Extends the existing detour capability by letting you define multi-level detours (detours within detours). Detours allow warehouse workers stepping through a mobile device flow to temporarily jump to another flow (for example, to fetch some related information) and then come back to continue where they left off in the original flow. This feature supports two levels of detours out of the box, but customizers can add further levels by creating code extensions on the WHSWorkUserSessionState table.
