File | Options | Workspace
In Portfolio versions of DPL, you can control whether to automatically load database information (table names and field names) upon file open, not load or to be prompted each time.
When working with DPL and Excel you can choose to embed your DPL Workspace into an Excel file. For more on Embedding Workspaces see Embedding. Check the box if you'd like to save the Excel file upon a DPL Workspace save.
If you make updates to the Excel file that the DPL Workspace is embedded in and then do a File | Save As in Excel, you can choose whether or not to be prompted as to whether DPL should embed the Workspace in the more recent file that's open in Excel.
On File | New
