Our compliance audit traceability reports are failing to include requirements that are definitely linked to test cases in ELM 7.0.2. When we generate the standard traceability matrix, about 30% of requirement links appear missing even though we can see them in the test case details view.
Report template configuration seems standard:
<traceability-fields>
<requirement-link type="validates"/>
<test-case-link type="verified-by"/>
</traceability-fields>
We’ve verified that users running the reports have proper read permissions on both requirements and test cases. The data warehouse synchronization runs nightly, but the gaps persist even 48 hours after linking requirements. Traceability field mapping appears correct in the admin console. This is creating serious compliance audit trail issues as auditors question our testing coverage. Any ideas on what could cause partial traceability data in reports?
Problem solved after systematic investigation of all suggested areas. The root cause was actually a combination of three issues:
Permission Validation: The data warehouse service account had read permissions on test projects but was missing explicit read access to two legacy requirement projects that were migrated from an older system. This caused 25% of the gaps. We granted cross-project read permissions to the service account.
Traceability Field Mapping: Our test cases were using mixed link types - some used ‘validates’ while others used ‘tests’ and ‘verifies’ (custom types from our old tool). The report template only included ‘validates’. We updated the template:
<traceability-fields>
<requirement-link type="validates,tests,verifies"/>
<test-case-link type="verified-by,tested-by"/>
</traceability-fields>
Data Warehouse Synchronization: The nightly sync was completing but with warnings that weren’t visible in the standard logs. We enabled detailed sync logging and discovered that links created within 2 hours of the sync start time were being skipped due to a transaction isolation issue. We moved the sync to run at 2 AM instead of midnight and reduced the isolation level.
Report Template Configuration: Added explicit baseline scope to ensure cross-stream traceability:
<scope baseline="current" include-streams="all"/>
After implementing all fixes, we ran a full data warehouse resync and regenerated reports. Traceability gaps dropped from 30% to under 2% (remaining gaps are legitimate - test cases not yet linked). Compliance audit trail is now complete and auditors have accepted our traceability evidence. The key lesson: traceability issues rarely have a single cause - you need to validate permissions, field mappings, sync timing, and report scope together.
Data warehouse synchronization running nightly might be the bottleneck. If requirements are linked during the day but the sync hasn’t captured those changes, they won’t appear in reports until the next sync completes. Try triggering a manual data warehouse sync and then regenerating the report to see if the gaps close. Also verify that the sync job is completing successfully without errors - check the sync logs for any skipped records or permission failures during the extract phase.
The 30% gap suggests a systematic issue rather than random data corruption. First check if the missing requirements share common characteristics - are they in specific projects, created by certain users, or using particular requirement types? This pattern analysis often reveals permission or configuration boundaries causing the gaps.
Permission validation during data warehouse sync is stricter than UI permissions. Even if users can view requirements and test cases in the interface, the sync process runs under a service account that might lack cross-project read permissions. This commonly causes partial data extraction where some requirements are synchronized while others are skipped. Verify that your data warehouse service account has read access to all requirement projects, not just the test management areas.
