In SAP Extended Warehouse Management (EWM), the automatic assignment of warehouse orders (WOs) to a resource is managed through queues. The system sorts the WOs within a queue to determine the processing sequence. This sorting is defined by sort rules in Customizing. The two primary criteria used for this sorting are the Latest Starting Date (LSD), which ensures time-critical orders are prioritized to meet deadlines (like planned goods issue time), and the Execution Priority, which is an explicitly assigned value to influence the processing sequence based on urgency.

B. By resource utilization: Resource utilization is a performance metric or an outcome of work assignment; it is not an attribute of a warehouse order used for sorting the order itself.

C. By mode: Mode is used to group warehouse orders (e.g., picking, putaway) and filter which types of WOs a resource can work on, but it is not the primary sorting criterion within that group.

1. SAP S/4HANA 2023 Help Portal - System-Guided Processing: "The system determines the next warehouse order for a resource to process... The system sorts the warehouse orders according to sort rules that you have defined in Customizing. For example

you can define that the system sorts the warehouse orders according to the latest starting date." (SAP Help Portal -> SAP S/4HANA 2023 -> Enterprise Business Applications -> Supply Chain -> Extended Warehouse Management (EWM) -> Resource Management -> Warehouse Order Processing by a Resource -> System-Guided Processing).

2. SAP S/4HANA 2023 Help Portal - Definition of Queues: The configuration for queues involves defining sort rules that determine the processing sequence. The documentation for this configuration area confirms that fields like Latest Start Date (LSDATE) and Highest Priority of WT in WO (TOPPRIO) are standard sort fields. (SAP Help Portal -> SAP S/4HANA 2023 -> EWM -> Customizing for Extended Warehouse Management -> Cross-Process Settings -> Resource Management -> Define Queues).

3. SAP Courseware EWM110 (S/4HANA 2023 version) - Unit 7: Resource Management: This course explains the configuration of queues and queue access sequences. It details how sort profiles are assigned to queues and how these profiles use warehouse order header fields

such as latest starting date and priority

to sequence the work for resources. (Section on "System-Guided and User-Driven Processing").
