Priorities

Priorities are used when planning on the basis of finite capacity. You determine the planning sequence by specifying a priority.

You should first register priorities on the Priorities form, and then assign them to a customer or a sales order, for example.

When scheduling operations using the Perform lead time planning process, you then select the priorities you have set in different locations. You can assign the following priorities:

  • Customer priority:

Production files are scheduled based on the priorities you have assigned to customers on the Customers form (in the Customers module).
  • Sales priority:

Production files are scheduled based on the priorities you have assigned to sales orders on the Specification tab of the Sales orders form (in the Sales module).
  • Shipping date:

The shipping date in the sales line (Sales module, Sales orders form, Lines button) for which the production file will be used, determines how the production files are scheduled.
  • Sales line status:

The status in the sales line (Sales module, Sales orders form, Lines button) for which the production file will be used, determines how the production files are scheduled.
  • Production end date:

Production files are scheduled based on their end date (production modules, Production files form, Planning tab).
  • Production priority:

Production files are scheduled based on the priority set in the production file (production modules, Production files form, Planning tab).
  • Production status:

Production files are scheduled based on the status set in the production file (production modules, Production files form, General tab).

Choosing ascending or descending priorities

For every priority, you can set an ascending or descending sorting order.

Priority 1

Specifying multiple priorities

It is possible to specify multiple priorities, in order to achieve a sort within a sort. If the priorities specified do not result in an unambiguous order, scheduling will take place based on ascending production file codes, or, in other words, based on the scheduling principle First Come, First Served (FCFS).

Example 1

  1. Customer priority, ascending
  2. Shipping date in sales line, ascending
  3. Production file status, descending

All production files with customer priority 1 are planned in order of the shipping dates specified in the sales lines for which the production file will be used. Where production files have the same customer priority and shipping date, the production file with the highest status will be scheduled first, followed by the production file with the next highest status. Production files without customer priority will be scheduled last, based on the shipping date specified in the sales line.

Example 2

  1. Production file priority, ascending
  2. Shipping date in sales line, ascending

All production files with production priority 1 are planned in order of the shipping dates specified in the sales lines for which the production file will be used. Production files without production file priority will be scheduled last, based on the shipping date specified in the sales line. You can assign the following priorities:

  • Customer priority:

Production files are scheduled based on the priorities you have assigned to customers on the Customers form (in the Customers module).
  • Sales priority:

Production files are scheduled based on the priorities you have assigned to sales orders on the Specification tab of the Sales orders form (in the Sales module).
  • Shipping date:

The shipping date in the sales line (Sales module, Sales orders form, Lines button) for which the production file will be used, determines how the production files are scheduled.
  • Sales line status:

The status in the sales line (Sales module, Sales orders form, Lines button) for which the production file will be used, determines how the production files are scheduled.
  • Production end date:

Production files are scheduled based on their end date (production modules, Production files form, Planning tab).
  • Production priority:

Production files are scheduled based on the priority set in the production file (production modules, Production files form, Planning tab).
  • Production status:

Production files are scheduled based on the status set in the production file (production modules, Production files form, General tab).
