RE: Scan question

I think it would be a bad idea for a record to change the SCAN field.
That is something that you should let the database designer do.  They
may want to use your record in ways you never thought of.

However, if you really want your record to process again when something
happens then the record code can request reprocessing without changing
the SCAN field.  There are several ways to do this (scanOnce,
processRequestProcessCallback) depending on the application.  Look at
the Application Developer's Guide.
