Enter a code identifying a period to be used on a flow schedule.

Because scheduling periods are used by both flow scheduling and kanban functions, you cannot delete a scheduling period that is either:

Enter a brief description of this planning period (24 characters).

Enter a decimal greater than 0 (zero) indicating the total number of production hours in the scheduling period.

Enter the number of calendar days in this planning period. This must be greater than or equal to the value of Work Days.

Flow Schedule Maintenance uses this value in combination with the start date of the associated schedule code to determine a date range for the schedule.

Enter the number of work days in this planning period. This cannot exceed the value of Calendar Days.

The system uses this field in combination with Hours per Period to calculate the number of hours available during each day. This is a simple average; the system does not use the shop calendar or repetitive shift calendar to determine actual work days and hours. If different hours are worked on certain days in your manufacturing environment, you should set up separate periods for the differing work schedules.

Enter an alphanumeric code representing this set of schedule information. This can be up to eight characters.

Optionally enter an alphanumeric description (24 characters) of this flow schedule code. This field is for reference and displays in other programs when you reference the schedule code.

Enter the scheduling period associated with this schedule code. This value must already be defined in Planning Period Maintenance (17.13.1.1).

When you reference this schedule code in Flow Schedule Maintenance, the system uses the associated period information from Planning Period Maintenance in date calculations. It is also used to determine date displays in some reports and inquiries.

Enter the starting date for flow schedules that use this code.

This field cannot be blank. When you enter a date, the system displays the day of the week next to the field.

Flow scheduling functions throughout the system use this value to verify that schedule dates are accurate. For example, you cannot enter a due date in Flow Schedule Maintenance using this schedule code if it is earlier than this date.

If you enter Weight or Volume, you must enter a valid weight or volume unit of measure in the UM field. UM is optional if you enter Units.

The system uses this setting together with the value of UM when it performs physical and time usage calculations for flow schedules referencing this code. When a unit of measure is specified, all items on the flow schedule are converted to that UM. If Schedule Measurement is Units and UM is blank, the system uses the stocking UM of all items on the schedule and combines them, even if the values are different. For example, it would combine one of a unit defined as EA (each) with one of a unit defined as DZ (dozen) for a total of two, even though the actual physical number of items is 13.

Enter the unit of measure associated with flow schedules that reference this code.

When Schedule Measurement is Units, you can leave this field blank or specify a valid UM. When Schedule Measurement is Weight or Volume, a valid UM is required.

Valid values are:

The first three options express flow rate in terms of the production output per period of time. The other three define the rate in terms of Takt time—the rate at which parts must be manufactured to satisfy demand. See Takt Time.

Specify whether Flow Schedule Maintenance displays the Flex Fences Data frame after you complete data entry on schedules that reference this code. The system also displays a warning message if the scheduled quantity for the period is outside the flex fence parameters.

Regardless of the value of this field, the system calculates and displays flex fence information only if records have been set up for the production line in Flex Fence Maintenance (17.13.1.10). See Flex Fences.

Specify whether Flow Schedule Maintenance displays the Physical Usage frame after you complete data entry on schedules that reference this code.

Physical usage is expressed as the percentage of the maximum production rate and target production rate represented by actual production for the period.

See Checking Physical Usage in a Schedule.

Specify whether Flow Schedule Maintenance displays the Time Usage frame after you complete data entry on schedules that reference this code. When this field is Yes, the system displays time usage data for all flow rate codes associated with the site, production line, and schedule code.

Time usage is expressed as the percentage of the available hours for a given flow rate represented by the hours used in the schedule.

See Checking Time Usage in a Schedule.

Specify whether Flow Schedule Maintenance displays the Time Usage by Day frame after you complete data entry on schedules that reference this code.

Time usage by day is expressed as the percentage of the available hours for each day represented by the hours used on that day.

Enter the optimum number of units produced by this line during the schedule period when it uses this schedule code.

This cannot be greater than the value entered in Maximum.

Flow Schedule Maintenance uses these quantities to calculate physical usage.

Enter an alphanumeric code representing the site where this production line is located. This site must be defined in Site Maintenance. You must have security access to the site, and it must be in the current database.

Enter an alphanumeric code for a production line used for manufacturing flow-scheduled items.

Optionally enter an alphanumeric description of this production line. Some programs, including reports and inquiries, display this description when you enter the production line code.

Optionally enter a default schedule code for this production line. This value must be defined in Schedule Code Maintenance. See Defining Schedule Codes.

If you enter a value, it defaults to the Schedule Code field when you create a new schedule for this production line in Flow Schedule Maintenance. Otherwise, that field is blank. Additionally, when you use Production Line Item Maintenance to identify items that can be produced on a flow production line, that program gets the default unit of measure from the default schedule code.

In Flow Schedule Maintenance, flow schedule codes are used to convey basic data about a flow schedule, including such information as periods, start dates, and unit of measure data.

