You are deploying the Research model. You need to ensure that the data contained in the model can be refreshed. What should you do?

Importing the workbook into a new tabular database creates an entirely separate model and does not enable refresh of the existing Research model.

When Analysis Services processes a tabular model, the Windows service account running the Tabular instance is the identity used to connect to data sources. Granting that service account read access to MarketResearch.xlsx on the network share allows the engine to open the file during scheduled or on-demand refresh without authentication errors.

Creating an SSIS package adds unnecessary complexity and an extra ETL layer; the tabular engine can read Excel files directly once the service account has the required file permissions.

Uploading the file to a SharePoint library changes its location but does not grant the Tabular instance service account the permissions it needs to access the file during processing.
