SAP GTS Interview Questions
What is relation between R/3 and SAP GTS ?
SAP R/3 is the former name of the enterprise resource planning software produced by SAP AG. It is an enterprise-wide information system designed to coordinate all the resources, information, and activities needed to complete business processes such as order fulfillment or billing. SAP R/3 was arranged into distinct functional modules, covering the typical functions in place in an organization. The most widely used modules were Financial s and Controlling (FICO), Human Resources (HR), Materials Management (MM), Sales & Distribution (SD), and Production Planning (PP). Each module handled specific business tasks on its own, but was linked to the others where applicable. For instance, an invoice from the billing transaction of Sales & Distribution would pass through to accounting, where it will appear in accounts receivable and cost of goods sold.
SAP typically focused on best practice methodologies for driving its software processes, but more recently expanded into vertical markets. In these situations, SAP produced specialized modules (referred to as IS or Industry Specific) geared toward a particular market segment, such as utilities or retail.
SAP based the architecture of R/3 on a three-tier client/server structure:
1. Presentation Layer (GUI)
2. Application Layer
3. Database Layer
SAP allows the IT supported processing of a multitude of tasks, occurring in a typical company or bank. SAP ERP is differing from R/3 mainly because it is based on SAP NetWeaver: core components can be implemented in ABAP and in Java and new functional areas are mostly no longer created as part of the previous ERP system, with closely interconnected constituents, but as self-contained components or even systems.
