Restrict fields in Change Request depending on user status / role

Hello everybody,

based on my requirements I am trying to restrict some fields in my ZMCR-Transaction from edits depending on the user status:

• After approval the field "Description" should be blocked for changes.
• The same should apply for the "Description of Change".

I already searched in SPRO "Adjust UI objects by User Status" but didn't find entries for this fields.

My second question concerns the "Approval" block. With current settings the person who requests the change can also approve it.

This activity should only assigned to the person which is linked under "Partner Function" (in this case Change Manager) or maybe above "Partner ID".

Thanks a lot,

Martin
