We’re experiencing validation failures on non-conformance records when trying to close them. The system blocks closure if any required approval signature is missing from the workflow chain, even when the approver role has been reassigned.
Our approval workflow configuration requires three sequential signatures (Quality Manager → Operations Lead → Plant Manager), but we’re seeing validation errors like:
<ValidationError code="SIG_MISSING">
<message>Required signature not found for role: Operations Lead</message>
<workflowStep>2</workflowStep>
</ValidationError>
The issue occurs specifically when:
- User role assignments have changed mid-workflow
- Delegated approval authority is used
- Approval step is completed but signature enforcement flag is active
I’ve checked user role and permission mappings in the admin console, and all approvers have the correct “Sign NCR” permission. The electronic signature enforcement is enabled at the system level. Has anyone encountered similar validation blocks during record closure?
I’ve seen this exact issue in our environment. The validation engine doesn’t always recognize delegated signatures as valid when the original assignee’s role changes. Check your workflow configuration to see if the signature binding is tied to the user ID or the role itself. In our case, it was hardcoded to specific user IDs rather than role-based validation, which caused failures when personnel changed.
The root cause is how Arena QMS validates electronic signatures against workflow role assignments when delegation or role changes occur mid-process. Here’s the comprehensive solution addressing all three focus areas:
Approval Workflow Configuration:
Modify your workflow definition to use role-based signature validation instead of user-specific validation. Update the workflow XML to reference role groups rather than individual user IDs:
<approvalStep id="2">
<requiredRole>Operations_Lead_Role</requiredRole>
<signatureValidation type="role-based"/>
</approvalStep>
Electronic Signature Enforcement:
The enforcement policy needs to accommodate delegation scenarios. Navigate to Admin → Electronic Signatures → Enforcement Policies and enable “Accept Delegated Authority Signatures” for your non-conformance workflow. This allows the system to validate signatures from delegated approvers as equivalent to the original role holder.
Additionally, verify the signature binding configuration:
- Set signature scope to “Role-based” not “User-based”
- Enable “Inherit Delegated Permissions” flag
- Configure signature timestamp validation to use delegation effective dates
User Role and Permission Checks:
The validation failure occurs because the system checks both:
- Current role assignment at validation time
- Historical role assignment at signature time
To resolve this, implement a role audit trail that the validation engine can reference:
- Enable role change history logging in user management
- Configure validation rules to accept signatures if the user held the required role at signature timestamp
- Add a validation bypass for administrative role reassignments (with proper audit documentation)
For your specific error, run this validation check to identify the mismatch:
ValidationHelper.checkSignatureRoleBinding(
workflowStep, userId, signatureTimestamp
);
Implement a post-migration script to update existing in-flight records where role changes occurred. This script should re-validate signatures against the historical role assignments and update the validation status accordingly.
Finally, document this configuration change in your validation procedures and train approvers on the delegation workflow to ensure signatures are properly captured with role context metadata. This prevents future validation failures when personnel changes occur during active non-conformance investigations.
I’d also verify that the approval workflow configuration has the correct signature type mapping. Sometimes the workflow expects a digital signature object but receives an approval acknowledgment instead, which fails validation even though the approval was completed. You can check this in the workflow step properties under the signature requirements section. Make sure the signature type matches what your electronic signature enforcement policy requires.
The XML error you’re seeing suggests the workflow step validation is looking for a signature attribute that’s not being populated correctly. I’d recommend enabling debug logging on the validation engine to see exactly which signature object is failing the check. You might need to look at the workflow definition XML to see if there’s a mismatch between the role name in the workflow and the actual role assignment in the user profile. Sometimes there are trailing spaces or case sensitivity issues that cause these validation failures.
