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

This enhancement provides the ability to copy order lines, quote lines, and RMA lines. During Order Entry, action 3=Copy is available to copy regular lines and special lines. The new line displays in the next available line number.  This enhancement reduces manual key entry and speeds up Order Entry. 

The programs or areas impacted include ORD700D2, Order Line Entry, Quote Line Entry, and RMA Line Entry.

This enhancement prevents over-allocations and resulting overshipments to customers. Attempted over-shipments can present an error message to the user, or there is an option to automatically adjust the user’s request to the allowed quantity.

Since over-shipments result from over-allocations, Infor LX provides an optional validation during the four processes where a user can attempt to over-allocate. Note: Infor LX never over-allocates or over-ships; this always results from a user’s action. This enhancement provides three options regarding over-allocations and over-shipments:

  • Continue current process with warning message.
  • Show error message.
  • Automatically change allocation quantity to match quantity available for shipment.

If the over-ship quantity change is acceptable, internal procedures may require that the order quantity be revised so that pricing, promotions, credit checking, load planning, and other processes reflect the actual quantity.

The programs or areas impacted include:

  • ORD820D, Order Entry System Parameters
  • ORD720D2, Order Allocations
  • ORD725D, Order Entry Allocations
  • ORD570D5, Pick Confirm Inventory Confirmation
  • ORD700D2 / ORD700DA / ORD710B, Order Line Validation
