Change document header — the audit-trail record the ledger's provenance claim depends on: who changed what business object, in which transaction, and when. Every change captured by SAP's change-document service writes one CDHDR row per change session, with the field-level detail in CDPOS underneath it. SAP's real CDHDR carries all its fields; this definition carries the table complete.
