SAP Business Warehouse: Object reference not set to an instance of an object.

Hi Anonymous ,

From a similar issue:

This error is usually happens due to presence of empty cells don’t have null value. To figure out which sheet contains these cells, refresh the file. During the refresh, the error will appear in the culprit sheet saying for example “Customers sheet contains empty cells in the emails column”.

You have to fill these cells either with null value or the missing data.

If you still cannot solve the issue,sorry for that, we do not found an effective solution.
We suggest you go to https://powerbi.microsoft.com/en-us/support/ ,scroll down and click "CREATE SUPPORT TICKET" for further help if you are a pro user.
