SRS (Supplier Release Scheduling), previously called VRS (Vendor Release Scheduling)


This document will provide full details of the Supplier Release Scheduling (SRS) process, including processing options, Adhoc Scheduling etc.  The screen prints below are from 9.0. 


Supplier Release Scheduling (VRS - Vendor Release Scheduling) is a supplement to MRP.  This additional functionality enhances the vendor experience and includes them as a partner to planning, by providing Vendors with an insight into future requirements 

SRS sits well in a pull supply chain scenario where the factory/warehouse/end client feeds information about its delivery and production capabilities such as Storage space, delivery dates, locations, and where the supplier pushes / feeds back information to the Buyer regarding its shipping capabilities such as container size, port shipping times/days and where a mutual agreement can be had regarding rules like releasable days (duration of contracts), guaranteed costs and spot market/harvest prices.

There are always costs involved, SRS enables both the customer and vendor a point in time in which costs incurred will be covered (raw material commitments, fabrication time (includes labor) and the time in which no changes can be made (Frozen lead time) to an agreed upon schedule.  This functionality provides suppliers the same information planners see for upcoming purchasing demands, and provides a window of opportunity for upcoming sales. The SRS system enables users to keep track of what has been shipped and what is planned to ship.  Some Examples of industries using this would commonly include those importing global food stuffs, harvested crops, Industries sourcing goods with very long lead times.  Industries with limited storage capability could use this for long lead-time large Configured project part scheduling.

MRP still plans as normal.  

SRS will process Order (O), Order & Expedite (B), & Increase Order Quantity (G) message types only.  SRS Schedules are built from MRP Messages. If an item does not have MRP Messages at the time SRS run then a Schedule will not be created for that item.  When a new item is processed if a Schedule is not created confirm that MRP Messages exist for the item.
