Paginated Report Builder Oracle Data Source Connectivity issues
i had same problem on 64bit laptop
i found this: https://docs.microsoft.com/en-us/sql/reporting-services/report-data/oracle-connection-type-ssrs?view=sql-server-ver15
after doing these steps
32-bit drivers for Report Builder
Report Builder uses Managed ODP.NET for authoring paginated reports. The following steps are only needed when using Oracle ODAC drivers 12.2 and later as they install by default to a non-machine-wide configuration for a new Oracle home installation. These steps assume you've installed the ODAC 18.x files to c:\oracle32 and the file version of your Oracle.ManagedDataAccess.dll is 4.122.18.3.
On the Oracle download site, install the oracle 32 bit odac Oracle UI
Register ODP.NET Managed Client to GAC:
C:\oracle32\product\18.0.0\client_1\odp.net\bin\4\OraProvCfg.exe /action:gac /providerpath:C:\oracle32\product\18.0.0\client_1\odp.net\managed\common\Oracle.ManagedDataAccess.dll
Add ODP.NET Managed Client entries to machine.config:
C:\oracle32\product\18.0.0\client_1\odp.net\bin\4\OraProvCfg.exe /action:config /force /product:odpm /frameworkversion:v4.0.30319 /productversion:4.122.18.3
Then i added all my oracles connections into TNSNAMESORA and PBI report builder works fine now for oracle connections
