+## Gem e-conomic-ordrenummer
+
+- Gemmer `economic_draft_id` fra det eksisterende eksportflow som kladdens e-conomic-ordrenummer.
+- Audit-eventet `export_success` indeholder dermed det faktiske nummer i stedet for `null`.
+- Bevarer understøttelse af de øvrige eksisterende feltnavne i eksportsvaret.
+
+## Verifikation
+
+- Regressionstest dækker mapping fra `economic_draft_id` til e-conomic-ordrenummer.
