AssignVariable value in RaisFault not setting up dynamically

I want to set a variable value dynamically in in RaiseFault Policy. for example -

<AssignVariable>
  <Name>raiseFaultSource</Name>
  <Value>{someflowvariable}</Value>
</AssignVariable>

so that I can use “raiseFaultSource” variable value in fault rules. is it possible?

Everything in Value is taken as string literal.

I have tried using to reference flow variable, but it doesn’t work as well.

Found that using without {} is working. so -

<AssignVariable>
  <Name>raiseFaultSource</Name>
  <Ref>someflowvariable</Ref>
</AssignVariable>

Yes, and if you want a full message template, then you can use the Template element:

<AssignVariable>
  <Name>nameOfVariableToSet</Name>
  <Template>{FlowVar1}.{FlowVar2}.foobar.{FlowVar3}</Template>
</AssignVariable>

With AssignVariable, there are 3 options:

  • Value - sets a string literal
  • Ref - assign the value of one variable to another variable
  • Template - assign the result of a message template to a variable
