How to Set Conditional State Transitions Based on Boolean Field in Azure DevOps WITD XML

Question

I am customizing the workflow for a work item type in Azure DevOps and need to set state transitions based on the value of a boolean custom field (Abc.CustomField). Specifically:

If Abc.CustomField is true, the next state available in state dropdown should be "Done". If Abc.CustomField is false, the next state available in state dropdown should be "Terminated".

Answer 1

Based on your description, you need to set the state value based on the custom work item field value.

To meet your requirement, you can define the conditional-based values and rules in XML Process.

Here is an example: We can use WHEN to set the condition based on the Abc.CustomField

<FIELD name="State" refname="System.State" type="String" reportable="dimension" />
       <ALLOWEDVALUES>  
           <LISTITEM value="New" />  
           <LISTITEM value="Active" />  
           <LISTITEM value="Done" /> 
           <LISTITEM value="Terminated" />  
       </ALLOWEDVALUES>   
       <WHEN field="Abc.CustomField" value="true">  
           <ALLOWEDVALUES>  
               <LISTITEM value="Done" />                
           </ALLOWEDVALUES>  
       </WHEN>  
       <WHEN field="Abc.CustomField" value="false">  
           <ALLOWEDVALUES>  
               <LISTITEM value="Terminated" />                
           </ALLOWEDVALUES>  
       </WHEN>  

</FIELD>  

For more detailed info, you can refer to this doc: Assign conditional-based values and rules

If you are using inherited processes, you can use the Work Item Rule to achieve the same feature.