Optionally enter a default flow rate code for this production line. If you enter a value, it is validated against codes entered in Generalized Codes Maintenance (36.2.13) for field flcr_rate_code.

If you enter a valid value, it defaults to the Flow Rate field when you create a new schedule for this production line in Flow Schedule Maintenance. Otherwise, that field is blank.

In Flow Schedule Maintenance, flow rate codes are associated with a specific production rate on a specific production line.

Indicate whether production receipts recorded using Kanban transactions are also recorded as completions for flow scheduled orders on this production line.

No: Kanban production receipts are not recorded as flow schedule completions.

Yes: When you record a production receipt in the Kanban module with an effective date that corresponds to a flow schedule due date for the item, the system updates the Completed field on the flow scheduled order with the quantity received.

When more than one order is available to record completions, the system applies the same logic used when you receive completed quantities in Flow Schedule Receipts (17.13.7). See Application of Received Quantities.

Enter a flow schedule code to be associated with this production line. This must be defined in Schedule Code Maintenance.

When you enter a valid value, the system displays the description and rate expression defined for the code in Schedule Code Maintenance. You can then specify target and maximum production rates for this production line.

Enter the optimum number of units produced by this line during the schedule period when it uses this schedule code.

This cannot be greater than the value entered in Maximum.

When you create a schedule using this schedule code for this production line in Flow Schedule Maintenance, the system calculates physical usage relative to this value.

You can delete schedule code detail records by pressing Delete from this field.

This cannot be smaller than the value entered in Target.

When you create a schedule using this schedule code for this production line in Flow Schedule Maintenance, the system calculates physical usage relative to this value.

You can delete schedule code detail records by pressing Delete from this field.

Enter the number of an item that can be manufactured on this flow production line. This must be a valid item defined in Item Master Maintenance (1.4.1).

An item can be associated with more than one production line.

In this case, a UM conversion record must exist between the schedule UM and the item’s stocking UM. Otherwise, the system displays an error.

Indicate the relative priority the system should assign to this production line when you use Import Flow Schedules from MRP (17.13.9) to create flow scheduled orders for this item based on MRP-generated data.

Valid values are integers greater than 0 (zero). A lower value indicates a higher preference.

When determining which production line should be used to fill MRP-generated demand for a flow-scheduled item, the system looks at all production lines for the site that can produce the item. If it finds more than one, the system considers the instance with the lowest Preference value as the primary line.

A primary line must exist during data entry. If a record exists for the same item-site combination on a different production line, you can enter the same Preference value here only if a third line has a lower value so that it can be used as the primary production line. Otherwise, you cannot complete line entry without assigning a different Preference value.

Similar logic applies when you delete an item from a production line. For example, you can produce the same item on production lines 100, 200, and 300. Production line 100 has Preference for the item set to 1; for lines 200 and 300, it is set to 2. If you delete the item from production line 100, the system cannot resolve which should be the primary line for this item. In this case, a warning message displays when you delete the item from production line 100.

Enter the relative number of the period for which the system will use the specified percentage in flex fence calculations.

This period is relative to the current date. For example, when you are using weekly schedules, period 1 covers the schedule for the week immediately following this one.

To determine the period in which the schedule being maintained falls, the system:

Numbers in this field do not have to be consecutive. If there is a gap in the sequence, the system uses the value for the previous period until it reaches the next specified period. For example, if you have percentages defined only for periods 1 and 4 and you are entering a schedule for what the system calculates to be period 3, it will continue to use flex fence parameters specified for period 1 until you maintain the schedule for period 4.

Enter the percentage the system should use in comparing a production line’s resource usage for the period being maintained with a baseline period. For example, if you enter 5, the system measures whether calculated usage is within –5 or +5 percent of the baseline period’s scheduled usage.

Typically, flex fence percentages increase over time. If you enter a percentage that is less than a previous period’s value, the system displays a warning. You can disregard this message.

When you access a schedule in Flow Schedule Maintenance, the system obtains the total schedule usage from the schedule that includes today’s date. This is the baseline value used in the flex fence calculation. It then determines the period for the schedule being maintained and uses the associated percentage to calculate minimum and maximum values. If the current schedule’s resource usage is outside that range, the system displays a warning message.

Enter the flow rate code for this item. Values are validated against codes entered in Generalized Codes Maintenance for field flcr_rate_code. The system displays the description associated with the generalized code.

In Flow Schedule Maintenance, flow rate codes are associated with a specific production rate on a specific production line. When Display Time Usage Recap is Yes in Schedule Code Maintenance for the schedule code specified in the flow schedule header, the system displays time usage data for each flow rate code defined for items on the production line.

Enter the production rate represented by this flow rate code when it is used with the specified item. When Display Time Usage Recap is Yes for the schedule code on a schedule being entered in Flow Schedule Maintenance, the system displays time usage data based on this rate.
