Sorted Table

These tables are sorted by specific non-unique keys.If these keys are used, the read from the tables are faster.

Sample Declaration:

TYPES:
BEGIN OF IT_VBRK,
VBELN LIKE VBRK-VBELN,
FKART LIKE VBRK-FKART,
END OF IT_VBRK.

DATA : IT_SORTED_VBRK TYPE SORTED TABLE OF IT_VBRK
WITH NON-UNIQUE KEY FKART.

Hashed Table

These tables are very useful for programming exits in BI.It is managed with an internal hash procedure. You can imagine a hashed table as a set, whose elements you can address using their unique key. Unlike standard and sorted tables, you cannot access hash tables using an index. All entries in the table must have a unique key which is stores in the table definition.

Sample Declaration:

TYPES:
BEGIN OF IT_VBRK,
VBELN LIKE VBRK-VBELN,
FKART LIKE VBRK-FKART,
END OF IT_VBRK.

DATA : IT_HASHED_VBRK TYPE HASHED TABLE OF IT_VBRK
WITH UNIQUE KEY VBELN.

Standard Tables

These tables are not restricted with respect to sorting or reading access with respect to keys.

Sample Declaration:

TYPES:
BEGIN OF IT_VBRK,
VBELN LIKE VBRK-VBELN,
FKART LIKE VBRK-FKART,
END OF IT_VBRK.

DATA : IT_STANDARD_VBRK TYPE STANDARD TABLE OF IT_VBRK.
