Search intent

Help a Power Platform builder understand when to use Power Apps Create a SharePoint item and child tasks from one submit, how to implement it, and what mistakes to avoid before using it in a production business app.

Problem

Child rows cannot be reliably created until the parent SharePoint item exists and the app has its new ID.

What the finished pattern should include

  • A maker can explain the control, formula, validation, and save behavior before release.
  • The app gives users clear feedback for successful saves, missing values, and failed updates.
  • The pattern can be handed to another builder without relying on hidden assumptions.

Solution

Formula / code
Set(
    savedRequest,
    Patch(Requests, Defaults(Requests), { Title: txtTitle.Value })
);

ForAll(
    colTaskTemplates,
    Patch(
        RequestTasks,
        Defaults(RequestTasks),
        {
            Title: ThisRecord.Title,
            RequestId: savedRequest.ID,
            Status: { Value: "Not Started" }
        }
    )
)

Implementation checklist

  • Confirm the Power Apps scenario and the business user this pattern supports.
  • Identify the data source, owner, security model, and exception path before building.
  • Build the smallest reusable version first, then add optional branches or polish.
  • Test with realistic data, permissions, edge cases, and handoff expectations.
  • Link this pattern to its collection, topic hub, and related implementation patterns.

Step-by-step instructions

  • Patch the parent item and store the result.
  • Use the returned parent ID for child rows.
  • Loop through the task template collection.
  • Create each child task with the parent ID and starter status.

When to use

  • Request intake with generated tasks
  • Project checklist creation
  • Approval preparation rows

When not to use

  • Simple single-list forms
  • Workflows needing transactional rollback

Common mistakes

  • Using LastSubmit from the wrong form.
  • Creating child rows before the parent item returns.
  • Saving parent title instead of parent ID.

Troubleshooting

  • If child rows are orphaned, inspect the savedRequest variable immediately after parent Patch.
  • If duplicates appear, ensure the submit button is disabled during save.
