The distribution of delivery documents from an SAP ERP system (or SAP S/4HANA) to SAP Extended Warehouse Management (EWM) is primarily controlled by the distribution mode setting. The standard and most common method is Immediate distribution at document creation, where the delivery is sent to EWM via queued Remote Function Call (qRFC) as soon as it is saved in the ERP system.

Additionally, Manual distribution methods can be used. This applies to scenarios where automatic distribution failed due to an error or was intentionally prevented. A user can manually trigger the distribution by re-saving the delivery document, using monitoring transactions (like the Outbound Delivery Monitor) to initiate distribution, or reprocessing a failed qRFC message in the queue monitor (transaction SMQ1).

A. Core Interface (CIF) distribution mode: The Core Interface (CIF) is used for the replication of master data (e.g., materials, customers, vendors) between ERP and EWM, not for transactional data like delivery documents.

C. Distribution via Post Processing Framework (PPF) actions: The Post Processing Framework (PPF) is a tool within the EWM system used to trigger subsequent activities (e.g., printing, warehouse task creation) after a document has been received and processed in EWM. It is not used for the initial replication from ERP.

"Communication from ERP to EWM": This document outlines the primary methods for delivery distribution. It states

"You can distribute deliveries to EWM either immediately after creating them

or you can collect them and distribute them in a background job." This directly supports "Immediate distribution". The manual reprocessing of failed queues is a standard operational procedure for this interface. (Accessed under SAP S/4HANA -> Extended Warehouse Management -> Goods Receipt and Shipping -> Communication from ERP to EWM).

2. SAP Customizing Implementation Guide (IMG): The configuration path Logistics Execution -> Extended Warehouse Management Integration -> Basic Setup of Connectivity -> Configure SAP EWM-Specific Parameters allows setting the "Distribution Mode". The options are 'Immediate Distribution' and 'Distribution as background job'. This confirms immediate distribution as a standard configurable method. Manual intervention is the standard procedure for handling exceptions to these automatic modes.

3. SAP Course EWM100 - "Processes in SAP Extended Warehouse Management": Unit on "ERP and EWM Integration". The course materials detail the qRFC technology used for delivery replication and the use of the qRFC monitor (SMQ1/SMQ2) for error handling

which involves manual actions to reprocess messages. This supports the concept of a manual distribution method in an operational context.
