Happy New year SCN and Happy New Excel with abap2xlsx
01 month ago
Dear community, it was in the far July 2011 that I gave you updates on the abap2xlsx project with the reporting of my adventures at SAP Inside Track in Chicago (blog). In the last weeks, I had the idea to write a blog and few days ago a great present by SAP Mentor Gregor Wolf to the project (I will give you more detail below, keep reading) gave me the final sprint to be there on time for the New Year celebration.
Abap2xlsx is still the most popular project on Code Exchange with more than 3,500 downloads and close to 300 members. There is a great interest for this project, discussion board on Code Exchange is very hot, many people are asking and helping and many members are contributing (thanks you all) to improve this project adding new features and fixing some bugs ( yes, we had some 
).
Dropdown by key or Dropdown by index, that is the question of a WDA developer
03 months ago
Introduction
During my experience as a Web Dynpro for ABAP developer, I often had the doubt if it was better to use the UI element DropDownByKey or its brother DropDownByIndex.
In these last days, I realized that I always prefer and use the DropDownByKey, it doesn’t matter if the list is inside a table, an ALV table or a simple element in a view.
Clearly the index approach is also working well but I feel it as a more complex task that requires spending more time, and I’m wondering to know about your experience.
As a reference, I’m sharing below the step-by-step guide to build a DDL even without necessarily entering the fixed values associated to a domain of the field.

Ladies and Gentleman did you ever thought to use you old ABAP system to use modern cloud services?
Last year SAP Mentor Uwe Fetzer (@se38) published his Twibap, a simple Twitter API to use in order to read and post Tweets on Twitter, today I will present you abap2gapps an API prototype in order to interact basically with all Google services that use new OAuth2 authentication.
abap2gapps uses API provided by another Code Exchange project, that we release today, OAuth2.
Wait a moment, what is OAuth2?
You can’t answer the question; you should read this blog OAuth2: Next generation authentication API

OAuth2: Next generation authentication API

OAuth2 is the new Code Exchange project that allows you to authenticate on a web based service provider like Google, Facebook, Microsoft and Foursquare using the OAuth 2.0 protocol.
OAuth 2.0 is the next evolution of the OAuth protocol and is not backward compatible with OAuth 1.0. OAuth 2.0 focuses on client developer simplicity while providing specific authorization flows for web applications, desktop applications, mobile phones, and living room devices. (Wikipedia)
Most of popular on line services like Google, Facebook and Microsoft are already providing access to their cloud using this protocol.

Navigation from POWL to WDA without Object Based Navigation

Prerequisite
Basic knowledge of POWL implementation with WDA. Refer to
this Article on SCN for info:
The problem
In my last project I had to face a technical requirement,
use POWL and activate navigation without portal and OBN.
If you want to achieve this objective using OBN, it is really simple and well documented.
What if I do not use OBN and SAP portal? Are POWLs strictly correlated
to OBN?
