Multiple Output Planning

Purpose

Multiple Output Planning (MOP) is an enhancement to order generation in the area of Production Planning and Detailed Scheduling (PP/DS) . It makes it possible to plan production in which one product is split (by cutting or slitting, for example) into several other products.

Example Example

In your foil production, foil rolls with dimensions 3 m x 10,000 m (‘ jumbo rolls ’) are cut to 3 m x 500 m winding rolls.

End of the example.

Compared to the standard function in Production Planning and Detailed Scheduling (PP/DS) , Multiple Output Planning offers the following advantages:

  • Optimized selection of the production receipts that are to cover the order requirement

  • Offcut Determination

  • Valuated characteristics of additional receipts

Implementation Considerations

To be able to use Multiple Output Planning , you require the following systems:

  • SAP R/3 System Release 4.7 or later, Industry Business Solution SAP Mill Products Release DIMP 4.71 and at least plug-in Pl 2004.1

  • SAP APO System Release SAP SCM 4.1 or later

  • MOP heuristic /SAPAPO/EOG_HEU_PLAN_MOP

Integration

You can use Multiple Output Planning for order generation in Production Planning and Detailed Scheduling (PP/DS) . If you start Production Planning and Detailed Scheduling (PP/DS) directly from the ATP check, you can also use Multiple Output Planning within the ATP check.

Background documentation 

To do this, choose Start of the navigation path General Settings Next navigation step Maintain Check Instructions End of the navigation path in Customizing for the Global Available-to-Promise (Global ATP Check ) and then choose the setting Production first for Start product.

Features

You can use Multiple Output Planning to generate orders with a special structure. You may need to do this when planning production in which the splitting up of one product produces another product.

A Multiple Output Planning order (MOP order) can contain one operation – for dividing up one product – and one for dividing up the relevant requirement, as only the characteristics of a receipt can be propagated in the direction of manufacture (see Bottom-Up Characteristic Propagation ). If offcuts are also created when the initial product is split to create the required product, an MOP order will generally have more than one receipt node. In the production order in the SAP R/3 System, the offcuts are represented as co-products with negative quantities.

Multiple Output Planning comprises the following individual functions:

  • Receipt Search in Multiple Output Planning

    Using the receipt search in Multiple Output Planning , the system determines product receipts that have characteristic value assignments that make them suitable for the manufacture of the required product.

  • Requirement/Receipt Comparison

    The system – taking account of the required criteria defined by customer-specific logic – uses the requirements/receipts comparison to look for receipts that could cover the valuated requirement. It uses an iterative procedure to compare the receipts it found with the requirement, and uses the characteristics of the requirement and receipts to asses whether a receipt is suitable for covering the requirement.

    Note Note

    You can use the /SAPAPO/EOGM_HEUR heuristic to manually create an MOP order and to select the requirements to be covered and the product receipts to be used.

    End of the note.

  • Bottom-Up Characteristics Propagation

    With Bottom-Up Characteristic Propagation, the SAP APO System passes on characteristics value assignments of the requirement to the receipts. This type of characteristic propagation makes it possible to calculate the offcuts that may result, for example.

  • Offcut Determination

    With this function, the SAP APO System uses the relevant characteristic value assignments in production to determine offcuts.

Constraints

Multiple Output Planning has the following constraints:

  • You cannot make any manual quantity changes to output nodes or input nodes. It is not possible to insert a node. You cannot change the number and type of activities, or the requirement and receipt nodes manually.

  • In an MOP order, only one product can be divided up, as Bottom-Up Characteristic Propagation can only propagate the characteristics of one receipt in the direction of manufacture.

  • It is not possible to have operations running in parallel in an MOP order.

  • Once a material has been assigned in batch determination in the SAP R/3 System, the order is not automatically revised in the SAP APO System.

  • You can only change dates manually in the planning board, not in the product view.
