Best to stick with the error message.
If you want to see what happens when you ignore the error message. Which I’m not condoning. You can try this.
Create a configuration package. Add table 325. Add a filter for something that doesn’t exist on one of the fields. Apply a tick to the “Delete table records before processing” of the configuration package line. Export a excel sheet. It will be blank if you set the filter. Place a dummy value in. Import the excel. Use the apply data button. This will error on your dummy import data - most likely - whilst deleting all the data. Your import could include the one’s you intend on keeping.
Again. Not condoning this. But it is possible. The side effects would need testing.
