Oracle HCM Cloud allows UI customizations via Page Composer (for page-level changes) and Transaction Design Studio (for transaction-specific rules). When conflicting changes occur—e.g., Page Composer making the location field required and Transaction Design Studio hiding it for managers—the system resolves this based on the timestamp of the last modification. The documentation states that if modifications from both tools conflict, the most recent change (based on creation or update date) takes precedence, regardless of the tool used. This ensures predictable behavior without requiring a strict hierarchy between the tools.

Option A (page error) is incorrect as the system doesn’t crash—it resolves conflicts silently. Option B (inconsistent behavior) is misleading because Oracle provides a clear resolution mechanism. Option C (TDS always overrides) and Option D (Page Composer always overrides) are incorrect because precedence isn’t tool-specific but time-based. Option E accurately reflects Oracle’s behavior: the last change applied in either tool wins, aligning with the customer’s observed UI rendering.
