Hi @YassineBk ,

It's impossible to use patch function to update 'Attachments' field.

If the attachment you want to save is from another item's attachment， the best pratice is to save the item's ID to your device and when you online again,you could use flow to get the attachments' content and update it.

If the attachment is from a local device, it will be tricky.

Because when we upload attachment to attachment control, it will generate cache in app.

When we close the app, the cache disappears. So the value of the set will be invalid when you open the app again.

There is a method a bit of hack to get the real file content (base64) of the file.

Add an image control and set its Image property to this value("appres://...")

Then you could add a button and set its onselect property to:

Set(var,JSON(Image.Image,JSONFormat.IncludeBinaryData))

Now, you get the file content . Save it to your local device.

Let's go back to the beginning. We can use this formula to update/create attachments.

Best Regards,

Wearsky
