Extension Impact Guard

EXT_CYCLIC_DEPENDENCY_DETECTEDDefault severity: BlockerCategory: GRAPH_INTEGRITY

Cyclic extension dependency

Remediation: Break the cycle: move shared fields into a separate interface CDS view (or extend the released C1 view once), let the consumers depend on it one-directionally, and transport the collection in dependency order.

EXT_DELETE_BLOCKED_ACTIVE_CONSUMERSDefault severity: CriticalCategory: DELETION_SAFETY

Deletion blocked by active consumers

Remediation: Remove or re-point every active consumer (form templates, CDS views, APIs, app variants) before deleting the object in 'Custom Fields' / 'Custom CDS Views'; delete consumers first, then the object.

EXT_TYPE_LENGTH_CHANGE_BREAKS_CONSUMERSDefault severity: CriticalCategory: CHANGE_IMPACT

Type / length change breaks consumers

Remediation: The listed consumers carry the value with a type or length the change no longer fits (type conflict or truncation). Adapt each consumer (CDS element, form field, API property) to the new type / length in the same software collection, then rerun the listed regression tests before transporting.

EXT_HIGH_BLAST_RADIUS_WARNINGDefault severity: MajorCategory: CHANGE_IMPACT

High change blast radius

Remediation: Plan regression tests for every impacted form, CDS view and API; gate the transport with a test sign-off.

EXT_MODIFICATION_BREAKING_CONSUMERSDefault severity: MajorCategory: CHANGE_IMPACT

Modification impacts downstream consumers

Remediation: Review field mappings of all downstream consumers and adapt them in the same software collection before transporting the modification.

EXT_TARGET_OBJECT_NOT_FOUNDDefault severity: MajorCategory: GRAPH_INTEGRITY

Requested extension object absent from the dependency graph

Remediation: Check the technical name of 'target_object' (case-sensitive) and re-export the extension inventory so it contains the object and all its consumers; no impact verdict was produced.

EXT_TRANSPORT_DEPENDENCY_MISSINGDefault severity: MajorCategory: TRANSPORT_COMPLETENESS

Custom dependency not transported with the object

Remediation: Add the listed custom dependency to the same software collection (or transport) as the object, or make sure its collection is imported first; otherwise the import into the target system fails activation.

EXT_TYPE_CHANGE_REQUIRES_NEW_FIELDDefault severity: MajorCategory: CHANGE_IMPACT

Published key-user field cannot change type or shrink in place

Remediation: A published key-user custom field keeps its type, and its length cannot be reduced. Create a new custom field with the target type / length, migrate the data and re-point all consumers, then retire the old field.

EXT_SAFE_TO_DELETEDefault severity: InfoCategory: DELETION_SAFETY

No active consumers in the supplied graph

Remediation: Deletion is safe with respect to the supplied inventory only; confirm the inventory is complete for the target system, then delete via Key-User Extensibility and transport the deletion.

EXT_ARCHIVE_REJECTEDDefault severity: MajorCategory: INPUT_VALIDATION

Archive rejected by ingestion safety limits

Remediation: The archive exceeded the 100:1 expansion ratio, 500 MB total size, entry-count or 2-level nesting limit, or contained path traversal / encrypted members. Upload a flat, unencrypted archive of the export files. No verdict was produced. Re-export the artifact in one of the formats accepted by Extension Impact Guard (JSON) and re-run the analysis.

EXT_INVALID_INPUTDefault severity: MajorCategory: INPUT_VALIDATION

Artifact does not match the engine input contract

Remediation: Provide the artifact type documented for this engine; unrelated or structurally invalid documents are rejected. No verdict was produced. Re-export the artifact in one of the formats accepted by Extension Impact Guard (JSON) and re-run the analysis.

EXT_PARSE_ERRORDefault severity: MajorCategory: INPUT_VALIDATION

Artifact could not be parsed

Remediation: Fix the syntax error at the reported line/column (or re-export the file unmodified from SAP). No verdict was produced. Re-export the artifact in one of the formats accepted by Extension Impact Guard (JSON) and re-run the analysis.

EXT_PAYLOAD_TOO_LARGEDefault severity: MajorCategory: INPUT_VALIDATION

Artifact exceeds the size limit

Remediation: Split the export (e.g. per package, company code or date range) so each upload stays under the service payload limit. No verdict was produced. Re-export the artifact in one of the formats accepted by Extension Impact Guard (JSON) and re-run the analysis.

EXT_INSUFFICIENT_INPUTDefault severity: InfoCategory: INPUT_VALIDATION

Required input missing

Remediation: Supply every input the engine's contract marks as required (see the engine catalog entry). No verdict was produced. Re-export the artifact in one of the formats accepted by Extension Impact Guard (JSON) and re-run the analysis.
