I would like to lock a field on a particular layout such that it can be viewed but not changed on that layout. The same field must be entered in the same record, but in a different (previous) layout. Any suggestions?

Thank you,

Jason

Use Accounts & Privileges to setup access to your fields for each account. You can control whether someone can modifiable, viewable or no access on a field by field basis inside the Privilege Set section. When you are defining a Privilege Set, you will find the option for field access in the Records popup menu under custom privileges. Choose a table and then select Limited from the Field Access popup menu.

If you just want to keep all users out of the field in that layout...

In Layout Mode, Control-Click on the field, and go to Field Control > Behavior, and uncheck the box next to "In Browse Mode"

Another good way to display a field's value while not allowing editing is to use a Merge Field in place of a conventional field.
