Dear SAP pros:
Author has been leading the Master Data maintenance and distribution for several years.  Master Data is so much integrated with other components that accuracy and sync of MD are very critical for successful SAP Implementations.

Please see Process Diagram presented here, and I hope this will give you a simple and clear understandings for SAP professionals.



Processes:
1.      ERP to SCM, EWM

CIF (Core Interface) distributes major Master Data objects such as Materials, Plant, Customers (location Master in SCM), Vendors (location Master in SCM), Scheduling Agreement (External Procurement Relationship), MRP areas.  Depending on the situation of company, CIF can run in either Batch mode or Immediate mode.  Multiple CIF jobs can be set up to send to many destinations as described in diagram.  Generation of CIF (CFM1 for instance) and Activation of CIF (CFM2) are major steps in CIF processing.


2.      ERP to CRM

Materials are distributed from ERP to CRM via BDOC. 


3.      CRM to ERP, SCM, EWM
