Once the condition is specified on filter lines, the Production Schedule is generated by clicking on "OK" button.
+ 
signs at the left side of the table are used to track material line calculation details.
By an appropriate fight mouse button menu the user can track a material or bill of material record.
If there is a customer order in table, the order slip can be displayed by right mouse button menu on related cell.
The calculation to determine material requirement quantity is started by Calculation 
option (or F5).
Appropriate proposal draft for the calculated quantity is presented to user in material lines.
After the calculation, the user can track the offered quantities and requirement quantities both by the window opened through Connections 
option and by arrows among table cells (by using predefined F8 transition key).
If the user wants to record table (by the existing proposal), all the required data is recorded on database and the transaction is concluded.
Points to be considered in planning are:
- Planning is performed using the main unit of each material.
- Materials to be included in Master Production Schedule, Plant and MPS Date Range are specified by the user through related filters.
- Planning can be performed as daily – weekly or daily – weekly – monthly.
- The Transferred Quantity of the first day of planning is determined according to the inventory totals before that date.
- Total order quantities for given Plants and Date Ranges are specified in main units by scanning customer orders.
- Customer demand estimations and/or internal demands can be entered on a daily, weekly or monthly basis. The distribution method of weekly and monthly entries to daily records is specified using parameters selected during the filtering operation.
- Production dates of materials without bill of material cannot be specified.
- All or a part of planned days can be frozen by the user. In this way, when MPS is run for the same period, any changes on order quantities and demand entries of frozen days are prevented.
Materials matching with conditions set on the filter lines are located on the schedule window. Details for each line can be displayed by double clicking the related line or clicking on "Display Details" button. Information and functions included within details are:
Unadjusted Procurement Quantity: The difference between net requirement quantity and Previous Procurement Quantity.
Previous Procurement Quantity: Displays Production Orders with "Work in Process" status and orders with "Deliverable" status.
Note: Unadjusted procurement quantity and previous procurement quantity lines are basis on scheduling. That is to say, a procurement transaction actualized with a schedule concerns only that schedule. However, after the procurement transaction has a warehouse transaction, it displays in the new schedule's warehouse totals.
Transferred Total = Actual Inventory + (-Consignment Issued + Consignment Return) + (Consignment Received – Consignment Return + Purchase Orders – Planned Outputs + Planned Inputs – Sales Orders)
Warehouse Totals = Actual Inventory + (-Consignment Issued + Consignment Return) + (Consignment Received – Consignment Return + Purchase Orders – Planned Outputs + Planned Inputs)
Planned Inventory Change: The quantity of planned inventory change.
Inventory Target Quantity: The target inventory quantity.
Available Quantity= Transferred Total + Warehouse Totals + Planned Inventory Change + Inventory Target Quantity
Sales Orders: Displays the sales order quantity for the day selected on the schedule.
Demand Slips Total: Displays demand slip totals.
Demand Quantity: Displays the quantity entered by the user.
Independent Requirement Quantity = Sales Orders (MIP) + Demand Slips Total + Demand Quantity
Dependent Requirement Quantity: Displays the input requirement resulting from BOM explosion.
MPS Requirement Quantity: Displays the MPS requirement quantity.
Requirement Quantity = Gross Requirement Quantity – Available Quantity
Gross Requirement Quantity = Independent Requirement Quantity + Dependent Requirement Quantity + MPS Requirement Quantity
Net Requirement Quantity: Displays the net requirement quantity.
Calculate transaction is used to specify days on which total delivery quantities and backward requirements on the schedule will be delivered. The requirement delivery method is specified using Plant Parameters of the Material. Bill of material relation definitions applied for plant and planning periods of materials for which Planning option is selected, quantity dependent/independent durations, information regarding product lines with assigned shifts, and the Lot Sizing Method defined on Plant Parameters of the material are processed in calculation.
The Delivery Time on the Material record is processed if the Procurement Type is Purchase. The production start day is specified using this information and by going backwards from days required. Daily production quantities are displayed on the line of the Planning window containing the material code. Production dates of materials without valid bill of material relations cannot be specified. Lead Time is considered as zero if not specified.
Schedule results are recorded by clicking on "Save" button. Production Planning Proposals can be generated after the related record transaction is completed.
Generating Production Planning Proposals
In the LOGO application, proposal transactions are generated using three methods:
- By clicking "OK" button located in "Do you want to realize Production planning proposals?" warning message window displayed when schedule results are recorded,
- One by one using Production Planning Proposals located on the Transactions menu of the Planning section,
- In batches by specifying the appropriate filters in the Realization of Planning Proposals menu located in the Transactions menu of the Planning section.
