The project will be paused because I have reached the main goal of it - find a job as SAP developer. I am employed since 1 March. It may be continued later with more expirience or may not.
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...
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...
It all has been started from the error I've got in my Visual Studio Code environment. I have installed some obsolete packages over npm and Fiori App Generator will not start anymore. This routes me to idea to place the IDE into a docker container. I started looking if such container already exist and found the following: SAP ABAP Platform 1909, Developer Edition Official docker developer environment with HANA 2.0, ABAP 1909 full support of OData v4 and RESTFull API! This is where I want to move my project to and this will be the next task.
