There are four different types of operators in the SAP ABAP and they are:

  • Arithmetic operators
  • Comparison operators
  • Bitwise operators
  • Character string operators

The following are some of the different types of variable in the SAP ABAP:

  • Static variables
  • References variables
  • System variables

The variables are the types of name data objects that are mainly used to store values within the allotted memory area of the program. In some of the cases, the developers can also change the name or the content of the variable with the help of the ABAP statements.

The following are the main data types in the SAP ABAP:

  • Byte field
  • Test field

  • Tables
  • Views
  • Domain
  • Data element
  • Type groups
  • Search help/match code objects
  • Look object
  • Structures
  • Table types

SAP ABAP data dictionary is mainly used to create and manage the data definition. Apart from this, the SAP ABAP dictionary also permits the central description of all the data that are used in the system without any types of redundancies.
