CIF OverviewCIF Overview
Core interface (CIF) is the central interface that connects SAP SCM to the existing SAP ECC system environment. Data transfer between the ECC and SCM systems is defined and controlled using the Core Interface (CIF).
CIF is an integrated part of the ERP system (in SAP ECC 6.0) and also is an integrated part of SAP APO, 5.0.
![Page 6: Systems Integration EGN 5623 Enterprise Systems Optimization (Professional MSEM) Fall, 2012](https://reader036.vdocuments.site/reader036/viewer/2022062408/56813d60550346895da73161/html5/thumbnails/6.jpg)
CIF OverviewCIF Overview
CIF enables transferring master data from SAP ERP to SAP APO in one way only, and transferring transactional data in both ways between ERP and APO
In the Core Interface, the user selects the objects to be transferred to SCM via the “integration models.”
Only the planning-required parameters are transferred from the SAP ECC dataset to SAP SCM.
Technically, the transfer is performed via the queued remote function calls (qRFC).

APO Core InterfaceAPO Core Interface• Data transfer between the ECC and SCM systems is
defined and controlled using the APO Core Interface (CIF).
• CIF is the central interface that connects SAP SCM to the existing SAP ECC system environment. It is available to the ECC systems through a plug-in.
• In the APO Core Interface you select the objects that you want to transfer to SCM via “integration models.”
![Page 9: Systems Integration EGN 5623 Enterprise Systems Optimization (Professional MSEM) Fall, 2012](https://reader036.vdocuments.site/reader036/viewer/2022062408/56813d60550346895da73161/html5/thumbnails/9.jpg)
APO Core InterfaceAPO Core InterfaceOnly the planning-relevant parameters from the dataset of SAP ECC are transferred to SAP SCM. The APO Core Interface is used for both initial data transfer (initial transfer) and change transfer (transfer of data changes) to SCM.

CIF ConfigurationCIF Configuration
The communication between ERP and APO systems is based on queued remote function calls (qRFC).
To enable this communication, the user needs to configure the “Application Link Enabling” (ALE)
settings and the parameters for communication (see Figure 25.1)
define the logical systems for both ERP and APO systems

CIF ConfigurationCIF Configuration
In the ERP system, the APO logical system has to be defined as the target system by assigning the system type and release with transaction code NDV2 and the queue type with the transaction code CFC1.
The remote function calls (RFC) destination defines the address of the target system and the access data (user for the target system, password).
The RFC destination has to have the same name as the logical system of the target system and that the name is case sensitive.

Integration Models for Data TransferIntegration Models for Data Transfer• The integration model is used to specify selection criteria
for master data objects and the logical name of the target (APO) system.
• The same integration model can be used to transfer more than one type of object but it is a good practice to use multiple integration models (one per object type) to avoid complex maintenance of the selection criteria.
• When ERP sends orders to APO, the integration models check whether the active integration model exists.
• Integration models are created (T-code CFM1) and activated (T-code CFM2) on the ERP side.

Table 25.2 lists some of objects that can be included into integration models and transferred to APO.

Objects of Integration ModelsObjects of Integration ModelsWhile creating the integration model, the objects which match the selection criteria, are read in and assigned to the model.
The integration model is unique in its name, the target system, the application, and its version. The user can freely name the integration model and denotes its application. The target system is selected from the APO system that is defined in the CIF configuration.
![Page 22: Systems Integration EGN 5623 Enterprise Systems Optimization (Professional MSEM) Fall, 2012](https://reader036.vdocuments.site/reader036/viewer/2022062408/56813d60550346895da73161/html5/thumbnails/22.jpg)
Objects of Integration Model Objects of Integration Model A new version is generated for the integration model, each time when the user modifies it. The user and the date of generation are part of the version name.
The transfer of objects is sequence-dependent. For example, plants must be transferred prior to the transfer of work center.
The transfer of data is triggered by activating the model with the transaction code, CFM2.
![Page 23: Systems Integration EGN 5623 Enterprise Systems Optimization (Professional MSEM) Fall, 2012](https://reader036.vdocuments.site/reader036/viewer/2022062408/56813d60550346895da73161/html5/thumbnails/23.jpg)
Initial and Delta TransferInitial and Delta Transfer
Initial transferDuring the initial transfer, CIF (the currently active version) transfers all objects to APO.
Delta transferIf the new version is activated (while the older ones still remain active), CIF transfers only new objects (i.e., the objects that are not included in the old version).
Usually a periodical delta transfer is used for data integration, to reduce the system load.

Master Data IntegrationMaster Data IntegrationMaster data is usually one of the most crucial factors for the success of an implementation.
•Master data in ERP have to have a sufficient quality.•Master data must be kept consistent between ERP and APO, otherwise planning will be inaccurate and lead to wrong results.
•Generally strongly recommend to maintain master data in ERP environment.
![Page 26: Systems Integration EGN 5623 Enterprise Systems Optimization (Professional MSEM) Fall, 2012](https://reader036.vdocuments.site/reader036/viewer/2022062408/56813d60550346895da73161/html5/thumbnails/26.jpg)
Master Data IntegrationMaster Data IntegrationThe master data objects in SAP SCM are not identical to those in SAP ERP.
During master data transfer, the relevant SAP ERP master data is mapped to the corresponding SAP SCM master data. The SAP ERP system is the owner of most of the master data. Only specific SCM master data (such as transport lanes) that does not exist in SAP ERP is maintained in SAP SCM.

Transactional Data IntegrationTransactional Data IntegrationThe transfer of transactional data is working two ways, from ERP to APO and from APO to ERP.
From ERP to APO, there is usually one initial upload and from then onward a continuous online transfer of data changes.
From APO to ERP, the default setting for the transfer is “immediately’ for PP/DS order and “periodically” for SNP orders.
