Make a scripted field multiply together the values of 3 custom fields

[Daniel_Howard]

I have 3 custom fields with the values of say  3, 7 & 8 - I want to stop the need for our 4th field to be manually updated by multiplying together these 3 values.

How can I create a scripted field that does the following

CustomFieldA * CustomFieldB * CustomFieldC  = CustomFieldD (the scripted field)

[Leonard Chew]

I gather you are using scriptrunner?

If so, this should do the job:

Create the Scripted Field "CustomFieldD" with this script:

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def CustomFieldA = customFieldManager.getCustomFieldObjectsByName("CustomFieldA")[0]
def CustomFieldB = customFieldManager.getCustomFieldObjectsByName("CustomFieldB")[0]
def CustomFieldC = customFieldManager.getCustomFieldObjectsByName("CustomFieldC")[0]

def CustomFieldAValue = (issue.getCustomFieldValue(CustomFieldA) ?: 0) as float 
def CustomFieldBValue = (issue.getCustomFieldValue(CustomFieldB) ?: 0) as float 
def CustomFieldCValue = (issue.getCustomFieldValue(CustomFieldC) ?: 0) as float

return (CustomFieldAValue * CustomFieldBValue * CustomFieldCValue)

Thanks for the update, so if I insert the fields like so - each of the fields are named below - they will have a value of 1 to 10.. tried this but the number field is not calculating?

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def CustomFieldA = customFieldManager.getCustomFieldObjectsByName("FMEA Severity")[0]
def CustomFieldB = customFieldManager.getCustomFieldObjectsByName("Detectability")[0]
def CustomFieldC = customFieldManager.getCustomFieldObjectsByName("Occurrence")[0]

def CustomFieldAValue = (issue.getCustomFieldValue(CustomFieldA) ?: 0) as float
def CustomFieldBValue = (issue.getCustomFieldValue(CustomFieldB) ?: 0) as float
def CustomFieldCValue = (issue.getCustomFieldValue(CustomFieldC) ?: 0) as float

return (CustomFieldAValue * CustomFieldBValue * CustomFieldCValue)

What error do you get?

OK, it has problems with casting the value '10' to float. 

Can you go to the Custom Fields Admin page and check the field types of the fields  'FMEA Severity', 'Detectability' and 'Occurrence'?

The field type should be 'Number Field' for all three fields.

Hi @Leonard Chew , thanks for the script.  It works when I want to multiply two number custom fields.

Do you know how to make it work when multiplying a number custom field with another scripted field?  I tried this, but it did not return the product.  My case:

• First field is a custom number field (no problem)
• Second field is a scripted number field (an existing Scriptrunner calculated field)
• ScriptedField2 = CustomFieldA * ScriptedField1

However, when I multiply the two, it always returns zero, and I think it is because the script does not like the second field.  Is there a syntax update to recognize the second field?      

Thanks.

@Inayat N In ScriptField1, use a dedicated Method that returns the correct value (store it with the Script Editor on your Server).

In ScrpitedField2 use the same stored Method to multiply with CustomFieldA.

Alternatively you can copy-paste the code of ScriptedField1 into your ScriptedField2, but you have to be careful when doing changes, as the changes will need to be done in both scripts.
