PBi Service - Dataset failed to refresh

[MajeedKhan]

In our PBi service, everything was working fine until last week, I am getting errors on dataset update on miscellaneous reports. 

pbix file size is about 470 mb. 

The error:

Data source error: {"error":{"code":"DM_GWPipeline_Gateway_TimeoutError","pbi.error":{"code":"DM_GWPipeline_Gateway_TimeoutError","parameters":{},"details":[],"exceptionCulprit":1}}} Table: retail RETAILTRANSTABLE.

Hi @MajeedKhan ,

This is a gateway timeout error. Please check if the solutions in the following threads can help you solve problem:

In addition, if the data model is very complex or the size of dataset is very large, it might cause timeout error. So please try to optimize the data model and reduce the size of dataset.
