Primary Issues and Solutions:
1. Missing Required ID Field
The most common reason for "Update Item" appearing to run successfully but not updating anything is that you must have the unique ID field specified, and all mandatory fields need to be populated when updating a SharePoint item Data SavvyTom Riha.
Solution: In your "Update Item" action, make sure you're specifying the ID field. Add this to your parameters:
- ID:
items('Foreach')?['ID']
2. Missing Required/Mandatory Fields
When updating an item in a SharePoint list, you need to specify values for all mandatory fields, not just the ones you want to change C# CornerTom Riha.
Solution: Check your SharePoint list settings and include all required fields in your Update Item action, even if you're not changing their values. Use dynamic content to populate them with their current values.
3. Date Format Issues
Your addDays() formula looks correct, but date formatting can cause silent failures.
Solution: Try using this format instead:
formatDateTime(addDays(items('Foreach')?['DueDate'], 7), 'yyyy-MM-ddTHH:mm:ssZ')
4. Team Field Configuration
I notice you have a "Team" field that appears to be a People/Group field. These can be problematic in updates.
Solution: Ensure the Team field is properly formatted. If it's a People field, you might need to use:
items('Foreach')?['Team']?['Email']
Recommended Troubleshooting Steps:
Step 1: Add Error Handling
Add a "Configure run after" setting to your Update Item action to catch failures:
- Click the three dots on your Update Item action
- Select "Settings"
- Check "is failed" and "has timed out" in addition to "is successful"
Step 2: Add Compose Actions for Debugging
Before your Update Item, add "Compose" actions to verify your data:
- Compose 1:
items('Foreach')?['ID'] (to verify you have the ID)
- Compose 2:
items('Foreach')?['DueDate'] (to verify the current date)
- Compose 3:
addDays(items('Foreach')?['DueDate'], 7) (to verify the new date)
Step 3: Simplify the Update
Try updating just one field at a time to isolate the issue:
- First, try updating only the Due Date
- Then try updating only the status
- Once individual updates work, combine them
Step 4: Check SharePoint List Permissions
Ensure your flow has proper permissions to update the SharePoint list and that there are no checkout requirements or version control issues.
Step 5: Use HTTP Request as Alternative
If the standard Update Item continues to fail, you can use HTTP requests to update single columns without requiring all mandatory fields Tom RihaAnnajhaveri.
Try implementing these solutions starting with adding the ID field and required fields to your Update Item action. This resolves the majority of "silent failure" cases with SharePoint updates in Power Automate.
