PPC ATP Planner for the availability check   



It is of paramount importance for the production process to ensure that sufficient production capacity and all necessary components are always available. This is why the availability check also plays a significant role in business software systems which offer functionalities for in-house production and external procurement planning.

The PPC ATP Planner is fully integrated into the SAP ERP standard and is based on the ATP logic of the SAP availability check. The integrated option of a capacity analysis and the consideration of multi-level dynamic order networks create a substantial added value for your supply chain planning. The transparent display of the capacity load on your resources and multi-level material availability in the same user interface makes it easier to get quick reliable statements about delivery dates. It allows to identify problems in the supply chain early, to track their causes and to simulate possible solutions.

Functional interaction of analysis and planning

Analysis of the existing situation: Availability check of material and capacity

The multi-level analysis of the demand and receipt situation indicates whether the observed demands (e.g. from sales orders) can be covered completely and in time. It also indicates whether the receipt elements find sufficient free capacity on the resources.

  • Dynamic creation of multi-level order networks
    Across all production levels demand and receipt elements are dynamically linked (in a so-called “pegging structure”; assigning receipts to demands is called “pegging”). Significant key figures allow the planner, even in anonymous make-to-stock production, to quickly identify at which points in the production process problems are likely to arise.

  • Prioritisation of certain demands
    Flexible settings permit to prioritize different demand elements, e.g. in order to cover specific customer demands first. The prioritisation can be inherited to subordinate production levels.
  • Pegged requirements display
    The multi-level upwards analysis starts from demands or receipts on a lower production level and determines which independent demands on top level are covered by them. Example: The planner would like to find out which consequences a shortness of supplies has and which sales orders are affected by it.
  • Availability check
    Based on demands or receipts on a higher production level, the multi-level downwards analysis determines if the material availability is guaranteed on all subordinate production levels. Example: The planner checks whether all components are available on time to release a production order or to deliver a sales order by the deadline.
  • Consideration of capacity bottlenecks
    In order to be able to determine a realistic customer delivery date it is essential to identify and to fix overloads early. For this purpose, the capacity load of relevant resources in the analysed order network is displayed.

  • Flexible settings for alerts
    Customisable alerts help the planner to recognise critical issues quickly. For example, alerts can be set for delayed receipts, lack of raw materials or missing pegged requirements (multi-level), as well as capacity overloads.

  • Cross-plant scenarios
    The analysis is not limited to one plant. Order networks can be created across several plants. The result is an overview of the entire supply chain.
  • Transparent and clear overview
    Results of the analysis are shown in an user interface with different views, between which you can navigate comfortably. Using various filters and layouts, the user individually adjusts the display to his needs, so that he can find important information at first glance. Links to numerous relevant SAP standard transactions complete the cockpit of the PPC ATP Planner.
  • Seamless integration in SAP ERP
    Neither interfaces must be implemented nor additional hardware has to be purchased in order to use the PPC ATP Planner. It works directly with SAP ERP objects so that no master data has to be created twice. After saving, all changes are immediately consistently effective in SAP ERP.


Planning: Assurance of material and capacity availability

Based on the results of the availability check, steps to assure availability can be undertaken: Generate new MRP-relevant receipts in case of material shortage or postpone existing receipts due to resource overloads or missing components.

  • Automatic adjustment of order networks
    Scheduling inconsistencies in multi-level order networks are resolved automatically by intelligent algorithms. For example the order network can be adapted to the late arrival of a purchase order to place planned and production orders on manageable dates, to which the components are available.
  • Simulation of new MRP-relevant receipts
    If material shortages in the order network are detected during the material availability check, new MRP-relevant receipt elements can be generated by simulation. Therefore, analysis can be continued for subordinated components. When saving, simulated receipt elements can be created automatically in SAP ERP on request.
  • Simulation of new demands and demand changes
    In order to evaluate what-if scenarios, additional demands or demand changes are simulated and the resulting effects on the material and capacity situation are observed instantly. Likewise, an analysis of SAP long-term planning scenarios is possible.

  • Determination of feasible realistic delivery dates
    A simultaneous multi-level check of material and capacity availability determines feasible and thus reliable delivery dates for customer demands, so that a high delivery reliability is achieved.
  • Update sales order
    Determined delivery dates are taken directly from the availability check and given over as confirmed dates into the sales orders.
  • Sales order integration
    The PPC ATP Planner can also be called instead of the SAP standard availability check directly from a sales order (VA01/VA02) or a delivery schedule (VA31/VA32) – without any modifications. The result of the analysis is directly taken over in the sales order.

    In sum, all functions of the PPC ATP Planner ensure that the planning accuracy in your company improves significantly and that you can meet the delivery dates promised to your customers.
