Where in the OMM's Scope of Activity can I enter Specific Approvals (SPA)?

In chapter "1.4 Scope of Activity", you'll find that 1.4.1 CAT, 1.4.2 SPO and 1.4.7 NCC each have a sub-chapters for Specific Approvals. You can "Customize" those individually and delete or modify the table rows according to your needs.
