Determination of Priority for Inbound Deliveries 

Purpose

You deploy Extended Warehouse Management (EWM) priority points to allow an optimal unloading sequence for several trucks at transportation unit level in the yard. At the same time, EWM keeps updating the inbound delivery so long as the Status Warehouse Activities is not yet at Completed.

Process

...

       1.      SAP ERP receives an advanced shipping notification and creates an inbound delivery for it.

       2.      SAP ERP notifies SAP Advanced Planning and Optimization (SAP APO) and EWM about this.

       3.      Based on the notification, the system executes the following:

                            a.      SAP APO calculates the priority points at item level.

                            b.      EWM creates an inbound delivery request.

EWM or you activate the inbound delivery request.

EWM creates an inbound delivery from the active inbound delivery request.

The priority points in the inbound delivery are initial (initial value is nil) until SAP APO sends the results of the calculation for an update.

       4.      SAP APO communicates the calculated priority points to SAP ERP, which then communicates them further to EWM.

       5.      EWM updates the inbound delivery in relation to the priority points.

EWM saves the priority points for an inbound delivery at item level. EWM calls the Business Add-In (BAdI) /SCWM/EX_DLV_DET_LOAD to display the inbound delivery. This BAdI calculates an aggregated priority at header level.

       6.      EWM aggregates the priority points at transportation unit level using the BAdI /SCWM/EX_SR_PRIOP. You can see this on the user interface for unloading.

You can start the report /SCWM/PRIOP_UPDREQ for the recalculation of priority points from the SAP Easy Access display, under Extended Warehouse Management ® Delivery Processing ® Inbound Delivery ® Update Priority Points. Via SAP ERP, EWM triggers an asynchronous request for the recalculation of priority points in SAP APO. As with the first calculation (Step 4), SAP APO sends the result of this recalculation to EWM via SAP ERP. EWM updates the inbound delivery in relation to the priority points and aggregates the priority points at transportation unit level.

For more information, see the report documentation.

Result

SAP APO has calculated the priority points and has communicated this via SAP ERP to EWM. So long as the status Warehouse Activities is not yet at Completed, EWM has updated the inbound delivery in relation to the priority points.
