  • Explain the term usage typ
  • What are the different usage types in SAP Netweaver?
  • Explain different usage types in SAP Netweaver
------------------------------------------------------------------------------------

Usage types are


i)              Structuring elements for SAP software on a technical level
ii)            Determine the intended purpose of a system
iii)           Are realized by installing and configuring a collection of software 
          components
