Summary :
When accessing WD ABAP context nodes or attributes either through custom code or UI elements, short dumps may occur due to invalid accesses or unavailability of context nodes. Causes include empty higher-level nodes, invalidated nodes due to external context mapping, singleton access without lead selection, and invalidated nodes during ALV operations. Incorrect initialization or deletion of lead selection and empty or invalidated nodes also contribute to access issues. Resolving these requires validation with IS_ALIVE(), use of ST22 for dumps, debugging, checking context paths, and utilizing a watchdog for dynamic context checks.
