SAP Tables — the master registry of every table and structure in the ABAP Dictionary: its category (transparent, pooled, cluster, structure, view), delivery class, buffering behavior, and activation state. DD02L is the anchor every other DD0xL table's TABNAME field checks against, and it is the single most load-bearing table in this lane: the sovereign mirror's whole validation posture rests on being able to ask 'does this table actually exist in the customer's system, and what kind of object is it' against DD02L rather than against a crosswalk author's assumption. SAP's real DD02L carries roughly 30 fields, mostly activation/versioning housekeeping and DB-specific storage flags; this definition carries the full functional set — identity, table category, delivery class, buffering, and view/search-help linkage — that a crosswalk or validation engine actually consumes.
