Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
SYMPTOM:
After users create a dashboard or dossier in Strategy Analytics Desktop with a DSNless connection and In-Memory dataset, the file can be imported into Strategy Web using the “Upload Strategy File” option.
When users try to republish the cube for the dashboard or dossier, they encounter the following error:

Sample Error from the DSSErrors log:
"We could not obtain the data because the database connection or warehouse table is changed. Encountered error: Connect failed. Login failed. Error type: Odbc error. Odbc operation attempted: SQLDriverConnect. [HY000:0; on SQLHANDLE][Strategy][ODBC Oracle Wire Protocol driver]Insufficient information to connect to the data source.”
STEPS TO REPRODUCE:

CAUSE:
This is a known limitation when users save a dashboard or dossier locally on their machine and then upload the file to Strategy Web.
ACTION:
Currently this issue is still being reviewed for feasibility by our Technology team and it is not scoped for any upcoming scheduled Strategy release.
WORKAROUND:
Dashboards and dossiers created in Strategy Analytics Desktop using In-Memory cubes can be shared with other Desktop users, who will be able to republish the cube and enter the credentials for the database connections.
Dashboards and dossiers can also be created in Web and shared with other Web users without needing to replace the credentials for the connection, allowing users to republish the cube without encountering the error.
