AMDPs provide powerful abstractions that enable ABAP developers to combine the benefits of the high-speed in-memory execution of SAP HANA with the well-established ABAP runtime and lifecycle model. Along with CDS Views, CDS Table Functions, and OPEN SQL, allow ABAP developers to renovate their existing assets and create new and innovative applications for SAP Business Suite on SAP HANA without losing the platform-independence of ABAP.
Core Data Services, or CDS, is a “semantically rich” Data Definition Language (or DDL) created by SAP. It provides an easy to understand and reusable tool that ABAP developers can utilize to execute the “code pushdown” paradigm. CDS has evolved into different variants, but the ABAP developer should chiefly be concerned with two specific ones…The lesser used option is HANA CDS, the database language that can be used to create tables, views, and structures on the HANA database itself. Views created in HANA can be consumed from the Netweaver AS using Native SQL. The second and most important variant of CDS that should concern ABAPers is the ABAP CDS. While significant differences have evolved between the two variants — for example, SAP HANA-based CDS obviously operates on SAP HANA, while ABAP-based CDS operates on most major database platforms as well as SAP HANA, and each has a different type of repository for development objects — both variants pursue the same goal: to represent central data definitions as a common basis for application development of all kinds.
Chances are that if you work with SAP ABAP, you have heard of SAP HANA by now. You’ve probably heard that it’s “the future” and a “game changer.”
Executing and interacting with the host operating system in ABAP is easy to do. SAP has created a framework for you to first configure via SM69 and then use via the delivered API SXPG_COMMAND_EXECUTE.
The SQL Trace, which is part of the Performance Trace (transaction ST05), is the most important tool to test the performance of the database. Now you as of ABAP 7.2, you execute it and other important measurements from inside the New ABAP Debugger.
Now in ABAP 7.4, you can enhance the functionality of a search help object to display possible search results and further values already while typing in a drop-down box beneath the search field. This assists the user who is searching for the desired entry. In addition, for fuzzy searches you can define an error-tolerant value in order to define the deviation of the relevant results.
With the new internal table constructs in ABAP 7.2 and ABAP 7.4 we have the ability to create ABAP code with fewer statements for the same functionality, without compromising readability of the code. New built-in functions like LINE_INDEX and LINE_EXISTS, and new constructor operators such as CORRESPONDING allow us more flexibility and extensibility when developing and maintaining our ABAP code.
With the new conditional code constructs in ABAP 7.2 and ABAP 7.4 we have the ability to create ABAP code with fewer statements for the same functionality, without compromising readability of the code. New boolean functions like XSDBOOL, and new conditional operators such as SWITCH and COND allow us more flexibility and extensibility when developing and maintaining our ABAP code.
With the new code constructs in ABAP 7.2 and ABAP 7.4 we have the ability to create ABAP code with fewer statements for the same functionality, without compromising readability of the code. METHOD CHAINING can make our code shorter, easier to read, and easier to maintain. INLINE DECLARATIONS can help us avoid TYPE MISMATCH errors. And using a CONSTRUCTOR OPERATOR can save us time by eliminating lines of code while increasing the readability of our code.
