List of "Next Tasks"

[Pascal Fleury]

Hello,

I have a project with quite a few tasks and lots of dependencies. What I am after is a report where I can see the upcoming tasks that depend only on already 'done' tasks.

I have tried this:

project saison2026 "Saison 2026: «Titel Unbekannt»" 2025-11-15 +17m {
  scenario plan "Plan" {}
}

flags shouldjusthappen

task saison "Saison" {
  priority 1
  scheduling alap

  task proben "Proben" {
    task start  "Proben Start"        { start 2026-06-06 }
    task weekend "Probewochende"      { start 2026-10-11 }
  }

.... many more tasks with dependencies

}

taskreport overview "Overview" {
  columns name, start, end, effort, chart { ${TaskTip} }
  sorttasks tree, plan.priority.up, plan.start.up

  formats html
 
  taskreport next "Next" {
    end ${now}
    hidetask (plan.completed > 99)
    #hideresource ~(is_leaf())
    sorttasks plan.start.up
  }

}

I did not manage to get tj3 to grok any of my hidetask attempts. Right now, I get:

Error: /Users/fleury/OrgFiles-priv/theater-2026.tjp:397: (plan.completed > 99)
Logical expression error: Unknown attribute 'completed' queried

Are there examples of this? The ones I found in the documentation do not seem to work either (https://taskjuggler.org/manual/hidetask.html). 

I am using version 3.8.4 on a Mac if that matters.
