  • 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
Patch(
    Requests,
    selectedRequest,
    {
        Department: {
            Id: cmbDepartment.Selected.ID,
            Value: cmbDepartment.Selected.Title
        }
    }
)

  • Link this pattern to its collection, topic hub, and related implementation patterns.

Step-by-step instructions

  • Load the lookup source into the combo box.
  • Confirm the selected record includes ID and Title.
  • Patch Id and Value together.
  • Test with a new item and an edit item.

When to use

  • Department lookups

When not to use

  • Large lookup lists where delegation needs special handling
