Reports do not refresh

[TI_RB]

We are having problems with 40% of our reports where they don't refresh. The error is "DM_GWPipeline_Gateway_MashupDataAccessError". We have already refreshed the DW server but it didn't work. The full error is bellow, only changing the name of the tables.

An error occurred while processing the data in the dataset.

Detalhes da falha: The last refresh attempt failed because of an internal service error. This is usually a transient issue. If you try again later and still see this message, contact support.

Hi  @TI_RB ,

Would you mind providing more details? For example, the data source you are using and the connection mode? If it uses a gateway, please make sure your gateway is up to date

Best regards.

@v-xiaoyan-msft , we're using a gateway, personal mode. Our data source is a SQL dw. Does this help?
