Intercompany direct delivery is created with automatic purchase invoice validation.

If workflow is activated on Intercompany purchase company, the Intercompany sales is cannot be posted as ICO purchase invoice is not submitted to workflow.

But purchase invoice workflow cannot be submitted as set for automatic posting.

Workflow should consider Intercompany flow with automatic posting.

Workaround: conditional activation should be added to not consider intercompany.

To work workflow should not be set "as default"
