Trigger pipeline with jobs from another pipeline - azure-devops

Question

I need to develop two azure devops pipelines. 'Starter.yml' - is trigger for second one. 'Processing.yml' - has some business logic.
Very important thing: both of them must have jobs.
I tried doing something like this:
Starter:
trigger: none
pool:
vmImage: 'windows-2019'
stages:
- stage: A
jobs:
- job: Triggering
steps:
- template: Processing.yml
Processing:
jobs:
- job: Processing
steps:
- task: PowerShell#2
inputs:
targetType: 'inline'
script: |
# Write your PowerShell commands here.
Write-Host "Hello World"
I get following result:
I saw a lot of examples but all of them dont work. Of course I have parallel jobs:
Is it generally possible to trigger pipeline from another pipeline when both of them have jobs?
Thank you for your answers.

Answer 1

Thanks everyone for their answers, I managed to do what I wanted:
In following example:
There are two pipelines ('Starter' and 'Processing')
'Starter' gets input parameters in variables
'Starter' triggers 'Processing' (- template: Processing.yml) and passes input parameters to it (parameters: firstName: $(FirsName))
Processing uses the parameters (${{parameters.firstName}})
Starter
trigger: none
pool:
vmImage: 'windows-2019'
stages:
- stage: A
jobs:
- template: Processing.yml
parameters:
firstName: $(FirsName)
lastName: $(LastName)
- job: Finishing
steps:
- task: PowerShell#2
inputs:
targetType: 'inline'
script: |
# Write your PowerShell commands here.
Write-Host "Finished"
Processing
parameters:
- name: firstName
default: ''
- name: lastName
default: ''
jobs:
- job: Processing
pool:
vmImage: 'windows-2019'
steps:
- task: PowerShell#2
inputs:
targetType: 'inline'
script: |
# Write your PowerShell commands here.
Write-Host "Hello from second pipeline ${{parameters.firstName}}"
For using parallel jobs you have to buy microsoft-hosted parallel jobs (settings of your project):
