Planning Table and Sequencing

Use

If you want to schedule planned orders on the basis of production rates and takt times, use the planning table with Sequencing.

Sequencing is a production line-oriented, graphic tool that schedules the planned orders you create in the planning table or that were created in the planning run and then sequences them according to a predefined process.

As the planned orders dispatched in Sequencing are automatically firmed, you should only use Sequencing in the short-term period.

Prerequisites

In Line Design, you must create a line hierarchy for the production line.

In the line hierarchy, you must create a unit of measure for the production rate.

If this unit of measure deviates from the material’s unit of measure, you must specify the line hierarchy’s unit of measure and the conversion factor in the material master record, under Extras ® Units of measure.

You must specify the number of takts and the maximum production rate in the line hierarchy.

If necessary, you must create a rate routing in Line Design if you work with line balancing.

If necessary, you must carry out line balancing.

You must enter the line hierarchy in the production version of the material.

You must enter a repetitive manufacturing profile in the MRP data in the material master record.

You must select the indicator taktTm/rate sched. in Customizing for Repetitive Manufacturing in the activity, Define Scheduling Parameters for Planned Orders

In Sequencing, you must select the process for sequencing – that is either FIFO, manual or user exit. In so doing, the system automatically dispatches all planned orders you have assigned to a line.

Further prerequisites for working with Sequencing are described in the section Sequencing.

Features

Scheduling on the basis of a production rate.

In this case, the system uses the production rate and number of takts you entered manually to schedule the planned orders in Sequencing. The advantage here is that you do not have to maintain a rate routing. You only have to create a line hierarchy for the production line.

Scheduling on the basis of line balancing

In this case, the system uses the production rate determined in line balancing in Line Design and the number of takts for scheduling. Here, you have to maintain a line hierarchy and a rate routing and you also have to carry out line balancing.

You can access the sequence schedule from the planning table. The planned orders you assigned to a production line in the planning table or that were automatically assigned to a production line in the planning run are already dispatched in the sequence schedule and are displayed in the upper section of the screen.

In the graphic, it is easy to dispatch, deallocate and reschedule the planned orders.

You can view the results of processing immediately in the planning table and in the sequence schedule.

You can use the line-on/line-off views in the planning table and in the sequence schedule to check when the parts of an order to be produced arrive at the production line or line segment and when they leave the production line or line segment.

You can use either a quantity or time-based display for the line. You select which display you want using the totals display function. You can choose to display the time already occupied or the time still available (free) or you can display the quantities already planned or the quantities which can still be planned on the production line (quantities possible).

From the planning table, you can change the planning segment and the visualization segments displayed in the planning table and in the sequence schedule.

From the planning table, you can change the operative production rate/takt time. For the defined periods, the system then uses this production rate/takt time for scheduling.
