Difference Between Structure and Table in SAP ABAP Programming

In SAP ABAP programming, a structure and a table are both data types used to store multiple related fields. However, there are some key differences between the two:

1. Structure: A structure is a data type that can contain different data types (such as integers, strings, etc.) grouped together under a single name. It is similar to a record or a class in other programming languages. Structures do not have a predefined layout in memory, and the fields are stored sequentially.
2. Table: A table, on the other hand, is a data type that can contain multiple instances of a structure or a standard data type. Tables are used to store data in rows and columns format and can be accessed using key fields. Tables can have a defined structure and can be accessed using various access methods such as SELECT, INSERT, UPDATE, and DELETE.

Overall, structures are used to define the layout or structure of a single record, while tables are used to store multiple records of the same structure for easier retrieval and manipulation of data.
