How to subtraction operation Groovy script in insight Post Functions

[kahn chang]

Hi

I have CustomField：
CustomField 10328 is a standard number field
CustomField 10321 Mapping to insight objectType 100

objectTypeAttribute 1004 of insight objectType 100, type=defailt ,type value=integer

I need Update object attribute 1004 with the value “attribute 1004” Minus “CustomField 10328”

I have no experience. I tried to modify Groovy script examples, but I haven't touched on subtraction yet. I made an error.

Please help me!

Hi, 

The createObjectAttributeBeanForObject takes a variable argument of strings as the latest parameter which might not be that intuitive. 

The trace indicates that you got a Double value. 

If you sent the last parameter to the createObjectAttributeBeanForObject as the following

String.valueOf(Math.round(issue.getCustomFieldValue(jiraCustomField)))

It should do the trick and of course you can switch the inner statement for the result of your arithmetic operation. 

Check out if it solves your use case. 

Cheers

hi

Thank you for your answer, but it's too complicated for me. I submitted a new function, because I believe it will be very useful.
