Nested Loops and API calls

[v-xida-msft]

Hi @jernejp ,

Do you want to use the AddedActivity (rather than AllActivities) within yout second loop?

Based on the needs that you mentioned, I afraid that a triple nested loop could not achieve your needs. Please consider take a try with above solution I provided.

On your side, you could consider create a ForAll loop firstly to retrieve all added activities using the following formula:

ForAll(
    AllActivities;
    Collect(
        AddedActivity;
        'MyApi'.AddActivitiesToBusinessPartner(
            {
	    }
        )
    )
)

Then add another ForAll loop to go through the all attendees that attended the activity, and add them to above retrieved added activities using following formula:

ForAll(
         AddedActivity,
         ForAll(
                Filter(
                        '[dbo].[attendees]';
                        activity_id = AddedActivity[@id]
                );
                'MyApi'.AddAttendantsToAnExistingActivity(
                {
                  ....
                }
              )
         )
)

So your whole formula should look like below:

ForAll(                   /* <-- Seperated ForAll Loop */
    AllActivities;
    Collect(
        AddedActivity;
        'MyApi'.AddActivitiesToBusinessPartner(
            {
	    }
        )
    )
);;
ForAll(                          /* <-- Nested ForAll Loop */
         AddedActivity;
         ForAll(
                Filter(
                        '[dbo].[attendees]';
                        activity_id = AddedActivity[@id]
                );
                'MyApi'.AddAttendantsToAnExistingActivity(
                {
                  ....
                }
              )
         )
)

Please take a try with above solution, check if the issue is solved.

Hi @v-xida-msft 

The problem is, that in my AllActivities, the ID of activity would be (for example) 60 (as it's taken from my database), but from ERP, the response is an id of (for example) 4000231. So If I understand correctly, the second (nested) loop wouldn't work, because 'activity_id' is not the same as AddedActivity[@id].

Could I add a column to AddedActivity in the first loop, and add AllActivities[@id] to it? How would I go about that? I think if I can add the database's ID of activity to AddedActivity, then the second loop would be finished, right?
Hope I'm making sense

Hi @jernejp ,

Yeah, you are right. I have made a test on my side, please consider take a try with the following formula:

ForAll(                   /* <-- Seperated ForAll Loop */
    AllActivities;
    Collect(
        AddedActivity;
        {
           ActivityID: AllActivities[@id],                /* <-- add a column to store the id value from the AllActivities */
           ResponseRecord: 'MyApi'.AddActivitiesToBusinessPartner( { ... } )
        }
    )
);;
ForAll(                          /* <-- Nested ForAll Loop */
         AddedActivity;
         ForAll(
                Filter(
                        '[dbo].[attendees]';
                        activity_id = AddedActivity[@ActivityID]
                );
                'MyApi'.AddAttendantsToAnExistingActivity(
                {
                  ....
                }
              )
         )
)

Please consider take a try with above formula, check if it could help in your scenario.
