The alert workflow for contracts (WS10400022) is triggered if value limits of contracts are exceeded (THRESHOLD_EXCEEDED), contracts have expired (GOING_TO_EXPIRE) or evaluations in the SAP NetWeaver Business Intelligence create the event ALERTBUSINESSWAREHOUSE. (The first two events are triggered by the contract report BBP_CONTRACT_CHECK.) These events are evaluated by SRM Alert Management. Depending on the Customizing settings (for SAP Supplier Relationship Management under  SRM Server Cross-Application Basic Settings Event and Event Schema for Alert Management Define Event Schema ) this workflow task is started or an alert or a notification message is sent. The workflow notification contains a link to the affected contract. All purchasers of a purchasing group that are assigned to the contract are potential recipients of this workflow. Activate the appropriate workflow events to use this workflow.
