 Core Interface (CIF)


The Core Interface (CIF) is the interface that enables data to be exchanged between an ERP system, in other words, SAP R/3 , SAP R/3 Enterprise, or SAP ERP Central Component ( SAP ECC ) and a connected SCM system.


To make the relevant communication layer available in the ERP system, you must import a suitable SAP R/3 Plug-In up to and including SAP ECC 5.0 . As of SAP ECC 6.0 , CIF is an integrated part of the ERP system.


CIF provides the following central functions:

  • Determine source and target systems within complex system environments

  • Initial transfer of master data from the ERP system

  • If your SCM system is SAP Advanced Planning and Optimization (SAP APO), CIF offers the following additional functions:

    • Transfer of planning-relevant transaction data and changes to transaction data

    • Return of planning results from SAP APO

  • Tools for administering the data transfer
