Access codes work. You need to assign an access code to the fields and then assign the proper permissions for that access code either in the user record or function profile record. You'll need to validate the screen if you assign the access code on the screen.

Hi Israel,

It looks like that allows us to keep someone from modifying that field, but it does also prevent them from being able to assign a value in that field with the original setup of the customer. The field we're trying to disallow modification for is the customer category, which we will want set up when the customer is created (it's a mandatory field). The access code appears to block them from being able to set it up in the first place, it also looks like it keeps the values from populating at all. Any ideas?

Thanks,
Heather

So your question is different, you want to allow them to modify the field upon creation but not when modifying the record. For that I believe you’ll need to do write some custom code.

Thank you for your help Israel. You're right, ultimately our question was different than what I proposed. We want them to be able to set that value upon creation but not change it once it has been created. I will work on figuring out if we can get some code to allow this capability in our system.
