Goal: Define new DFF segment in Transactions Form and make it read only to Receivables Manager responsibility. All other responsibilities will have access to enter and edit the values and Receivables Manager will have access to only read but not edit and enter the value.

You cannot make DFF segment read-only through personalization but you can restrict users from changing the value in DFF segment through personalization by displaying error message when they try to save the form.

Steps:
1. Define New Segment for DFF in Transactions forms.
2. Define Security Rules
3. Test it.

If you are not familiar with enabling the DFF (Descriptive FlexFields) click here

So we have already one segment Available.

DFF that I have in this form is
