Verify that SAM has the correct permissions assigned at all levels necessary in accordance with the documentation.
Areas to check for CRUD include:
If cross-references and changes histories are required, with buttons enabled in the IDD application, then the appropriate metadata content (XREF and HIST objects) are SECURE resources and are also configured accordingly.
Queries/Packages - Ensure that resources are made SECURE. Otherwise, an IDD application might not allow access to the entire subject area.
