ODBC DataSource.Error when expanding a table
We want to analyze data from UNIT4 Multivers Online system using ODBC using the UNIT4 Multivers Online ODBC-driver. Using the Power BI ODBC connector we want to import the UNIT4 data. After setting up the connection we see tables inside the system, but when we click on a table to expand it we get an ODBC error. What is the best step to do to resolve this issue?
Error message:
DataSource.Error: ODBC: ERROR [UNIT4] An error occurred on the server
Details:
DataSourceKind=Odbc
DataSourcePath=dsn=UNIT4 Multivers Online
OdbcErrors=Table

Hi haroldvandekamp,
I got below information internally:
We do quite a few operations against the driver which Excel does not do. In this case, we’re trying to get the primary keys for schema: SYSADM, table: DEBITEUR and the server is returning an error. This may indicate a bug in the driver or that the user is missing certain permissions on the server which are necessary to get the primary keys of the table.

Hi haroldvandekamp,
1. Please check if the error occurs when you expand data from this specific table or any other tables.
2. Check if the issue related to Power BI desktop. You can get data use ODBC data source in Excel to see if data can be retrieved.
3. Please update the Power BI desktop to the latest version.

Hi Qiuyun Yu,
Thank you for the reply.
- Yes, it happens for each table shown in the screenshot
- Retrieving the data using ODBC in Excel works
- We are using the latest Power BI Desktop version, we updated it yesterday to the latest version
