Carry constant from one session to another
I have my investments in a small database. There are two tables, one for the various accounts, and another for the investments in each account.
Periodically I update them, every few days or weeks. I may not update them all if they haven't changed. I would like to track the most recent date that I updated any of them and have it print on my reports. The reports may be printed without the data being updated.
A global variable disappears at the end of the session so that won't work. If I use a data field, how do I make it apply across all records and layouts? How do I link it? It doesn't want to appear on a layout unless it is related somehow.
Thank you for your help.
