Can a EDQ Process perform looping ?

Question

Hello,
I want to create a looping process in EDQ. Here is the scenario..
Reader based on a snapshot/data store.
1. Process reads one record at a time from Reader.
2. For each record,
      a. Call an external web-service (inserts the record in CRMOD, and returns Row-Id)**,
      b. Writes the record + CRMOD.Row_ID to a Writer (CSV file),
      c. Return to Reader and pick up the next record,
    Until No more records.
**I have already created the custom script processor for the CRMOD web-service and it works.
Is this type of flow even possible in EDQ ?
Thanks in advance.

Hi Nick,
Thanks for your response. Yes I have written a process. The process has two processors. I have attached the dxi.
1. Reader - Reads 100 records from snapshot (based on csv file)
2. Script Processor - takes input (four fields), calls CRMOD query web service and performs query on the four fields, returns CRMOD data.
The problem is, EDQ is flooding CRMOD and maxing out the concurrent session limit - 100 records get to CRMOD so quickly that they end up being too many concurrent sessions in CRMOD, which has limit of 5 concurrent sessions for this particular account.
So my thought was - Don't process next record in EDQ until the current transaction has completed (so we maintain only one concurrent session in CRMOD).
Here is my script..
addLibrary("http");
function GetValue(content, name) {
  var value = "";
  var startPos = content.indexOf("<" + name + ">");
  if (startPos > -1) {
   var endPos = content.indexOf("</" + name + ">", startPos);
value = content.substring(startPos + name.length + 2, endPos);
  return value;
try {
var result = new Array();
var inputFN = input1[0];
var inputMN = input1[1];
var inputLN = input1[2];
var inputEmail = input1[3];
var inputTitle = input1[4];
var url = "https://secure-slsomxuda.crmondemand.com/Services/Integration";
var xmlHttp = new XMLHttpRequest();
xmlHttp.open("POST", url, false); ---------------------- false = synchronous session ------------------------------
var request = "<?xml version='1.0' encoding='UTF-8' ?>" +
           " <soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:con='urn:crmondemand/ws/contact/' xmlns:con1='urn:/crmondemand/xml/contact'>" +
    " <soapenv:Header>" +
       " <wsse:Security xmlns:wsse='http://schemas.xmlsoap.org/ws/2002/04/secext'>" +
            " <wsse:UsernameToken>" +
               " <wsse:Username>xxx</wsse:Username>" +
               " <wsse:Password Type='wsse:PasswordText'>xxx</wsse:Password>" +
            " </wsse:UsernameToken>" +
       " </wsse:Security>" +
    " </soapenv:Header>" +
    " <soapenv:Body>" +
       "<con:ContactWS_ContactQueryPage_Input>" +
          "<con1:ListOfContact>" +
             "<con1:Contact>" +
                       "<con1:ContactId></con1:ContactId>" +
                "<con1:ContactEmail>='" + inputEmail + "'</con1:ContactEmail>" +
                "<con1:ContactFirstName>='" + inputFN + "'</con1:ContactFirstName>" +
                "<con1:JobTitle>='" + inputTitle + "'</con1:JobTitle>" +
                "<con1:ContactLastName>= '" + inputLN + "'</con1:ContactLastName>" +
                "<con1:MiddleName>='" + inputMN + "'</con1:MiddleName>" +
              "</con1:Contact>" +
          "</con1:ListOfContact>" +
       "</con:ContactWS_ContactQueryPage_Input>" +
    "</soapenv:Body>" +
"</soapenv:Envelope>";
    xmlHttp.setRequestHeader("SOAPAction", "\"document/urn:crmondemand/ws/contact/:ContactQueryPage\"");
    xmlHttp.send(request);
    var response = "" + xmlHttp.responseXML;
    var result = new String();
    var startPos = response.indexOf("<Contact>");
    while (startPos > -1)
       var endPos = response.indexOf("</Contact>", startPos);
       var record = response.substring(startPos, endPos);
       var conid = GetValue(record, "ContactId");
       result = conid;
       startPos = response.indexOf("<Contact>", endPos);
     if (startPos = response.indexOf("SBL-ODU-01003") > -1)
            { result = "Session Limit Reached";}
catch (e) {
    result = "Error: " + e.toString();
output1 = result;
Thanks,
Deepak.
