Gateway Error - Cannot be added to gateway

[Salma123]

Hi there,

I have configured a corporate gateway that connects to an SQL server and well updated. I recently added an initial dataflow that connects to the same SQL server and uses the same enterprise gateway, and another "staging" dataflow 

I am now getting the error for the second dataflow :

Any help on how to navigate this will be appreciated!
Thanks

here is a same post:

As far as I am aware, currently you cannot use an existing Power BI dataset in dataflows.

With regards to a dataflow, you will have to first refresh the dataflow to get the new data in, before you refresh your Power BI dataset.
