I need to be able to create simple ad-hoc reports on Pentaho BI using plugins like Pivot4j or Saiku. My data provider is SAP with XML/A interface. So the question is how could I create an OLAP data source that based on XMLA protocol? Or it is possible through Mondrian only?
Any help will be greatly appreciated.

Disclaimer: not a developer, but an analyst looking for solutions
I currently have a DOMO dashboard ready, am looking to port/replicate it on Power BI for another set of users who have the rest of their dashboards on Power BI. Is there a way I can do this?
Found a link with regard to having a writeback connector, is this the right one to go about doing it?:
https://domohelp.domo.com/hc/en-us/articles/360063090013-Power-BI-Writeback-Connector
Another similar(?) question on this forum:
https://community.powerbi.com/t5/Developer/Custom-Connector-with-Token-Refresh/m-p/2320423
The worst case scenario given to me, is to recreate the dashboard directly with the data source used in the DOMO dashboard (which I find the most intuitive as an analyst).
I could be trying to do the opposite of what the user here was trying to do from Power BI to DOMO:
Power BI to DOMO
I see there being two options for your use case, you can move the data out of Domo to Azure / Power BI via the Power BI Write-back Connector, which you have already identified, this can be automated and scheduled like a regular Domo process and is all managed and contained within the Domo UI, or, you could retain your data in Domo and have Power BI query it directly by via the ODBC Data Driver.
The ODBC driver setup creates a DSN (Data Source Name) on your machine which references your Domo instance, allowing you to create queries against Domo directly. You can then connect Power BI to that ODBC Connection.
I believe the visualisations would need to be re-created manually, I'm not aware of a tool that would let you port these across.
This question might not be well researched but I need to find out proper way to implement this solution before starting design.
Question is, Can we consume SSAS MDX query as datasource in Azure Data Factory Linked Service source?
Data factory cannot query SSAS with MDX or DAX, but maybe you can query the source of the SSAS, in a traditional BI architecture it would be a Data Warehouse or a SQL server. This is because SSAS models are meant to be consumed by reporting tools (Power BI, reporting services, etc) and not data integration tools, which serve very different processes.
Cheers!
The supported list of connectors for the Copy activity available as at today is available here:
https://learn.microsoft.com/en-us/azure/data-factory/copy-activity-overview#supported-data-stores-and-formats
It looks like SSAS MDX queries are not included at this point.
ADF v2 supports the running of SSIS packages within ADF pipelines so it may be possible via that route (untested).
Can HANA store all the data carried by SAP BI in HANA "in-memory"?
Are there certain BI tools that are available only in SAP BI and not possible in SAP HANA due to architectural differences in nature of Datawarehouse and Database tools now and in future? If yes, what are those?
How does a SAP BI developer use HANA? Does he write HANA Sql Scripts on SAP BI along with ABAP code for BI customization?
ad 1) Yes it can, but it doesn't have to (dynamic tiering and memory displacement can be used).
ad 2) Datawarehouses and DBMS are two different things, so there are lots of differences. If your question is more directed at whether or not SAP HANA can and will replace SAP BW anytime soon, I recommend the following blog posts:
https://blogs.saphana.com/2012/06/13/does-sap-hana-replace-bw-hint-no/
https://blogs.saphana.com/2012/06/20/does-sap-hana-replace-bw-hint-no-part-2/
https://blogs.saphana.com/2014/04/17/does-sap-hana-replace-bw-hint-still-no/
https://blogs.saphana.com/2015/07/06/sap-hana-replace-bw-hint-no/
ad 3) Yes, that's the case. For example expert routines can often be scripted in SQLScript, thereby avoiding data transfer between HANA server and SAP BW application server.
Can HANA store all the data carried by SAP BI in HANA "in-memory"?
Yes it can store all the data carried by SAP BI. Normally BI will have two databases, the first database is installed by default during the installation (that might be any database e.g DB2, MS SQL Server. If you want to keep the data as HANA you have to manually select it and HANA DB has to be physically installed). This will be used for auditing or running the BI System.
Whereas the other database or second database is where the actual data resides, where we are required to do reporting in BI by taking the database as a source.
Are there certain BI tools that are available only in SAP BI and not possible in SAP HANA due to architectural differences in nature of Datawarehouse and Database tools now and in future? If yes, what are those?
HANA is actually a database, whereas BI is a few reporting tools with various flavours such as webi, crystal.
A connector is required to connect between BI and HANA, if we want to connect only the HANA DB with other tools (you can connect ones such as MS Excel).
How does a SAP BI developer use HANA? Does he write HANA Sql Scripts on SAP BI along with ABAP code for BI customization?
A BI Developer will only use the BI tool and all the features which are there in the BI reporting tool, whereas writing SQL Scripts and HANA ABAP code can be written at a backend database level depending upon the requirements by a consultant called HANA Developer, whose responsibility it is to build models at the backend level and make them available to integrate with BI and allow the HANA model to pull in the BI Reporting tool for reporting purposes.
I'm using Power BI web preview and have SSAS as a data source. When my underlying SSAS tabular data model changes, I don't see my reports or the dataset in Power BI get updated.
Since manually "refreshing" the Power BI data set is not supported as of now, how do I make sure that my Power BI reports are in sync with the latest data?
There's a great blog on the Analysis Service connector here:
http://blogs.msdn.com/b/powerbi/archive/2015/03/11/power-bi-analysis-services-connector-deep-dive.aspx
It includes the top trouble shooting tips. If you're still having problems, please use the "?" at the top of the power bi preview UI to ask for support.

As of now you can use Power BI Gateway, and you will have the option to update cubes on scheduled intervals, or you can live connect as well.
Are you using import or direct query method? If you are using import mode you can set up an schedule refresh for that. If you are using direct query all your data is going to be updated
I want use saiku in Pentaho user console. But i want to create in the ETL (PDI or kettle) all the dimensions and measures and show them in Saiku. I am able to use a kettle step as a DS of a chart from the CDE c-tools. Is posible to use the same approach with Saiku, or is there a way to fill a mondrian scheme with the PDI?
Thanks
