David Carrera del Castillo added a comment - 17/Feb/2023 1:57 PM - edited I wrote this ScriptRunner script in order to automate the rank of the issues depending on the sequence displayed. Thanks @David Waldhans for his snippet, it was so helpful to make this possible. Disclaimer, this is a slow method, so if you use it, you will reach the ScriptRunner timeout (60 seconds) constantly. import org.apache.log4j.Level import com.atlassian.jira.bc.issue.search.SearchService import com.atlassian.jira.component.ComponentAccessor import com.atlassian.jira.issue.search.SearchException import com.atlassian.jira.web.bean.PagerFilter import org.apache.log4j.Level import com.atlassian.jira.issue.Issue import com.atlassian.greenhopper.api.rank.RankService import com.onresolve.scriptrunner.runner.customisers.WithPlugin import com.onresolve.scriptrunner.runner.customisers.JiraAgileBean import com.atlassian.jira.component.ComponentAccessor @WithPlugin( 'com.pyxis.greenhopper.jira' ) @JiraAgileBean RankService rankService def user = ComponentAccessor.jiraAuthenticationContext.loggedInUser def rank = rankService.getRankFields()[0].getIdAsLong() // Set log level to INFO log.setLevel(Level.INFO) // The JQL query you want to search with final jqlSearch = 'project = <your_project> and issuetype = "Master Ticket" and statusCategory != Done' // Parsing the query def searchService = ComponentAccessor.getComponentOfType(SearchService) def parseResult = searchService.parseQuery(user, jqlSearch) if (!parseResult.valid) { log.error( 'Invalid query' ) return null } try { // Perform the query to get the parent issues def results = searchService.search(user, parseResult.query, PagerFilter.unlimitedFilter) def issues = results.results // We now have the list of the parent issues, we will find which ones need to be "re-ranked" issues.each { parentIssue -> // Getting the subtasks Collection subTasks = parentIssue.getSubTaskObjects() // Sorting the subtasks by the displayed sequence List sortedSubTasks = new ArrayList(subTasks.size()) subTasks.each { subtask -> def subTaskLink = ComponentAccessor.issueLinkManager.getInwardLinks(subtask.id).find { it.issueLinkType.name == "jira_subtask_link" } sortedSubTasks[subTaskLink.sequence] = subtask } List visibleSequencedSubtasksList = sortedSubTasks*.key // Getting the same subtasks but ordered by rank to compare with the previous list String rankedSubTasksJql = "PARENT = $parentIssue.key ORDER BY Rank ASC" parseResult = searchService.parseQuery(user, rankedSubTasksJql) results = searchService.search(user, parseResult.query, PagerFilter.unlimitedFilter) def rankedSubtasksList = results.results*.key // Comparing if (visibleSequencedSubtasksList != rankedSubtasksList){ log.info( "Parent $parentIssue.key needs re-rank" ) log.info( "Visible sequence : $visibleSequencedSubtasksList" ) log.info( "Ranked subtasks : $rankedSubtasksList" ) // Ok, let's sort them. // This is a slow method, since it is one call for each subtask. // It could be faster by using rankAfter or rankBefore only on the unordered subtasks. // to improve the api calls. // I recommend to first comment this block to check how many issues need to re-rank. sortedSubTasks.each { subtask -> rankService.rankLast(user, rank, subtask) } } } } catch (SearchException e) { e.printStackTrace() null }

David W. added a comment - 30/Dec/2022 4:14 PM - edited Update: Since Jira seems to sort number values from scripted fields lexically (1, 10, 11, 2...) instead of numerically (1, 2, 3...), I updated the description below to return a string value with a three digit number that is left-padded with zeros. @Matt Parks thanks to your comment I found a solution to do this using a ScriptRunner  scripted field returning a template of type "Text Field (multi-line)". Here is the script for the field: import com.atlassian.jira.component.ComponentAccessor def issueLinkManager = ComponentAccessor.issueLinkManager if (!issue.isSubTask()) { return null } def subTaskLink = issueLinkManager.getInwardLinks(issue.id).find { it.issueLinkType.name == "jira_subtask_link" } return subTaskLink ? String .format( "%03d" , subTaskLink.sequence) : null You do not need to add the field to any screen in order to be able to use it. Just write a JQL query returning the desired sub-tasks and use the scripted field in the ORDER BY clause. Hope this helps!
