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.

EGLi provides Infor LX Configurable Enterprise Accounting (CEA) functionality including Advanced Transaction Processing (ATP), a configurable ledger, and batch transaction processing in the IDF architecture.

EGLi is a complete replacement for CEA. Infor LX applications integrate with EGLi, and subsystem transactions generated in Infor LX are used to create journal entries in EGLi. The Infor LX integration system parameters allow you to specify whether CEA or EGLi is your primary financial product.

We recommend that you select CEA while you test the integration. The primary financial product flag and the CEA migration programs are designed to assist existing CEA clients with their implementation of EGLi. Journals are produced in both GL systems so you can verify that the data in both GL systems are the same. This integration includes migration programs that copy your existing CEA files to corresponding EGLi files. After you run the migration programs, EGLi should be configured and ready to use. If you are already running IDF via Ming.le or SiW, before you install EGLi, you will need to see the Ming.le integration guide for instructions on how to export EGLi tasks from IDF to SiW/Ming.le.

  • Control Date Lead Times – LX provides five separate Control Date Lead Time fields so you can specify additional lead time values for Shop Orders, Purchase Orders and Planned and Firm Planned orders. Each Control Lead Time Date represents additional time (days) required at each step in the process that needs more time (Quarantine, Stabilize), that is to say, when a component is due, and when it can be used. (working with an aerospace  precision bearing manufacturer, I had to account for the QA requirement that no measurements could be taken until the parts had been “soaked” (stored) in an atmospheric controlled environment (72 degrees, and controlled humidity) for 24 hours. This requirement added one full day of lead time between each machining operation) The MPS/MRP Generation program, as well as programs that Shop Order Material Allocation records use the five control date lead times to adjust component required dates to function in the same way as the BOM Offset Lead Time.
     
  • All programs that create MRP Planned Orders, MRP Firm Planned Orders, Shop Orders, and Purchase Orders call the Control Date Calculation program (MRP515B) to establish all five control dates. A Control Lead Time Date is used to adjust the component Required Dates data in the Material Requirements file (KMR), based on planned orders for a parent, and the FMA Required Dates data, based on shop order release dates for a parent.
