Node assignment with MNI

This may help:

...or this:

Thank you but that information didn't help me, I'm trying to use the instanceindex in the Assignment tab too and I'm getting the same error.

It is possible to use the instanceindex to assign a task? I need to do that

How have you got the MNI set up? There's an option called "run one instance for each assignee" and then you can set the assignees to an array.

Here is my configuration, the array contains two group names.

In the assignment tab I'm using this rule:

=pv!array[tp!instanceindex]

Can you try using index function as index(pv!array,tp!instanceindex,"") and see whether this helps?

I'm getting the same error :(

There is a problem with the process TST_MH_POC_MNI. ERROR:An error occurred while evaluating expression: =index(pv!array, tp!instanceindex, "") (Could not find variable 'tp!instanceindex') (Data Inputs)

Is the array an array of users?

Is an array of groups, the task will be assigned to different groups

Have you tried using the "one instance per assignee" and assigning to the list of groups (without using tp!instanceIndex)? It's possible this will assign per user per group, though, and so may not fit your use case.

I have a feeling it's not possible to access tp!instanceIndex in the context of the assignee field, which is why you're seeing the error.

If that doesn't work, you could set it up as you have already (one instance per entry in "array) but use a sub process to wrap the task. You could then pass the full array of groups into the subprocess along with the tp!instanceIndex value, and access the assignee within the subprocess.
