Probem on report after change Data Source type

We work with a product that can work in Oracle or SQL Server DB. Power BI access to this DB to extract information in Import data mode. Our goal now is to create some template report than can work in booth DB only changing the data source from Oracle to SQL Server.

 

The problem we're facing is: When we change the data source type, from Oracle to SQL Server(using PQ Editor -> Advance Editor), Power BI is not able to re-paint properly the report. The graphical object appear like unproperly configure and don´t re-paint. In example, a bar graph with a Total Sales and client is not able to re-paint because don´t find Total Sales column in the new database, event the name of the column is the same. When I remove the incorrect fields and choose the correct one its works fine but this is not the idea.

 

Can anyone give us an idea about how to solve the problem?

 

Thanks in advance.

Thanks for your help.

I found a solution to my problem. I created an Oracle view (and the equivalent in SQL Server) with all the information than I need in my report. Them, in the report instead to select the tables involves, I select directly to the view typing the name of the fields of the query in the select section rather than use select *. After that, I change the DB source from Oracle to SQL Server (or vice-versa) and everything looks to be working fine. I Still haven´t tested enough but my first test case works.

Anyway, here is my actual M-Script code:

 

-Oracle:

    let
    Origen = Oracle.Database("OracleHarina", [HierarchicalNavigation=true, Query="select COMPANY, PRODUCT, PRODUCTTYPE, TOT_VOL, VOLUMEUNIT from V_TEST_VIEW"])
    in
    Origen

(OracleHarina is the entry name in tnsnames.ora)

 

-SQLS:

    let
    Origen = Sql.Database("42.112.110.220", "demoharina", [HierarchicalNavigation=true, Query="select COMPANY, PRODUCT, PRODUCTTYPE, TOT_VOL, VOLUMEUNIT from V_TEST_VIEW"])
    in
    Origen

 

Thanks in advance!!

Hi @AngelQ ,

 

could you post your M-Script (Advance Editor) ?

Both versions, the SQL Server version and the Oracle corrected version.
