# Enum SubprocessStartupParameterCopyStrategy

OptimaJet.Workflow.Core.Model.SubprocessStartupParameterCopyStrategy

Defines the strategies supported by [TransitionDefinition.SubprocessStartupParameterCopyStrategy](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/) for selecting the parent-process parameters copied to a child process instance when a subprocess starts. Parameters whose purpose is [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/) are never copied.

Namespace: [OptimaJet.Workflow.Core.Model](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/)

```csharp
public enum SubprocessStartupParameterCopyStrategy
```

## Fields

`CopyAll = 0` 

Copies every parent-process parameter whose purpose is not [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/) to the child process instance.

`IgnoreAll = 1` 

Does not copy any parent-process parameters to the child process instance.

`CopySpecified = 2` 

Copies to the child process instance only the parent-process parameters whose purpose is not [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/) and whose names are listed in [TransitionDefinition.SubprocessSpecifiedParameters](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/).

`IgnoreSpecified = 3` 

Copies to the child process instance every parent-process parameter whose purpose is not [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/), except those whose names are listed in [TransitionDefinition.SubprocessSpecifiedParameters](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/).
