Dataflow refresh failing without details
I think I found the problem by my own.
I found some blog post (couldn't find the URL anymore) which pointed me into the direction of the default page size settings of Navision OData service. This is set to 1000 in Dynamics NAV 2013. And Power BI simply can't handle this pagination...(holy c***)...
So:
- increased pages setting in NAV service on server + restarted service (Dynamics, not data gateway!)
- refresh query (Power BI Desktop test) + refresh dataflow => works
Something more like a bug than wanted behaviour, isn't it?
Community SupportHi mafl089 ,
Could you please try to reproduce this issue with the latest On-Premises Data Gateway? Have you tried to run this same query on Power BI Desktop to see if the query is working fine? What is the last time the query refresh success? Please also check the machine running this gateway can access the data source.
Best regards,
Hi v-lid-msft,
thanks for your reply.
Accessing the query in powerbi.com works, I do get data in the query and can add tasks / steps. Only the refresh of the entity fails.
When adding the Source directly in Power BI Desktop it is nearly the same: I see data and can edit it as well in the Query Editor, but when applying I get:
ItemListe_Q
Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] An error was read from the payload. See the 'Error' property for more details..
'.But I can't find anything within PowerBi Desktop to get more out of it, because there is no error before applying the Query and when Applying I get this error in an Popup.
We already have latest data gateway build installed and accessing the OData URL from data gateway server is checked.
Best,
Matthias
