SoapUI NG Pro and a Large Test Suite

I am trying to implement a datasource method to test, and am using this with a request. I add the datasource, import my data, verify it is there, and then go to my request. In my request I right click and say "Get Data" but the Datasource does not show up. All that shows up for options for getting data from is my project and my test suite. Why would this be?

/**
* Below script shows how to build xml using MarkupBuiler with easily 
* using element names as need by the user
* just like how xml appears
* (as shown in color code;elements, data)
**/

import groovy.xml.StreamingMarkupBuilder
import groovy.xml.XmlUtil

//Define all your namespaces here
def nameSpacesMap = [
soap: 'http://schemas.xmlsoap.org/soap/envelope/',
ns: 'http://www.domain1.example.com/person',
ns1: 'http://www.domain2.example.com/student',
xsi: 'http://www.w3.org/2001/XMLSchema-instance'
]

//For instance, let us assume the data read[record] 
//from datasource
def name = 'John'
def age = 20
def type = 'Student'
def education
def adress


//How the request can be built. Optionally you can put the 
//below code snippet into a function and pass the data 
//to it, then retun the request as String like this
/*
* def createRequest(parameter1...parametern){
*   //below code goes here and have below line be the last line of function
*   // so that will convert it into String
*  return XmlUtil.serialize(soapRequest)
*/

def builder = new StreamingMarkupBuilder()
builder.encoding ='utf-8'
def soapRequest = builder.bind {
    mkp.xmlDeclaration()
    namespaces << nameSpacesMap
   
    soap.Envelope {
        soap.Body {
            //example for element attribute
            ns.UserRequest (type:type){
                ns1.name(name)
                ns1.age(age)
                //add education element irrespective of data
                ns1.education(education)
                //add address only if there is data
                if(!address) {
                    ns1.address(address)
                }
            }
        }
    }
}

Output will be
----------------------------------------------------------------
<?xml version='1.0' encoding='utf-8'?>
<soap:Envelope xmlns:ns="http://www.domain1.example.com/person" 
               xmlns:ns1="http://www.domain2.example.com/student" 
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<soap:Body>
		<ns:UserRequest type="Student">
			<ns1:name>John</ns1:name>
			<ns1:age>20</ns1:age>
			<ns1:education/>
		</ns:UserRequest>
	</soap:Body>
</soap:Envelope>

Click here to see the script and execute.

This is how a dynamic request can be created(using groovy step) with optional element(with if condition), optional data without data(education).

Once that is done you can set the request[soapRequest object will have above output] to next soap request step.

Hope this is helpful.
