Could you share more details about your scenario? how did you create the Dataflow? how was the Default destination set? what Fabric item did you set as your default destination?

At the moment, Default destination set an automatic update method for each destination and each one relies on the capabilities of the destination:

Here's a screenshot of the section in that article that calls out the expected behaviors:

I got my answer , the issue was , if we set default destination as warehouse in a dataflow then fabric every time appends the data we cant change the update method to replace in this case. To use update method as replace, we need to set destination for each table manually. Thanks @miguel
