This activity allows you to perform a finite scheduling for the work orders. Tell me more

The “Work Order Finite Scheduling” page appears.

Matl. /  Prod. Controller

Use the drop-down list box to select the material or production controllers for which the login user has access permission. The system displays all the material or production controllers in ascending order to which the login user is mapped.

Seq. Rule Code

Use the drop-down list box to select the sequence rule codes. The system retrieves all the available sequence rule codes in ascending order along with a blank row. The sequence rule code cannot be left blank. If a particular sequence rule code is selected then you can identify the sequencing rules to be used for sorting or sequencing a set of work orders. The multiline details are retrieved using the selected sequence rule code.

Consider WIP

Select the checkbox to retrieve all the work orders, which are currently processed that are the orders in “Started” status also. If the field is unchecked, then the system retrieves all the work orders in the “Accepted”, “Firmed” or “Released” status. The system leaves the box “Unchecked” by default on launch of the page. If the quantity is reported for the activity then the system computes the activity duration for the remaining balance quantity to be processed. The system computes the duration for the balance quantity as the sum of the setup time and (the run time per piece multiplied by balance quantity) and the batch time.

Due Date From

The starting date in the range of due dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders created from within the specified range. The system displays “Blank” by default on launch of the page.

Due Date To

The ending date in the range of due dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders within the specified range. The system displays “Blank” by default on launch of the page.

Note: Work orders between “Due Date From” and “Due Date To” are displayed.

Start Date From

The starting dates in the range of start dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders created from within the specified range. The system displays “Blank” by default on launch of the page.

Start Date To

The ending date in the range of start dates based on which the work orders are retrieved. The system checks if the format is in the correct Date Format. The system retrieves all the orders within the specified range. The system displays “Blank” by default on launch of the page.

Note: Work orders between “Start Date From” and “Start Date To” are displayed.

The system checks either “Due Date” range or "Start Date" range is specified. If the both date ranges are specified, then the system displays an error message.

The system populates the multiline based on the following criteria:

Use MRP Date

Select the checkbox to start scheduling on each activity of specific resource, which is scheduled on the specified resource number on the date suggested by the "MRP". The system leaves the box “Unchecked” by default on launch of the page. If this field is checked then for scheduling each work order the system should consider the MRP suggested start date for the order. For any specific work order, if the Start By Date is specified then the system ignores the MRP suggested start date and schedules the work order not earlier than the Start By Date and considers the Start By Date as the start date for the work order no.

Scenario

The code identifying the scenario defined for scheduling based on the sequence rule codes. Mandatory. The system displays “Blank” by default on launch of the page. The specified scenario should already exist and should be valid. During the creation of the scheduling, the scenario has to be specified. If the scenario is specified, then the system retrieves all the work order details onto the multiline .

Note: You can select either “Use MRP Date “ or “ Use Base Date” option.

Use Alternate Resource

Select the checkbox to identify the alternate resource. The system checks the availability of the mentioned resource and if the same is not available it schedules for an alternate resource. The system leaves the box “Unchecked” by default on launch of the page.

Use Base Date

Select the checkbox to start scheduling on each activity, which is scheduled on the specified resource number based on the base date. The system leaves the box “Unchecked” by default on launch of the page. If this field is checked then for scheduling each work order the system should consider the Base Date specified as the start date for all the work orders available in the multiline. For any specific work order if the Start By Date is specified then the system should ignore the Base Date for the specific work order and consider Start By Date as the start date.

Base Date

The base date from which the schedule need to be generated. This date will be considered only if Use Base Date is selected. If Use MRP Date is “Checked” then this field should be left blank. If Use Base Date is “Checked” then this field cannot be left blank and can be considered as the start date of the activity. For any activity in the multiline if the “Start By Date" is specified then the specified activity should not be scheduled before the start by date. The system displays “Blank” by default on launch of the page.

Schedule Online

Select the checkbox to execute scheduling either in online or batch mode. The system leaves the box “Unchecked” by default on launch of the page.

The system ensures that at least one record is displayed in the multiline. The system schedules the first work order in the sequencing list along with its respective activities. The system sequences all the activities that belong to the selected work order in ascending order. The system selects the first available activity that belongs to the selected work order along with all available sub-activities and duration.

For the selected resource if there exist any material problem the system updates the same in resource event for input material. Once all the activities of the selected work order are scheduled the system selects the next available work order which is in the sequence and schedule all the activities belongs to it in the order and also schedules their respective sub-activities. Once all the work order and its respective activities scheduled then the system saves the data along with the scenario specified. The result is scenario specific and the system populates the multiline with revised details of work order start date / due date and other respective details and refreshes the screen with details.

The system displays the following in the “Work Order Sequence” multiline:

Work Order No.

The number identifying the work order.

Customer Name

The name of the customer.

Item Code

The code identifying the item.

Variant Code

The code or number identifying the variant of the item.

Desc.

The description in combination of item/item variant.

Order Start Date

The start date of the work order. The system sorts the work order based on the start date and sort order either in ascending or descending order.

Order Due Date

The due date of the work order. The system sorts the work order based on the due date and sort order either in ascending or descending order.

WOPP Start Date

The start date of the process plan of work order.

WOPP End Date

The end date of the process plan of work order.

Order Qty.

The work order quantity.

Status

The work order status.

Start By Date

The date on which the work orders are scheduled. If for any specific activity in the multiline if this field is specified then the system starts of the specified activity not earlier than the specified "Start By Date" and considers this date as start date for the specific activity. The system displays “Blank” by default on launch of the page.

The system displays the following in the “Work Order Sequence” multiline:

Slack

Indicates the work order lateness or earliness. The slack time is calculated as the difference between (difference between due date and base Date) and the remaining process time. The due date represents work order due date and the remaining process time depicts the process time remaining for the work order considering process time of each activity.

Critical Ratio

The ratio between the time available to process a work order and the actual processing time for the work order. The ratio is calculated considering the base date and time. The ratio represents the difference between due date and base date divided by remaining processing time or the difference between the due date and present date divided by remaining manufacturing lead-time.

  • A critical ratio of 1.0 indicates that the work order is right on schedule.

  • A critical ratio greater than 1.0 indicates that the order is ahead of schedule

  • A critical ratio smaller than 1.0 indicates that the order is behind the schedule.

If the ratio is used as one of the parameter for sorting the work order then the system computes the critical ratio for each work order as the difference between due date and base date divided by remaining processing time (in days). For remaining process time, the activities, which are reported as “Completed” for specific work order, should not be considered. The due date represents work order due date and the remaining process time depicts the process time remaining for the work order considering process time of each activity.

Total Oper

The total number of operations involved in the completion of the work order. The total number depicts the distinct operations/activities of the work order process plan.

Total Oper Time

The total operation time involved in processing the work order. The total operation time represents the sum of the individual process time. The process time for the activity includes the sum of the queue time, setup time, run time, batch time, transport time  and wait time.

Balance Oper

The number of balance operations to be left for processing the work order. The balance operations/activities depict the number of distinct activities balance to be processed. The activities with "Completed" status are not considered.

Balance Oper Time

The balance operation time involved in the processing of the work order. The processing time computed for balance activities belong to the work order.

To proceed, carry out the following
