the site at step 310 and the wms updates it to reflect the shipment at step 312 fig4 illustrates the enterprise level activities initiated by the site via the pull sub process of the replenishment execution process the enterprise site will pull materials as needed e g 1 4 times per day from the rsc by sending a pull signal to the rsc at step 402 a pull signal is a request for parts i e transfer order by the enterprise site to the rsc asking the rsc provider to pick the requested parts and to deliver them to the rsc warehouse management system wms which then creates the transfer order for the warehouse operators at step 404 each pull signal has a pull request number after the materials are picked and packed for delivery at step 406 a goods issued gi document is created at step 408 containing the pull request number and provided to the enterprise at step 410 giving the enterprise visibility that the requested parts are on the way once the parts are delivered to the enterprise site at step 412 they are then received by creating a goods receipt gr at step 414 to create a gr the pull request number must be reconciled in order for the materials to be debated to the enterprise wms at step 416 combining supply assessments or forecast commit processes with traditional replenishment processes i e execution of pull signals and goods issues into days of supply offers benefits to supply chain partners in the way of common visibility of demand and supply re balancing capacity optimization inventory reduction premium transportation expense reduction and minimization of inventory stock outs as described above the present invention can be embodied in the form of computer implemented processes and apparatuses for practicing.
