Function documentationTransfer of Plant Hierarchy Data

 

This function enables the transfer of plant hierarchy data from SAP ERP to SAP OEE Management to create and update the plant hierarchy records in SAP OEE database tables in SAP MII. Data for KPIs, standard rates, and bottlenecks settings defined at the different nodes of plant hierarchy is also transferred along with the plant hierarchy data.

Integration

Shop floor data is reported against a node in the plant hierarchy. This enables analysis of data against a particular node in the hierarchy. Data associated with the plant hierarchy is specific to the type of node it is reported against.

You can configure the hierarchy nodes in the customizing activity Define Hierarchy Template under Start of the navigation path Production Next navigation step Overall Equipment Effectiveness End of the navigation path (see OEE Customizing Settings in SAP ERP).

The different data that can be associated with a node are used as follows:

  • Work center reference, capacity reference, standard rate, including preventive maintenance and shift breaks, or reporting production is used in the SAP MII layer to determine the node on which an order or operation is running.

  • Material and routing specific standard rates of production on a node is used in the SAP MII layer to calculate the Net Production Quantity.

  • Nodes marked as bottlenecks by default, or for a specific combination of material and routing details are used in the SAP MII layer to determine whether or not a node’s parent must be marked as down when a downtime event occurs at that node.

  • KPI targets defined for a node are used in the ERP-Shop Floor Integration framework to determine the color codes of the ANDON buttons for OEE KPIs on the shop floor UI.

  • Machine groups associated to a node are used in the SAP MII layer to report data against. Data for machine groups is used in the SAP HANA layer to analyze the machine groups.

Plant hierarchies defined in SAP ERP are available through the operator's dashboard for entering data against them.

Prerequisites

  • You have created or updated plant hierarchy master record in the Logistics module.

  • You have defined KPI targets, standard rates, bottlenecks, or machine groups for the nodes of the plant hierarchy.

  • You have set up ALE communication to create and transmit /OEE/PLANT01 IDoc (see Customizing for ALE for Communication with SAP OEE).

Activities

  • You create or update a plant hierarchy master record in SAP ERP (see Creating Plant Hierarchy).

  • You send it to ERP-Shop Floor Integration framework (see OEE IDoc Selection).

  • ERP-Shop Floor Integration framework creates or updates the record in SAP OEE database tables.
