Update Custom Field value with Scriptrunner Script Fields

[RMA]

Hi,

I want to create a script field which calculates a value and depending on the value it should update another custom field. So far I have created following script:

import com.atlassian.jira.bc.issue.IssueService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.issue.customfields.manager.OptionsManager
import com.atlassian.jira.issue.customfields.option.Options
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.issue.Issue
import java.lang.Math

IssueService issueService = ComponentAccessor.getComponent(IssueService)
IssueInputParameters issueInputParameters = issueService.newIssueInputParameters()
def customFieldManager = ComponentAccessor.getComponent(CustomFieldManager)
def optionsManager = ComponentAccessor.getComponent(OptionsManager)
def user = ComponentAccessor.getJiraAuthenticationContext().loggedInUser

def A = getCustomFieldValue("Planned Project hours of work")
def B = getCustomFieldValue("Actual Project hours of work + ETC (hours)")
def result = (B-A)/A
def percent = result * 100

return (Math.floor(percent*100)/100 + "%")

def KPI_Project_Work = getCustomFieldValue("KPI: Project Work")

Options options = optionsManager.getOptions(KPI_Project_Work.getConfigurationSchemes().first().getOneAndOnlyConfig())

if (percent < 10)
{
def selectedOptions = options.findAll {
it.value == "Green"
}.collect {
it.optionId.toString()
}
}

I already get the value of "percent", but when I try to update the field value "KPI_Project_Work", just nothing happens. Can anyone help me out?

Best Regards

Robert

Are you able to update the CF value in the scripted console?

Look at this documentation, it may help

I think that when you put the "return" your code execution ends. 
So, If you want to update or do any other operation, just do it before you return a value.
