In SAP S/4HANA Extended Warehouse Management (EWM) advanced production integration, the system calculates the quantity of materials to be staged for production based on several factors. The system can use the exact required quantity specified in the Production Material Request (PMR). Alternatively, it can use predefined replenishment quantities (e.g., fixed quantity, or min/max quantity) maintained in the EWM control cycle for the production supply area (PSA). Furthermore, the system can round the staging quantity up to full handling units based on the quantity defined in the active packaging specifications for the product.

B. Waves: Waves are used to group existing warehouse tasks for efficient processing and picking; they do not determine the initial quantity of material to be staged.

C. Kanbans: Kanban is a separate, distinct replenishment strategy. While it triggers material supply, its quantity logic is not a basis for calculating staging quantities in PMR-based single-order or cross-order staging.

Extended Warehouse Management (EWM)

"Quantity Calculation for Staging":

"The system can calculate the required quantity for staging based on the following data:

The required quantity in the production material request

The replenishment quantity from the control cycle

The packaging specification"

This section explicitly confirms that quantities can be based on the Production Material Request (D)

Replenishment Quantities (E)

and Packaging Specifications (A).

Extended Warehouse Management (EWM)

"Wave Management":

"You can use waves to group warehouse request items or split items to be processed together in warehouse activities."

This documentation clarifies that waves are a tool for grouping work (warehouse tasks) that has already been created

not for calculating the initial material quantity.

Extended Warehouse Management (EWM)

"Kanban":

"In Extended Warehouse Management (EWM)

you can use the Kanban processing method to stage materials for production."

The documentation describes Kanban as a self-contained process triggered by setting a container to empty

which is a different mechanism from the PMR-based staging methods referenced in the question.
