I’m Toby Schofield, from a little town called Nunhead in South East London. I have always been around IBM systems as my Dad was already working as a Contract RPG programmer for as far back as I can remember. Did a few jobs in IT including JBA then left and came to Chicago in ’94 contracting at JBA…where I was offered a job by JBA again. I started my own Company in ’99 and for the most part have continued to modify System/21.
I have a few broken bones from my misspent youth and have always been interested in Martial Arts which doesn’t actually mean I’m any good at it.
Big fan of Lizards, had a couple of Savannah Monitors, Iguanas, even little ones like Agamas.
Blogs and Videos of being silly as I find them (and check they are not too dodgy) so check in once in awhile.

3PL Scheduled Integration
April 2012 to January 2013
Storing the components required for Finished Goods assembly was a storage headache so 3PL was introduced. Vehicles on all assembly lines expected to be built on the next working day where initially scheduled based on a series of pre-determined factors (Previously scheduled, Delivery Tolerance, machine set up, Capacity etc.). Each Line had a specific Scheduler who could then fine tune the schedule. The Schedule could be sampled at any time by a process which netted off component quantities as it ran and exploded each configured BOM to determine how much of each component was on hand locally and how much would need to be supplied to the plant to avoid a hard stop. Stock was available at the 3PL remote storage facility so Local component shortfalls triggered Custom DRP orders that were sent to the remote facility via web service to ensure adequate deliveries throughout the build day. As shipments were delivered they were scanned and the DRP orders were closed out. If a component caused a negative Inventory balance despite both locations a Custom PO would be created for the Supplier and the schedule could be manipulated again to remove or replace the Finished Good(s) with the intention of reintroducing them based on Lead time if necessary.
Registration on Line
As Finished Goods Vehicles were Booked (System/21) a Custom database recorded details (Dates, Work Order, Serial, VIN, Model etc.) which became available to a Web site (ASP.NET) once the Vehicle was shipped. A Web Service retrieved these details from IBMi via BizTalk using Serial Number or VIN. This allowed the End User to confirm details such as Warranty Start/End Date or Model Year to help them track the correct Parts and Accessories. In turn, registering the Vehicle provided details such as End User Name,
Address internally that had previously been very difficult for the Manufacturer to obtain as a wholesaler.
June 2009 to February 2010
A Customer wanted to move their Parts and Accessory ordering to a web based solution. The initial responsibility was to select a technically adequate vendor then request from their web service any unprocessed shopping carts. These were returned to IBMi via BizTalk and converted into System/21 Sales Orders. As the orders were public, shopping carts were only released after credit cards were approved and a single cash customer defined in JBA was used to process these orders. The actual customer who placed the
Shopping Cart appeared on all shipping documentation.
MPS Short Term
Each Vehicle on each assembly line has a series of components also used on other Vehicles, to determine Vehicle build capacity within a week, each suggested Vehicle’s BOM was exploded to determine stock levels, labor time and lead time (where necessary), some selected options may require a sizable machine set up overhead for an otherwise generic Vehicle. The Results allowed re scheduling of Vehicles that may cause a Hard Stop on the Assembly line if attempted.
A more automated assembly line was introduced with ‘smart tools’ and overhead instructions for the builders. The instructions were stored on Custom tables within the ERP system and only the relevant instructions pertaining to the Vehicle’s configuration were displayed. Line balancing can be a very costly process as machine set up time is potentially different for each configured Vehicle so the sequence of Vehicles was prearranged in a scheduling process that was then sent to Visiprise application via BizTalk.
Vehicle Schematics in manual form had been available to dealers, it was decided these would go on line via CAD so Dealers could request replacement parts; this information is not available to the general public so each dealer had a log in, the shopping carts would be converted to JBA System/21 Sales Orders for the specific dealer as they had a line of credit. The dealer’s profile/password was stored and encrypted on IBMi as these orders had to come through a firewall.
Same Day Shipping
The generic warehousing application could pick/pack what it determined to be ready but this gave very little control over what was shipped. Each Item was given a weight and each Item/Location was given a rating (easy to difficult) and the customer was also recognized. This allowed an interactive process to determine how long pick/pack would take given the number of warehouse staff or the number of staff needed to pick/pack in a given time frame. As weight is recorded heavy orders could be held and processed later as Motor Freight. The process produced pick labels that gave the warehouse staff the most efficient route and pack labels suggested pack stations to group by customer, weight, shipping method and other relevant details to the shipment.
Richter look and Feel
System/21 Manufacturing was a good solution for supply/demand but the operation sequence was not descriptive for shop floor documentation. As a previous Richter install I manipulated the route/BOM structure to have ‘cut sequences’ entered against operations so inquiries/documents could be viewed and printed in either format without interfering with the core MRP process.
Tracking Web Site
Customers of a trucking company wanted the ability to track their shipments at several points during a day. This was achieved by developing a web site using java servlets that uploaded details from an Access db and displayed the transactions to Customers through a secure login.
System/21 Inventory and Purchasing interface to PKMS as an alternative to the standard warehousing application.
Designed and coded a utility that walks a developer through the steps required to make an RPG program communicate with JBA @ctive Modeler’s workflow engine. This utility was used to improve the speed of this procedure and the consistency of the work.
Developed a utility allowing programmers to write modifications while retaining the integrity of the standard package. Implemented modular programming techniques, assisted with reusable code while leveraging existing RPG coding skills. Skeleton code is automatically generated and the process runs out side of legacy code to minimize upgrade effort.
Designed and coded an attribute based order entry, distribution and manufacturing tracking system that works within the framework of System/21 applications. This allowed the users to keep track of and request specific characteristics of inventory as it flowed through the enterprise.
Designed and coded a Client/Server based utility (VB) that allows a user to download the components of an AutoCAD design into a System/21 route structure. The data is initially stored on the i/Series (via FTP), where it can be viewed and manipulated before adding/replacing an actual BOM.

System/21 application required more capacity than available with early AS/400’s for large enterprise. Re engineered the programs to run more efficiently. Eliminated inefficient data queues, LDA etc. from the application.
