Help for DSU0438

You have specified to replace an existing physical database file. If this file contains data, when it is compiled the data will be lost because a compile always generates an empty file.

Response: Select Yes to cancel this action so the data is not lost. You can then compile to another new file, and use the OS/400 Copy File (CPYF) command to copy the data into the new file.

Select No to continue anyway and delete the old file and its data.
