Automated Queue Time Compression (tisfc1103s000)
Use this session to evenly remove the queue time from all the operations of a production order that are not yet completed. In this way, you could meet a production order's modified delivery date or start date.
Queue time compression is supported for forward planning methods as well as for backward planning methods.
After you have selected a production order to compress in the Production Planning (tisfc0110m000) session, you can adjust the following options:
- Target Start Date and Target Finish Date
- Queue Compression Method
- Targeted Compression %
- Include Operations at Critical Work Center

-
The status of the production order.
- Item
-
The item that is produced by the production order.
- Description
-
The item's description that is produced by the production order.

- Target Finish Date
-
The date that you want to complete production after the compression process.
Note: Depending on your selection in the Queue Compression Method field, you may not reach the target. - Queue Compression Method
-
The method which LN uses to evenly remove slack from the operations' queue times.
Note: The operations should not yet reported as completed. - Targeted Compression %
-
The maximum or actual value by which queue time is reduced.
If you chose the Best Fit method:
- The maximum value by which the queue time is reduced
If you chose the Targeted Percent method:
- The actual value by which the queue time is reduced
- Include Operations at Critical Work Center
-
If this check box is selected, the queue times of bottleneck work centers are compressed when you run this session.
Note: You can define a work center as critical in master planning in the Work Centers (tirou0101m000) session. - Planning Method
-
When you use this session to remove slack from queue times, LN replans the order dates using the method in this field.
Allowed values
- Forward
-
For a production order, the planning of the production order is based on a fixed start date. A delivery date is calculated from the order run time.
For a project, the network planning for the project is executed on the basis of a fixed start date. When you start the planning in the Generate Network Planning (tppss2240m000) session, LN determines the project's delivery date with a Forward planning method.
- Backward
-
For a production order, the planning of the production order is based on a fixed delivery date. A start date is calculated from the order run time.
For a project, the network planning for the project is executed on the basis of a fixed delivery date. When you start the planning in the Generate Network Planning (tppss2240m000), LN determines the project's start date with a Backward planning method.
