Some consulting questions and answers raised by friends who lack programming foundation and want to change careers in ABAP development post

Recently I received a consultation from a friend , About non programming professional background, I want to change careers ABAP Feasibility and specific direction of development post , I think the problem is representative , Because I have received similar consultation before . So write a separate essay to share . This article only represents the author's personal views , and SAP It's not official .

1. ABAP What is the general career development of the development post ？ Is it true “ The older, the more popular ”？ What is the current market demand ？

We deploy locally (On-Premises) Based on the ABAP Of SAP For example, products , such as SAP CRM,SAP ERP,SAP S/4HANA, In these products ,ABAP It's a development language , It's also SAP The running environment and platform of the application . meanwhile ,ABAP The developed applications are all applications for enterprise users , therefore ABAP Developer , Not only need to understand and master ABAP The development technology of this programming language itself , Also have business knowledge in your field of work ( That is, the module knowledge commonly used in the industry ) Know something about .

Personally think that , If you go pure ABAP Development route , That is, we are only satisfied with delivering the development tasks assigned by others , Then the ceiling of development is relatively low . Personally think that SAP The real value of consultants is to help customers sort out and integrate their enterprise business processes , Make it work perfectly in SAP On the system . and ABAP If developers are working , Be able to make full use of work advantages and constantly enrich their business knowledge of relevant modules , In this way, the development of controls will be broader . In fact, many successful SAP practitioners , All go technology + Business , perhaps technology + management Comprehensive development route . Business and management knowledge , Compared with pure development technology itself , Is not devalued with the passage of time , It is worth long-term investment and hard work , Of course, technology also enters SAP A stepping stone to the industry .

as for ABAP Market demand of development consultants , because Jerry yes SAP Developers of the Institute , I'm not clear about this one . Welcome other insiders to comment and share .

2. If there is a zero basis , How long does it take to learn to enter the industry ？

ABAP Build the development environment , Relatively speaking, it is not like other programming languages, such as Java,JavaScript These are easy to build ： You need to install one locally ABAP The server , Or find some installed ones for learning through other channels ABAP The server .ABAP Development technology itself is not too difficult compared with other popular programming languages , But relatively speaking, there are less Chinese materials , The absolute number of users is also smaller . Zero base words , Study ABAP Relatively speaking, I think it is better than learning Java and JavaScript It's a little more difficult , because Java and JavaScript Course of study , Whether it's text or video , There are already many on the Internet , And these two programming languages , According to the tutorial, you can quickly write some applications that can be run and used in a short time , Learners can easily get positive feedback . and ABAP There are relatively few learning materials in this regard .

So zero basic learning ABAP Words , It's best to have an experienced person to guide , Or at work , Edge learning , Side entry . If you rely solely on self-study , It may take longer .

3. What is the specific learning route ？

SAP There are standard ABAP Training courses ( pay ), The course number and description information are as follows ：
