yes the field names can change. Here's an example of the letterhead
ok you're the Director of the office and your name is on top of the letterhead which is deplayed by a field name from a view. Also at the botttom of the letterhead your name is displayed again along with your Electronic signature, b/c we've stored a blob of signature.
Now let's say 6 mos down the road you resign and I take your place. Now instead of going into CR to make modifications I have an external client that will automatically make the changes for me to the CR. In order for my Name and elec. signature is displayed on the report.
