I routinely import databases from Excel with a particular model. I am finding that data in some fields is being truncated. I have the display width saved as 15 and still get character strings of lesser lengths truncated.
I had tried to change the data length by double-clicking on the Column Heading and adjusting the field properties and it did nothing. But when you said that again, I thought about adjusting the data length in the Field List and voila. Perfect.
