OOpenFriends - first classes as MVC pattern

 


    The first sprint will end at 10 Nov and most of the tasks are almost completed. The accounts table is created and first ABAP classes are written. I have used the following article to get myself familiar with the ABAP implementation of most usefull design patterns 

http://zevolving.com/category/abapobjects/oo-design-patterns/ 

    In spite of the fact that the article seems to be old it will give a good overview about. I have choosen classical MVC pattern for OOpenFriends classes, but with some differencies from the article code. So I have moved the attributed to the private section, adding corresponding "getter" and "setter" to implement some incapsulation. Objects of model class will get the data from database and controller class is aggregating the objects of model classes (only accounts at the moment but also other entities in the future). 

UML - MVC Pattern in OOpenFriends

    Now we have Model and Controller parts implemented in classes. View part may be implemented as dynpro, abap programm with alv or any other kind of UI (f.e. Fiori). This will be the next step and the last task for this sprint.

I have also migrated Kanboard to GitHub project and opened it for reading to all https://github.com/users/msminakov/projects/3

Getting started with SAP Fiori and OData on local SAP ABAP Developer Edition VM

Image
    I continue developing the OOpenFriend project and the next step should be the first fiori elements list page for accounts as proof of concept. But does my local developer environment support fiori at all? Lets clarify this. From the OpenSAP course we can get following architectural overview Fiori elements app need OData services to work, s o we need to implement OData services first. And also I need SAP Gateway, where these OData services may be placed and run. OData services may be developed in Cloud using CAP and on-premise using RAP - ABAP RESTful Application Programming Model. Lets take a look on requirements of RAP and here is the first problem:  We need Application Server ABAP 7.55 SP03, but I have only ABAP 7.52 SP04 on my developer edition VM. And there is no later versions of ABAP Server VM on SAP Trials and Downloads since 2018, so I suppose later versions will be avaiable in Cloud only.       Okey, lets use, what we have. There must be a...

Running Fiori elements App on local VM with SAP Developer Edition

Image
    I would recommend to start reading this topic with my previous article    Getting started with ODATA      In the previous part I have created a CDS view and exposed it as OData service. Now I want to build frontend as Fiori elements list report object page on this OData service. Using the standard tutorials for setup Visual Stusio Code and setup the prerequisites for SAP Gateway, the first fiori app was generated.      But it was too early to be glad, because the preview of the application in the browser did not show any data.       Good, F12 says for the error request that we have to look into /IWFND/ERROR_LOG (do not forget to put /n before the transaction name, othervise it says "no such transaction"). Error log contains the error: No service found for namespace '', name 'ESH_SEARCH_SRV', version '0001'. After some googling I found and implemented the following solution from the help article: Activate OData ser...
