how can use filter on child level object

[Rashree138]

HI Team,

How can we use filter on child level object using WF api call.

like project have task collection and need a filter on tasks:milestoneID

I am using below code:

/attask/api/v19.0/PROJ/search?ID=XXXXX&fields=tasks:milestoneID&tasks:milestoneID_Mod=notnull

result is i m getting all the tasks list filter is not applying. 

what is wrong on above code.

I think maybe just go with

_____________&tasks:milestoneID_Mod=notnull

if you're looking to pull projects where tasks have milestones.

If you're looking to pull specific task data, might be easier for you to do /task/search?projectID=XXXXX&milestoneID_Mod=notnull&fields=* (why are you being constrained to a project search?)

Thanks for reply...

My requirement is to pull all projects details along with its associated tasks and where milestoneID is not null.

sorry I don't understand your goal. Are you being asked to pull in tasks where milestoneID is not null, or ALL tasks in the project?

Project having collection of tasks and I want to pull all tasks where milestoneID is not null under project.

Can you just do 

/attask/api/v19.0/task/search?projectID=XXXXX&milestoneID_Mod=notnull&fields=project:*
