From groovyinsoapui.wordpress.com :
Accessing variable values on the go while sending SOAP request to some service, might solve many problems at times. In SOAP UI, there are two ways to accomplish this
i) Using ‘Property Transfer’ step
ii) Using ‘Property Expansion’ accordingly wherever required. Here I am explaining this procedure fo accesing properties.
${#Scope#Property-name[#xpath-expression]}
${Property-name} refers to a Global Property
(example: ${UserName} to a global Property named “UserName”)
${#Project#Property-name}refers to a Project Property
(example: ${#Project#UserName} to a Property on Project level named “UserName”)
${#TestSuite#Property-name} refers to a TestSuite Property
(example: ${#TestSuite#UserName} to a Prop on TestSuite level named “UserName”)
${#TestCase#Property-name} refers to a TestCase Property
(example: ${#TestCase#UserName} to a Prop on TestCase level named “UserName”)
${TestStep-name#Property-name} refers to a property in a named TestStep.
