SOAP UI multiple times to run a test case

DataSource Loop makes it easier to run multiple test cases.. And this feature you can get once you buy the license. Otherwise,, You need to write java/groovy code to implement this. You can give a try using for loop :-

def ds = testRunner.testCase.getTestStepByName('DataSource')
def totalRow = 5
def col1, col2, col3
def request = ""

for (row in 1..totalRow) {
 if (row > 1) {
  testRunner.testCase.getTestStepByName('DataSource').next(testRunner, context)
 }
 col1= ds.getPropertyValue('col1')
 col2= ds.getPropertyValue('col2')
 request += "<column1>${col1}</column1><column2>${col2}</column2>" 
}

 This way you need to write codes which is really tough to handle.
