Concepts

This case-sensitive code system `http://terminology.hl7.org/v2plusvocab/CodeSystem/responseLevel` defines the following codes:

Code | Display | Definition | versionIntroduced | Deutsch (German, de)
AL | Always | Always. All MFA segments (whether denoting errors or not) must be returned via the application-level acknowledgment message | 2.2 | Rückmeldung immer erforderlich
ER | Error/Reject conditions only | Error/Reject conditions only. Only MFA segments denoting errors must be returned via the application-level acknowledgment for this message | 2.2 | Rückmeldung bei auftretenden Fehlern
NE | Never | Never. No application-level response needed | 2.2 | Keine Rückmeldung erforderlich
SU | Success | Success. Only MFA segments denoting success must be returned via the application-level acknowledgment for this message | 2.2 | Rückmeldung bei erfolgreicher Verarbeitung
