Selection Screen Variants - Part II

In my previous blog Selection Screen Variants - Part I

Variant Attributes:

Once we enter values on the screen and click on save there are various attributes that we can select. Here we will look into the details with the help of an example.

We have a selection screen with three fields namely: Material (Parameter) , Date and Plant ( Select Options).

Selection Screen Variants - Part I

What are variants?

In SAP ABAP reports have a mechanism for entering values for database selection or for performing different calculations through SELECTION SCREENS.

Selection screen provides a user an option to execute the reports or transactions as per his requirements and thus provide a range of values as an input.

Whenever there is a requirement to execute a report with the same set of input values again and again, for large selection screens entering the same values can be a tiresome and boring task. Thus SAP has provided a functionality to save these values in a set called as VARIANTS.

Creation of Selection Screen Variant in Module Pool Programming

Introduction

Selection screen variants can be stored only in Reports. This document explains on how to create Selection screen variant in a module program.

A simple tool to display product hierarchy in an ALV tree

Recently I start to study SD and I found the product hierarchy in transaction code V/76 could not be viewed in tree style and it is not so convenient to check:

General properties of ABAP Classes / Interfaces

Every day you create or change ABAP class in class builder. When you activate your change, have you noticed a series of objects with several "=" in the middle part of each?

ABAP News for Release 7.50 - ABAP Channels Reloaded

ABAP Channels (ABAP Messaging Channels AMC and ABAP Push Channels APC) were introduced with ABAP 7.40, SP02, SP05. They enable an event based bidirectional communication between ABAP application servers and with the internet. For that, a dedicated Push Channel Protocol (PCP) can be used since 7.40, SP08. Before ABAP 7.50, the communication between ABAP servers and the internet was restricted to the Web Socket Protocol (WS) and the AS ABAP acting as a stateless APC server. The following features are new with ABAP 7.50:

A tale of two SAP incidents

Summer is a strange time for SAP teams: lots of people go on holiday, projects are left to tick over, burning issues are put on hold. A time for those who remain to take it easy a while, take a look at those really intractable problems or catch up on technical innovations and pet projects with no-one to bother you. This is all fine in theory except that the business doesn't rest and production incidents still occur. This is the story of two such incidents and how SAP support helped us.

The first occurred right at the start of August, when nearly all my development team had already left: the SWN_SELSEN production job had started to abend. I groaned inwardly when I heard the news. Nothing could be more simple on the face of it than SWN_SELSEN: it simply selects workflow notifications and sends them out. There is no variant but the customising is fearsomely complicated and you needed to be a deeply experienced workflow guru (something I am not) to understand the code and the exits. This was a high-profile problem too - though the business impact was small, the program was sending PO approval notifications to all the top guys in the company, so when these stopped, important people noticed.

A kill to an ABAP CDS View?

In the first blog of this series we considered that CDS views are not just for the super cool HANA types, but can also be used to escape when marooned on planets with nothing but a lowly Oracle DB. Many of SAP's customers I suspect have only just begun to dip their toes into these scary HANA waters, and so its important to understand what of this new technology we can learn and use today (whilst still on the traditional non-HANA DB); and what must wait for a possible future HANA implementation.

In today's blog we will consider the performance of the ABAP CDS view with an Oracle DB, if we are without the HANA DB in the back end; all from the perspective of a certain double-o secret agent. In Teched I posed the question to an SAP expert, (Who shall remain nameless, less Spectre (of course we all know that SAP==Spectre ABAP Programmers) learn of his details and track him down), here I was lead to believe that even on Oracle the use of the ABAP CDS views would give major performance benefits over the equivalent SQL statement. I have to say I had my suspicions that this may have been a double agent trying to lure me, and so without further ado on returning from TECHED set out to test the ABAP CDS view tech with the help of my very own 00-agent and the necessary 00 CDS-View.
