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

OPERATIONS:
Shelf Life Days and Retest Days
This feature provides the ability to enter information in the shelf life days and retest days fields for non-QMS lot controlled items, even when the QMS product is installed. The purpose of this enhancement is to allow the user to enter information for non-QMS lot controlled items even when QMS is activated in Parameters Generation, SYS800D.

In previous versions, when QMS was activated, the Shelf Life Days and Retest Days fields in Facility Planning Maintenance (MRP140) and Item Master Maintenance (INV100) were not maintainable for non-QMS lot controlled items.

FINANCE
Inventory Transaction Post to G/L by Cost Type
This enhancement provides a method to post material, labor, and overhead values on inventory postings to the general ledger to meet financial reporting requirements. The solution provides an optional further breakdown of cost by cost bucket using the new G/L Cost Type.

TECHNOLOGY:
Role-Based Security
Role-Based Security introduces Role type profiles and allows combining the use of Role profiles with the traditional LX User type security profile functionality. The new Role type profile can be defined to allow or deny access to All Products, Attention Key, Products, Programs, and Transaction Effects. Facility, Warehouse, and Company securities are still defined solely by the User profile settings and are not affected by the assignment of a Role. Where applicable, the Role authority is displayed alongside the User authority on the security profile maintenance screens making it easy to see where there are differences in authority between the User and the assigned Roles. 

When Users are assigned to Roles, security access in LX becomes a combination of authorities granted or denied by the Role, plus any User Exceptions. User Exceptions override authorities set by the Roles. A User can also be assigned to more than one Role.

This feature provides the ability to enter information in the shelf life days and retest days fields for non-QMS lot controlled items, even when the QMS product is installed. The purpose of this enhancement is to allow the user to enter information for non-QMS lot controlled items even when QMS is activated in Parameters Generation, SYS800D.

In previous versions, when QMS was activated, the Shelf Life Days and Retest Days fields in Facility Planning Maintenance (MRP140) and Item Master Maintenance (INV100) were not maintainable for non-QMS lot controlled items.
