How to transition from one state to another with specific field value check

Question

I would like to do some pre checks on the particular field value before moving to another state. I have Field called sub-status which need have particular value before it move to new state. How do I do this precheck or conditional transition of a workitem ?

Please give some ideas on this and is appreciated

 

Answer 1

Hi Vinay,

You can use the Work item Field rules. But in your scenario you are mentioning the particular value which i doubt. You can make that field as required (using REQUIRED rule) or you can assign a new value (Using COPY rule). If possible could you please explain me the scenario in detail.

Best regards,

Chandra

You have to make your substate required and work with the WHEN and ALLOWEDVALUES rules.

Thanks Chandra,

To explain bit more, I have states from New->Open->Dev->QA->Closed. Also I have substate mapped to each main state. For Example 'New' state has mapped to two sub state called 'In Analysis' and 'Reviewed'. I would like to allow next state (i.e Open) only when main state has substate 'Reviewed' (New, Reviewed).

Thanks Ewald,

I have already done REQUIRED, WHEN ALLOWEDVALUES. I am able to map substate depending on the main state. But, I would like to do is allow next state only during perticuler main and substate combination.

Answer 5

Hi Vinay,

You can use the below code snippet to achieve your scenario.

<FIELD name="State" refname="System.State" type="String" reportable="dimension">
        <WHEN value="In Analysis" field="Custom.substate">
          <READONLY />
        </WHEN>
</FIELD>

 I made the system.state "readonly" when the "custom.substate" value is "In Analysis". This will not allow the users to change the state of the work item when the Custom.substate is "In Analysis". You can change the state when the value is "Reviewed". I hope this will help you in achieving your scenario.

Best regards,

Answer 7

Hi Chandra,

I found a problem when I change the state and Substate. It makes State READONLY but I am not able to save. Message shows "The Value for the Field 'State' is must be the same as the original value". It expects the previous state value. So, I am not able to move to new state.

Hi Vinay,

For System.state a rule REQUIRED is applied by default. Let me check once and will give you the update.
