Extract SID differs from the refreshed target SID
- Default severity

- Finding code:
- REFRESH_INPUT_SID_MISMATCH
- Engine version:
- 2.1.0
What this finding means
System Refresh Delta Guard reports this finding with the default severity “Blocker”.
About the engine: Post-refresh BDLS, RFC destination, & logical system change validator
How to fix it
Re-extract from the refreshed (target) system; checks against the wrong system are meaningless.
How ERP Preflight detects it
The analysis is deterministic: the same exported files and the same knowledge snapshot always produce the same findings. No SAP system connection is required — you upload exports.

- Accepted formats
- JSON, CSV, TEXT
- What to export
Post-refresh extracts of the target system: JSON {'sid', 'client', 'rfc_destinations', 'scot', 'logical_systems', 'jobs', 'printers', 'endpoints', 'integration_destinations', 'queues', 'custom_config', 'isolation_policy'} - optionally as {'pre_refresh': {...}, 'post_refresh': {...}, 'ignore_policy': [{section, key, reason}]} for the before / after comparison - or a sectioned CSV export.
- Required input
- target SID
- RFC / SCOT / logical system / job / printer sections for a full verdict
- Evidence
- Each finding points to the artifact path, line and column, the code snippet and the SHA-256 of the uploaded file. Findings without such a pointer are demoted to confidence UNKNOWN.
- Confidence
- The verdict rests on your artifacts only. Each finding carries a confidence class (VERIFIED, RULE_DERIVED, INFERRED or UNKNOWN) that shows how strong the evidence is.
- Target releases of the engine
- S4H_2022, S4H_2023, S4HANA_CLOUD_2402, S4HANA_CLOUD_2408
