Parts Interchangeability in Plant Maintenance Orders

Use

The rules-based availability check with material exchange in SAP SCM can be performed on the consumption components for:

  • Standard plant maintenance orders

  • Refurbishment orders

  • Upgrade orders

Rules-based availability check with material exchange in SAP SCM is also possible for the main component for upgrade orders.

The results of the rules-based availability check are displayed in the SAP SCM system. Here, you can accept or modify the proposals which are then adopted in the component list of the respective order, which is updated, for example, with the new results of a material exchange or location substitution.

Features

  • You can separately control the behavior of the rules-based availability check in SCM for the different types of plant maintenance orders listed above.

  • There is an enhanced advice code function for the components of a PM order. The advice code is entered in the material reservations during the submission of the results of the rules-based availability chec k if a material exchange for the components was executed. With the advice code you can prevent a further material exchange of the components.

  • Determination of installation locations (iPPE structure nodes)

    You can use structure nodes to check the permissibility of a material component in a PM order or refurbishment order against a technical object list, for example, a master parts list (MPL).

    The structure node is displayed on the Component tab page of the plant maintenance order. It is composed of three columns; s tructure code, class number and class type.

    Depending on your interchangeability-specific Customizing settings, the structure node can be manually entered and/or the structure node can be checked or determined by the MPL. This is controlled by the following Customizing flags:

    • Configuration Control relevant

      Controls if the structure node is checked or determined. This is only possible if it is a valid installation location for the material in the component record.

    • Manual Structure Node.

      Controls if the structure node is editable.

      For this check, interchangeability information maintained in SAP SCM can also be used for all materials active in APO .

      The structure node can be set or replaced using BAdIAD_MPN_RBA_IC.

Prerequisites

  • To use therules-based availability check in SAP SCM for the consumption/main components of the different PM orders, you mustset the IC Relevant indicator and enter an ATP requirement profile in Customizing under Start of the navigation path Logistics - General Next navigation step Interchangeability of Parts Next navigation step Parts Interchangeability with SCM Next navigation step Define Checking Groups for Parts Interchangeability with SAP SCM Next navigation step Plant Maintenance Order End of the navigation path or Refurbishment Order Consumption Components or Upgrade Orders .

  • You must makeCustomizing settings for maintaining master parts lists for technical structures using iPPE and define checking groups under Start of the navigation path Sales and Distribution Next navigation step Basic Functions Next navigation step Availability Check and Transfer of Requirements Next navigation step Availability Check Next navigation step Availability Check with ATP Logic or Against Planning Next navigation step Define Checking Group. End of the navigation path For more information see Determination of Installation Locations (iPPE Structure Nodes) .

  • Make Customizing settings to control which advice code is entered in the reservation for a PM order type, priority and availability check group of the material use advice code in Customizing under Start of the navigation path Defense Forces & Public Security Next navigation step Materials Management Next navigation step Advice and Status Code Next navigation step Define Advice Code for Maintenance Order. End of the navigation path To use this function you must have activatedthe business function DefenseForces&PublicSecurity (EA-DFP).

  • You must make settings for the rules-based availability check.

Constraints

  • Only the manual availability check can be used. The overall material availability check and the automatic check are not supported.

  • Rules-based availability check with material exchange in SCM is not possible for the main component of refurbishment orders.

  • When you convert planned orders into refurbishment orders ( MD04 ), consumption components are not adopted in the refurbishment/upgrade order. The main component is adopted.

  • There are special rules for MRP relevancy of the refurbishment order (controlled by the flag AUDISP). These rules are not be supported by the upgrade order (upgrade component). In the upgrade order, RBA with material exchange using SCM is only possible for components that are MRP-relevant. The component of the upgrade order that should be upgraded (main component) is always MRP-relevant. The MRP relevancy of the consumption components is controlled by order type specific customizing (transaction OIOE ).
