Workflow validator

ServiceNow offers several workflow validators for workflow designers to test their workflows.

This page lists all available workflow validators. See Workflow validation for information on using workflow validators and the workflow validation report to see the type of information that is returned.

Table 1. Hanging workflows and update sets

Hanging Workflows	Update Sets
Identify workflow design decisions that can result in a hanging workflow	Identify related artifacts being moved in different update sets
ValidateTransitionOut	ValidateUpdateSetDependencies
ValidateTransitionIn	ValidateUpdateSetParentDependencies
ValidateDanglingTransition	ValidateInputVarUpdateSetDependencies
ValidateSubflows
ValidateScriptForCurrentDotUpdate

Table 2. Workflow termination and external dependencies

Unexpected Workflow Termination	External Dependencies
Identify workflows that can end unexpectedly	Identify external artifacts that have potential workflow dependencies
ValidateSingleEnd	ValidateParentFlow

Table 3. Workflow conflicts

Workflow Properties Conflicts
Identify workflow design decisions that conflict with workflow properties

ValidateTableChange

• ValidateTransitionOut
  The ValidateTransitionOut validator finds activity conditions with no exit transitions.
• ValidateTransitionIn
  The ValidateTransitionIn validator finds activities that do not have inbound transitions and cannot execute in the workflow.
• ValidateDanglingTransition
  The ValidateDanglingTransition validator finds and reports any transitions that do not terminate on an activity.
• ValidateSubflows
  The ValidateSubflows validator detects any workflows included as subflows that are either inactive, deleted, or not available as a published workflow for the current user.
• ValidateScriptForCurrentDotUpdate
  The ValidateScriptForCurrentDotUpdate validator finds workflow activities with scripts that use the current.update() function.
• ValidateLowestCommonTable
  The ValidateLowestCommonTable validator reports the lowest table in the Glide hierarchy that the workflow uses.
• ValidateTableChange
  The ValidateTableChange validator reports any activities in the workflow that are invalid given the table associated with the workflow version.
• ValidateParentFlow
  The ValidateParentFlow validator reports any workflows that use the workflow as a subflow.
• ValidateSingleEnd
  The ValidateSingleEnd validator finds and identifies multiple End activities in a single workflow.
• ValidateUpdateSetDependencies
  The ValidateUpdateSetDependencies validator identifies all the subflows called in the current workflow and determines if any of those subflows are being edited in a different (in progress) update set.
• ValidateUpdateSetParentDependencies
  The ValidateUpdateSetParentDependencies validator identifies all the workflows that call the current workflow as a subflow and determines if any of those parent workflows are being edited in a different update set that is in progress.
• ValidateInputVarUpdateSetDependencies
  The ValidateInputVarUpdateSetDependencies validator examines update sets to ensure that workflow input variables for a given workflow have not been deleted in different update sets than those currently In progress.
• ValidateWorkflowEndStages
  The ValidateWorkflowEndStages validator checks that in workflows with stages, the end activity of the workflow has a stage named Complete or Completed.
• ValidateWorkflowStageColumn
  The ValidateWorkflowStageColumn validator detects and reports when the stage field (stage column) for a workflow is not correct or is unusable.
• ValidateWorkflowStateValues
  The ValidateWorkflowStateValues validator checks a number of stage aspects in workflow activities for correctness.
