Step 4: Get a dataset to add rows into a Power BI table ( Example: Push a dataset into a dashboard)

RuudJeursen

If you're using the same code as the sample's, I guess that the the cause of the problem is in this line in the function GetDataset().

                    //Get the first id
                    datasetId = results["value"][0]["id"];

It would always return the first datasetId instead of the one created in the code if there're more datasets alreay existing.

Change the line to lines

                    //Get the first id
                    //datasetId = results["value"][0]["id"];

                    var datasets = results["value"];

                    foreach (var ds in datasets) {

                        //return the id of the first salesmarketing dataset
                        if (ds["name"] == "SalesMarketing") {
                            datasetId = ds["id"];
                            break;
                        }
                    }
