Warehouses: A selection is made from among the warehouses of the plant to be planned. Safety inventory level quantities and other quantity information to be transferred into the schedule window are calculated for selected warehouses.
Schedule Start Date: The start date of the schedule. Date columns to be displayed on the schedule window are generated according to this date. This date is also processed to determine Carrying Over Quantity and bill of material revisions of materials with procurement type "production" to be used in Production Orders. Approval status is not processed for the revision to be used.
Period to be Scheduled (Day-Week-Month): Columns to be displayed on the schedule window are transferred into the window by being filtered (Day / Month / Year) in accordance with the numbers entered into the related fields.
Period to be Frozen (Day): This filter is used when schedule changes are required to be avoided.
The freezing transaction is performed at the date calculated by adding the number of days entered on this field to the Schedule Start Date. When the freezing schedule is accessed by clicking on "Update" button, related days are displayed in red and any changes cannot be performed according to the Frozen Periods parameter. Frozen periods provide precision for sales orders and user demand entries.
Frozen Periods: The information that indicates whether or not changes will be allowed in frozen periods.
Distribution Parameters: This parameter contains the following options:
- From Week to Days
- From Month to Days
There are three available values for both options: To all Days, To First Day Only and To Last Day Only. The Distribution Parameters filter allows weekly and monthly demand quantities to be automatically distributed to days.
Calculation Options Validity Date: Used to specify validity date for the calculation options.
Calculation Options: The filter used to specify parameters to be processed in calculation. This filter contains six options:
- Add Consignments Received: The calculation information of consignments received for transferred and daily totals.
- Subtract Sales Orders: The calculation information of sales orders for transferred totals only.
- Add Purchase Orders: The calculation information of purchase orders for transferred and daily totals.
- Add Planned Inputs: The calculation information of planned inputs for transferred and daily totals.
- Subtract Planned Outputs: The calculation information of consignments issued for transferred and daily totals.
- Subtract Planned Demand Slips: The calculation information of planned demands for transferred and daily totals.
Sales Order Subtraction Options: The functions of this option depend on the Subtract Sales Orders parameter of the Calculation Options filter. This option has the following options:
- All Sales Orders Will Be deleted
- Only Reserved Orders
Number of Decimal Digits: Used to specify number of decimal digits if the calculation results in decimal values.
Material (Class) Type: Used to specify material types to be considered in master production scheduling.
Material (Class) Code: Used to specify materials to be considered in master production scheduling. The materials to be used are specified by making a Group or Range definition.
Material (Class) Description: Used to specify materials to be considered in master production scheduling. The materials to be used are specified by making a Group or Range definition.
Material (Class) Aux. Code: Used filter materials by aux. codes. The materials to be used are specified by making a Group or Range definition.
Material (Class) Auth. Code: Used to specify materials by auth. codes. The filter is applied by making a group or range definition.
Material (Class) Group Code: Materials to be considered in master production scheduling can also be filtered by group codes. The filter is applied by making a group or range definition.
Material (Class) Vendor Code: Used to specify materials by vendor codes. The filter is applied by making a group or range definition.
Parent Material Class Code: Materials to be considered in master production scheduling can also be filtered by parent material class codes. The filter is applied by making a group or range definition.
Variant Code: Used to specify material variants to be considered in master production scheduling. The variants to be used are specified by making a Group or Range definition.
Variant Description: Used to specify material variants to be considered in master production scheduling. The variants to be used are specified by making a Group or Range definition.
Variant Aux. Code: Used filter material variants by aux. codes. The variants to be used are specified by making a Group or Range definition.
Calculation Type: Used to specify duration calculation type. The filter line contains the following options:
- By Production Line
- By Workstation
If "By Production Line" is selected, "Quantity Related Time" and "Non Related Time" defined in the bill of materials are taken into consideration when calculating the durations. Also for operation durations, production line shifts are taken into consideration as containing all the workstations.
For example,
Production Quantity: 20
Quantity Related Time (Min) =144
Non Related Time (Min) =1440
Product Line Shift = 24 hours
Production Duration =1440+(20*144)= 3 days
3*24/24= 3 (Production will be started 3 days before.)
When the calculation type is selected " By Production Line", the resource usages are not considered.
If "By Workstation" is selected, Operation Batches, Operation Durations and Workstation Shifts entered in operation record are considered for duration calculations.
Resource Usages Will be Processed: Used to specify whether the resource usages will be processed or not in calculations. This filter line is effective when the calculation type is selected as workstation. Filter line contains "Yes" and "No" options.
If "Yes" is selected, the fullness of the workstation is considered in calculations.
The calculations are done for the resource usage in appropriate time slices and the proposals are generated according to these criteria.
Workstation Proposal: This filter is used when the calculation type is selected as "By Workstation". Filter line contains the following options:
- Priority
- Quickest Workstation
If "Priority" is selected, planning calculations are done according to the first workstation found.
If Quickest Workstation option is selected; "Max. Duration in Queue" information is considered and the calculation is done by distributing production orders according to various workstations.
