Table Fields — the field-level definition of every table in the ABAP Dictionary: field name, position, key flag, data element, check table, ABAP datatype, length, decimals, and domain. DD03L is the single most consequential table for this mirror's purpose: every crosswalk claim this model makes about a field's name, type, length, or foreign-key target is, at bottom, a claim that should reconcile against a DD03L row in the customer's own system. This is what lets the sovereign mirror validate itself rather than trust a hand-maintained spec — the field list here is not an SAP topic, it is the mechanism of verification for every other table's field list. SAP's real DD03L carries roughly 30 fields, mostly nesting/admin/BIDI housekeeping; this definition carries the full functional field set — identity, position, key flag, data element, check table, datatype/length/decimals, domain, and reference-field linkage for currency/quantity fields — that a crosswalk or validation engine actually consumes.
