# Issue with Append data. I can not get all the data when I append. Data disappears one wa

Dear Power Bi Community,

I have built a sales data model and direct connection through the SAP connector (import query). The report / Data model has worked well but now faces some challenges. Maybe you have some solution.


Problem description: I retrieve data a year at a time and subsequently make append in power query. I can not get all the data when I append. Data disappears one way or another. I googled a lot, but I think the problem is either on a date or SAP connector. I do not know if you have experienced a similar problem, but I would like to hear from you. I appreciate any help you can provide.

Hi @Konesan ,


I think you can try deleting the current credential information in the data source setting and then reconnect. Click on the advance option and enter the relevant language code and the custom MDX statement to be run against the specified server



For more details, you can read related document.

If the problem is still not resolved, can you provide relevant screenshot information and describe your steps? Looking forward to your reply.

Hi Henry,

Thank you for your suggestion. It is still not working. I have two issues regarding the SAP connector. Append case – and Power Bi Service.

Here is a screenshot of my log-on credential info:


Issue with Append: I extract data for each year and append it to one table. The number or calculation is not correct after appending it to one table. I work with a workaround solution. Step. I load all three data to the data model and use Dax to “Union” to append my data then everything works fine.


Publish data model to Power Bi, then data disappear someway

Thank you.
