Infor LX & BPCS Manufacturing Tip of the Week: Backward Scheduling

Operations are automatically backward scheduled at shop order release time. The backward scheduling algorithm starts with the shop order due date and schedules each operation based upon the standard move and queue times in the routings and the number of days the job is expected to run at standard. The system calculates and stores the operation scheduled start date. The dates may be modified by the shop order maintenance program. The number of days that a job is expected to run an operation is dependent upon the available capacity for that work center and the total hours scheduled for that operation.

The backward scheduling algorithm also considers the shop calendar for weekends, shutdowns, holidays, and partial days.

Backward Scheduling Process

The algorithm starts with the due date of the shop order or planned order. The system makes the following calculations for each operation in the reverse sequence:

  1. The number of move days is subtracted from the due date (or initial date of the previous operation) to get the due date for this operation. The move days are only used on valid shop calendar days.
  2. The system uses the following calculation for the number of clock hours for the operation: Standard run or machine hrs/No. of operators + setup hours
  3. The number of clock hours is spread over the available daily capacity of the work center for those given days. The system uses the following calculation for the daily capacity of the work center: Number of shifts x hours per shift x average efficiency/100
  4. Each day is checked against the shop calendar; the calculation bypasses inactive days or adjusts for any changes in the work center capacity for that day.
  5. Queue time days are subtracted in the same manner as move time days. The resulting date is the operation start date.

The algorithm then goes to the previous operation. When all operations have been included, the resulting date is the scheduled start date of the shop order. Note that MRP uses the item lead time to determine material requirement dates on planned orders.

Tips:  LX | BPCS | M3

Finance: Cost Rollup by Effective Date
Allow the load standard cost from routing and cost rollup programs to process as of a specified effective date.  With the addition of an optional effective date parameter to prompt screens for cost rollup CST500 and load standards from routing CST600. If entered, only consider bill of material components and routing operations with effective and discontinue dates that make them effective as of the entered parameter effective date.


Operations: Outside Operation Purchase Order Include Vendor Item Number
Copy the vendor item number from the vendor quote to purchase orders created automatically from outside operations of shop orders. During the process of automatically creating purchase orders from outside operations of shop orders, copy the vendor item number from the vendor quote to the purchase order line. With this change, looking at a purchase order that was created automatically for an outside operation of a shop order, the vendor item number from the vendor quote will be visible on the purchase order line.


Technology: Group Security for ILM501 Inbound Delivery Maintenance
Add function key / action code security to control who is authorized to create/revise/delete functions in ILM501 Inbound Delivery Maintenance.  With added Group Security, managers can control which users are authorized to create, change and delete deliveries in ILM501 Inbound Delivery Maintenance.
