SAP S/4HANA Cloud all version

1. Define workflow in app "Manage Workflows for Supplier Invoices", set start condition as "Account assignment category 'WBS Element' is used, Yes" for the workflow or workflow steps.
2. Create supplier invoice, add G/L account item and assign a WBS element to it.
3. Save the invoice as completed or post it with payment block.
4. Workflow is not triggered, or the workflow step is skipped.

A statistical WBS element is used in the supplier invoice. 

Statistical projects are used for statistical cost postings and project cost reporting purposes only. Statistical WBS elements cannot be settled or carry overheads. In supplier invoice workflow, only use of non statistical project and its WBS element will trigger Workflow. This is standard system behavior.

Please use non statistical project and its WBS element in the invoice so that the workflow can be triggered.
