Basic Components of SAP

Plethora of components is provided by the trailblazer of ERP market i.e. SAP to fulfil the needs of different consumers.
In this article I would like to give a very brief introduction to all the important SAP Components we come across while working on SAP.

ECC: It is known as “master system” in sap, comprising of all the data. It is one of the key systems in any landscape. Since this system has the maximum amount of data and other components extract data from this system it has the largest database.

BW/BWABasic usage of BW is for data warehousing i.e. for extraction of data, its analysis and reporting. BW system is connected to ECC, PI, SCM, BPC and SRM systems. BWA is BW Accelerator and is used to indexing of data, different blades are setup for this indexing of data in Abap BW systems. BWA blades configuration can be checked through TREX_ADMIN tcode in BW system.BW system consists of both Split stack and Dual stack architecture for ABAP and JAVA systems. Split stack means that ABAP and JAVA systems both are different systems having same database but different SID’s. Dual stack means that ABAP and JAVA system are a part of one system only and has same SID.

;
CRM: Basically a way to automate customer facing activities like sales, marketing and customer service. End user connects to the portal and then the portal is connected to CRM JAVA system, CRM JAVA system is connected to CRM ABAP system for data. In some landscapes TREX is also a part of this structure such that indexing of data can be achieved and in a way enhancing the performance.


PO/PI: Process Integration system is a powerful middleware provided by sap for end to end integration between SAP and Non-SAP systems. SAP PO i.e. Process Orchestration encompasses all the tools we need to create business logic, applications and integration required to plug in between our IT system and Extension profile.

SRM: Supplier relationship Management provides us a way to coordinate with the key suppliers. SRM system helps us design procurement strategy to work more effectively with our suppliers, this could help in maintaining long term relationship with them.

APO: SAP APO is Advanced Planning and Optimization is used to plan and execute supply chain processes. It provides constant optimization and evaluation of the supply chain network’s efficiency. It is connected to ECC system for master data optimization.

Portal: It is a JAVA only system and is used by end user to login to different systems. SSO i.e. Single Sign On is enabled in this to provide access to user without prompting for password using LDAP.

Solman:  This system is owned by Basis Team for performing there administration tasks. Solman system is a very basic system but it has many functionalities such as Managed system configuration (Mechanism for alerts), CCMS, EWA reports setup, Charm configuration for trasports etc. Solman system can also work as SLD (system landscape directory) system depending on the architecture of the landscape.

SLD: System Landscape Directory system contains the information of all the systems of landscape. SLD system updates the information of all the systems in a landscape on Service Market Place. SLD system is also connected to PI system for Integration related tasks.

TREX: Trex system is basically used for data table indexing. It is connected to CRM, SRM and BW system depending on the architecture of landscape for indexing.

WILY Introscope: Introscope is an application management solution created to manage Java Application performance. It allows us to monitor and manage live system performance in a production environment.

GRCGovernance, Risk and Compliance system is used for governance of all the system or components in sap. This system help in Risk Analysis and financial compliance. For achieving optimum governance we have firefighter ids which are used to access the production systems in emergency situations where administrator’s ids doesn’t have the relevant access. So a GRC environment is connected to all the system for which we require firefighter ids.


CE: As of SAP NetWeaver 7.3, SAP NetWeaver Composition Environment (CE) has become part of the overall SAP NetWeaver platform. In the overall SAP NetWeaver documentation, CE is referred to as SAP NetWeaver Composition Environment, or by its corresponding use case Building Composite Applications.

MDG: SAP Master Data Governance comprises of applications to govern master data for Line of Business Processes. Used to create, maintain, and replicate master data across domains; aligned with business processes and business rules across Lines of Business (built on ECC for native SAP Business Suite integration); replication to SAP and non-SAP systems.

Vendavo: Vendavo is the leading provider of price and margin management software to global business to companies. It’s a third party tool and used for setting the prices using B2B Power & Risk pricing methodology.

CPS: Central processing system is a third party application Redwoods which is acquired by SAP and is used for scheduling and management of background job chains.

NWDI: Netweaver Development Infrastructure is used by developers since it provides many features for increasing the productivity of developers. Features such as build scripts are created automatically based on the component type, provides a consistent pool of up-to-date libraries, support automatic deployment of built results into central test systems.

ILM: Information Life cycle management and is used to manage the lifecycle of live and archived data based on rules. It has typical features like Storage of archived data on an ILM-certified WebDAV server, Definition of ILM rules for mapping legal requirements, putting legal holds on data and destruction of data.

Sabrix: SAP does not have inbuilt Tax calculation solution, ‘Sabrix’ is one of the many external tax Software products used by SAP. As Sabrix is a SAP bolt-on, required information needs to be passed from SAP to Sabrix to calculate tax and receive the results from Sabrix back in SAP. There must be communication established between ECC SAP & SABRIX. Communication between these two is established using SAP RFC.

These are just basic SAP components which are very famous and you will come across these systems very frequently. Thanks for reading Cheers!!
