New custom JQL function for JIRA 7.x to filter the TOP ROWS of a Query! Very useful! By default filters the TOP 10 rows. The JQL function is writed in Groovy and deployed with Adaptavist Scriptrunner.

Syntax example: (to extract the top 20 rows of a project called JIRA)

issuefunction in TopRows( “project = JIRA ORDER BY Key DESC”, 20)

How to deploy in the Server? See the post How to add new custom JQL Function with ScriptRunner
