ABAP News for Release 7.40 - Table Expressions

Table expressions with the syntax

... itab[ ... ] ...

are a new way for accessing table lines in operand positions. You can view a table expression simply as a short form of a READ TABLE statement. The result of a table expression is a single table line. All you have to know is the syntax that does the same as a given READ TABLE statement.

If a table line is not found, the exception CX_SY_ITAB_LINE_NOT_FOUND is raised. No sy-subrc from expressions, of course.

Introduction to ABAP Channels

Overview

ABAP Channels infrastructure was delivered with SAP NetWeaver AS ABAP 7.40 support package 2 (SP2) for simple tests and prototyping and released with 7.40 support package 5 (SP5).

The basic idea of the ABAP Channels (see Figure 1) is the native support of interactive and collaborative scenarios based on event-driven architecture. The scope of ABAP Channels consists of the following communication channels:

• ABAP Push Channel for bi-directional communication with user agents via WebSockets in ABAP. In the Figure 1 the documents tagged with letter "P" mark the ABAP Push Channel communication paths.
• Publish/subscribe infrastructure for exchange of messages between either user sessions (Session C => Session A) or user session and user agents
