Manage Workflows for Supplier Invoices
Application component: Workflow
App type: Transactional
Scope items: Procurement of Services
Description:  With this app, you can configure workflows to optimize the approval process for supplier invoices. For example, a blocked invoice must be released for payment by one or more persons responsible. The app provides several options for determining the approver, such as the approval by the cost center responsible, but you can also assign specific users. If a workflow with one or more steps is activated and the configured start conditions are fulfilled, the approval process is initiated. 
A Fiori application for managing approval workflows for supplier invoices.
Key features:   Choose the required workflow scenario. The following scenarios are available:  Workflow for Blocked Invoice   Workflow for Parked Invoice as Complete    Add a new workflow or copy an existing workflow and modify it according to your requirements. You can configure the workflow as follows:   Define properties such as a description and a validity period  In the tab Start Conditions, define start preconditions for the new workflow. These criteria must be fulfilled for the workflow to start. For example, you can define the following:  The company code of the supplier invoice Note You can only define one company code in the start conditions. If you want to have more than one company code defined in the start conditions, you can create a new workflow for each company code required.    The account assignment category that is used, for example, category Cost Center, or WBS Element   The blocking reason, for example, quantity variance and price variance.Note If an invoice is approved by one or all the recipients from their work items, it is released for payment at the header level but in the item level the indicator for blocking reason remains set. If you want to delete the blocking reason, use the app Release Blocked Invoices.   In the tab Step Sequence, add one or more workflow steps and assign recipients, step preconditions, and, if necessary, actions for the exception handling:Workflow Step Configuration  The Notifications tab is available if you maintain the corresponding email templates in the app Maintain Email Templates. In this tab, choose the workflow result and the email template and assign the recipient. After the workflow is approved or rejected, the email is sent to the recipient automatically.Note If you have defined Rework Invoice as Required Action for the exception Rejected, an email is not sent in case of rejection, because there is no workflow completion.     Activate or Deactivate a workflow Once you have activated the workflow, you can copy, deactivate or delete it, but you can no longer edit and change it.  Define the Order in which the start preconditions of existing workflows are checkedIf you have defined several workflows, the start preconditions are checked in the order you have defined. As soon as the start preconditions for a workflow are met, this workflow is used. This ensures that only one workflow in the list of your defined workflows is started, even if several workflows have matching start conditions.Ensure that a fallback workflow is activated  If you use the workflow scenario Workflow for Blocked Invoice, you can use the workflow Release blocked Invoice by Accounting Responsibles delivered by SAP as a fallback option.   If you use the workflow scenario Workflow for Parked Invoice as Complete, you can use the workflow Release Completed Invoice as a fallback option.   Recommendation We recommend to define the fallback workflow as the last one in the order. So, it is started if none of the other workflows applies. You can also configure your own workflow that is to be used as a fallback option.  Delete a workflow if it is no longer required.
