Material Exchange Using SAP SCM

Use

You can branch to the SAP SCM system from the ERP system to use the r ules-based availability check functions (also known as rules-based ATP check) with material exchange in the following areas:

  • Plant maintenance orders (including upgrade orders and refurbishment order consumption components)

    You can:

    • Perform the r ules-based availability check on individual components

    • Use structure nodes to check the permissibility of a material component in a PM order against a technical object list, for example, a master parts list (MPL). Depending on your Customizing settings, the structure node can be manually entered or/and the structure node can be checked or determined by the MPL.

      For more information, see Parts Interchangeability in Plant Maintenance Orders .

  • Goods movement transaction MIGO

    When posting goods receipts and goods issues in transaction MIGO , interchangeable materials can be determined in SAP SCM using the rules-based ATP logic. For more information, see Parts Interchangeability in Goods Movement Transaction MIGO .

  • Configuration Control

    You can determine interchangeable parts using SAP SCM within configuration control functions. For more information, see Parts Interchangeability with Configuration Control .

  • Subcontracting

    For rework materials of subcontracting orders. For more information, see Parts Interchangeability in Subcontracting .

Integration

  • We have integrated the SAP SCM repair or buy function in spare parts planning (SPP) with SAP ERP so that planning results from SPP can be further processed with all associated information in SAP ERP to execute repairs internally or externally. This integration provides material exchange functions in the upgrade order (for internal repairs) and subcontracting order (for external repairs).

  • SAP SCM 5.1 or higher must be connected to the ECC-DIMP system.

  • The following business functions must be activated:

    • DIMP_SDUD

    • AD_MPN_SCM

    • AD_MPN_SCM_2

Prerequisites

You must make the following settings for all the SAP SCM interchangeability functions listed above:

  • The materials must be APO-relevant and you must use the APO-ATP check (one active integration model with ATP check).

  • If you want to work with structure nodes in rules-based ATP, you must create additional fields in the field catalog in SAP SCM. You must create the following data elements to receive unique text information for the customer-specific field in the field catalog:

    • STRUC_CODE

    • STRUC_CLASS

    • STRUC_CLASSTYP

      If you want to add additional fields to the field catalog in SAP SCM containing information from the SAP ERP system, you use method ENRICH_FIELDCAT in BAdI AD_MPN_RBA_IC.

      You maintain the fields in Customizing for SAP SCM under Start of the navigation path Advanced Planning and Optimization Next navigation step Global Available-to-Promise (Global ATP) Next navigation step Product Allocation Next navigation step Maintain Field Catalog.

  • In the ERP system, you must maintain the Customizing settings for Interchangeability with SAP SCM 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 End of the navigation path and Define Requirement Profile. Note, that the requirement profile must have the same name in SAP ERP and SAP SCM.

  • In SAP SCM, you must maintain the Customizing settings for global ATP.
