Processing of Inbound Deliveries 
You can use this process to create and process inbound deliveries. Inbound deliveries are entered manually on the user interface or sent from other systems using ALE infrastructure. This interaction supports the process by providing precise and reliable information at all times throughout the process. For more information on communication between different systems, see Communication and Architecture and Communication.

You can access the screen for Inbound Delivery Processing by choosingLogistics ® Logistics Execution ® Inbound Process ® Goods Receipt for Inbound Delivery ® Extended Inbound Delivery Processing ® Process Inbound Delivery or by entering the transaction code VL60.
Generally speaking, the inbound process involves the following steps:
1. Parsing, or analyzing the new or replacement ASN data from the user interface, the vendor, SAP Extended Warehouse Management (SAP EWM) or SAP Inventory Collaboration Hub (SAP ICH) by using the inbound interface
2. Validating the data and processing the inbound deliveries (IDs) based on the received data; validation errors are dispatched to SAP ICH
3. Informing SAP Advanced Planning and Optimization (SAP APO), SAP EWM and SAP ICH systems about relevant changes and updated data
4. Receiving confirmation of a goods receipt (for example, quantity difference or reversal) from SAP EWM, which triggers the goods receipt process in SPM
5. Receiving the split request from SAP EWM
