNTER to any field. You can use the constant function in Integration Advisor.



Note that groovy.util.Node returns String in Groovy IDE and a QName object in Cloud Integration. This behavior is flexible in the Groovy spec. "getLocalName" function handles this difference.
import java.util.HashMap;

def Message processData(Message message) {

String magicKeyword = '$B2B_SEG_COUNTER'

def body = message.getBody(
def parser = new XmlParser()
def ediXmlDoc = parser.parse(body)

Integer segmentCount = 0

//find message and count segments inside
ediXmlDoc.breadthFirst().findAll { possibleMessageNode ->
// GroovyIDE returns String, Cloud Integration returns QName here.
// println
// The implementation is flexible in the Class spec. .name() function returns java.lang.Object.
// It is possible that since this input has no namespace, it returns string.

// it is a message node
if ( getLocalName(possibleMessageNode).startsWith("M_") ){
possibleMessageNode.breadthFirst().findAll { possibleSegmentNode ->
// it is a segment node
if ( getLocalName(possibleSegmentNode).startsWith("S_") ){
// println
segmentCount ++

// find nodes to be filled
ediXmlDoc.breadthFirst().findAll { node ->
if (node.localText().size() > 0 && node.localText().first() == magicKeyword ){
node.value = segmentCount

// Write document to body
def sw = new StringWriter()
def xmlNodePrinter = new XmlNodePrinter(new PrintWriter(sw))
xmlNodePrinter.with {
preserveWhitespace = true

String result = sw.toString()

return message;

def String getLocalName( groovy.util.Node node ){
def name = // can be java.lang.String or groovy.xml.QName or another object!
String localName = ""
if (name instanceof groovy.xml.QName) {
groovy.xml.QName qname = (groovy.xml.QName) name
localName = qname.getLocalPart()
else {
localName = name.toString()
return localName
