Calculating fields using Jira automation

[Emily Bleything]

Hello,

I am trying to use automation to calculate a field I have created (RICE).

The calculation is Reach x Impact x confidence/Effort.

I have tried using this logic 

{{#=}}{{issue.fields.reach}} * {{issue.fields.impact}} * {{issue.fields.confidence}} / {{issue.fields.effort}} {{/}}

I keep getting errors  saying I have an unknown operator * at the character position. Does anyone know if I am missing something?

Hi Emily,

It looks like you are missing a value (field is probably empty) and it is not handling that. Seems to be the field called Impact. 

I would check the value of all of those fields for the issue it is running against so make sure none are empty.

I would also setup a default value for each field so that in the future you don't run into the same error.

Thank you John, I think that has solved an issue , but I am now getting an error on missing parameters. Please could you advise?

[John Funk]

I don't think it will make a difference, but you don't need the word "fields" in there. Just take it out. 

If no difference, can you share the entire rule?

Hi John, 

 I noticed we had another custom field called 'Impact' which was not a numeric field and I must have selected the wrong one in my rule. Added the correct one and it's working now. Thank you for your help :) 

[John Funk]

Great! Glad you figured it out.  :-)

@Emily Bleything , thanks so much for this info.  It helped me tremendously.

Hi All,

I have a similar problem with the same error, but the resolution eludes me.
It seems that I have multiple custom fields but I have no control what is being selected from the dropdown (when/where value change is monitored).

two questions came to my mind:
1 - what type the custom field has to be (I'm assuming number)

2 - is there a way to manage custom fields and remove the unused ones?

[Peter Revay]

when I select the field, only one appears from these above

Hi Emily, 

I am looking to implement a similar automation, would you be able to share a screenshot of your flow?

Thanks

Hi Alex, 

I created the rule for RICE scoring using this method (I created 4 custom fields first) Hope this helps.

Rice Score = {{#=}}{{issue.reach}} * {{issue.impact}} * {{issue.confidence}}/{{issue.effort}}{{/}}

Hi @Emily Bleything  Is there a way to do this based on the non numeric fields? Can I assign a dummy variable say impact = 2 if the value is low, 4 if high etc. and then calculate the Rice Score using the variable?

hey @Vikas Gupta  @Emily Bleything ... were you able to find a way to achieve this ? Have a value for the dropdown list label ?
