First, SAP is so vast you will never be able to know every part of it. There are so many functionnal subjects and technologies that this is mind-numbing.
Courses can be used either for a first introduction (but this is costly for such a use) or for extremely advanced subject (better).
SAP is a full environment. The code for most of the content is available. Thus, checking how SAP has done something can/may/will help you understand the technology or the subject. (Btw, a lot of comments are in German...) in-system transaction se80 is particularly useful in this aspect, as it show all related data to a program.
Also, SDNis your friend. forum, how-to, white papers are present... it will help you. A few in-system transactions (se83) are to be used as example for coding technics.
SAP 是由一些聪明人和一些不那么聪明的人编写的。 你无法“理解”事情可能是因为一些非常糟糕的程序员为他不理解的问题构建了一堆愚蠢的解决方案。
SAP 因提出自己的语言或重新利用流行语并添加自己的特殊含义而臭名昭著。 这增加了魔力和混乱。
刚开始，提出问题，尝试一些东西，不要害怕它的规模。 很快你就会变得更好......
SAP is a beast to wrangle down .. some suggestions:
For a programmer: Get a decent ABAP programming book. Most concepts will be pretty familiar, and they give you a good starting point to better understand the system.
For a "business user": Other than going to an expensive course (mostly wasted time/money in my opinion), sit down with a user and have him/her explain too you what they are doing for an hour or two.
For a "customizer": This is where things get really difficult as there are a gazillion of steps and choices and places to change things. Having someone more experienced helps. As you noted, books/articles are mostly not very helpful as they are usually at a loss to explain concepts.
A couple of things to keep in mind as well:
SAP is "so big" that it is impossible to "know it all".
SAP is written by some smart and some not so smart people. Your inability to "grok" things may be caused by some really bad programmer building a bunch of stupid solutions to problems he hasn't understood.
SAP is notorious for coming up with their own language or by repurposing buzzwords and adding their own special meaning. This adds to the magic and confusion.
Just get started, ask questions, try out some things, don't be afraid by the size of it. Pretty soon you'll get better at it ...

我在那里领导 SAP 技术团队部门，该部门是基础、网络和开发的交叉部门。 主要是中间件、端到端以及后端技术
从那里我搬到了 SAP BASIS 团队
然后我搬到了另一家使用 Windows 和 MS SQL 的公司（银行主要是 UNIX 和 Oracle）并且还使用一些不同的 SAP 模块，不同的使用模型和其他各个方面相似但不相同，因此我能够转移并提高我的核心技能集，
我仍然在那里并且仍在学习！
我参加过一些 SAP 和非 SAP 课程。
In brief, this is how I learned about SAP:
Did a 4 year sandwich computer course at University - they didn't even mention SAP
The 3rd year of the University course was a placement year
I got a job within a SAP department in a large bank that had recently implemented SAP
For the first 3 months I traveled all over the UK installing the SAP GUI software
Later I took ownership of the SAP Portal systems and got involved in SAP BASIS. Most importantly I got to know what each of the SAP teams did, which enabled me to discover what I wanted to do in my career
Went back to University for my 4th year (while I did this I did a project for University, which I did based on SAP, so I kept in touch with the SAP department at the bank and visited them most weeks)
After finishing University, I went to work for the SAP department at the bank full-time.
There I lead the SAP Technical team department, which was a cross between BASIS, networking and development. Mostly middleware, end to end as well as back end technologies
From there I moved into the SAP BASIS team
Then I moved to another company which uses Windows and MS SQL (the bank was mostly UNIX and Oracle) and also uses some different SAP modules, a different usage model and various other aspects that are similar but not the same, so I was able to move my core skill-set over as well as increase it
作为一个使用 SAP 14 年的人，我可以告诉你，大多数第 3 方书籍都很糟糕。 最好的书籍来自 SAP America 的出版部门 SAPPress。
学习 SAP 的最佳方法是从合作伙伴处获得 IDES 访问权限，并开始在事务 SE38 中创建 ABAP 程序。 它与学习任何其他编程语言没有什么不同，只是编程语言构造不是像 ECLIPSE 那样的开源/免费软件。 它位于 SAP 的 ABAP 堆栈内。
此外，如果您购买 SAP 培训计划，您将获得一个“S 用户”ID，该 ID 允许访问 SAP 开发者网络，从而实现进一步学习。 这很昂贵，但那些认真的人都有一个 S 用户 ID。
As someone who has worked with SAP for 14 years, I can tell you that most 3rd party books are terrible. The best books come from SAPPress, the publishing division of SAP America.
The best way to learn SAP is to get IDES access from a partner and start creating ABAP programs in the transaction SE38. It is no different than learning any other programming language except that the programming language construct is not open source/freeware like ECLIPSE. It is within the ABAP stack of SAP.
Additionally, if you buy an SAP training program- you will get an "S User" id that will allow access to the SAP Developer Network which will enable further learning. This is expensive, but those that are serious ALL have an S User ID.
We're actually having the same kind of problem. We need to interface our system with SAP and whatever information you can find on your own is not helping much. The only way that has worked for now is to find an experience person who would help us for free (such as our customers who win themselves if they help us interconnect our piece with their SAP installation).
Teaching courses seem to be too expensive to afford when you clearly see that you won't learn much in a few days/weeks. The other option of hiring external SAP consultants is also not considered because of the costs.
I know that they are ready to teach new young graduates ABAP and their system. Or at least were ready, as they stopped employment last year completely.
From some brief time being there (writing a thesis) I remember they have extensive internal portal with message boards and various listing. If you have friends working there you can ask them to publish a private ad asking for some private lessons. Another option is to pick up a student who say started a job there but dropped it after a year or so. This way you could potentially have someone with some knowledge but not costing yet a fortune.

SAP is an ocean & known is a drop. But there's nothing stopping us from knowing it all.
ABAP : There are some great wikis in SDN & help.sap where you can explore ABAP. I'd suggest since you'd explored more on obj. oriented programming, its best suited to learn ABAP Objects. Its much interesting & simpler like C#/Java etc. In SDN you can explore a lot in this wiki. ABAP is a great choice. As an ABAPer, we can solve issues, pretty much enhancements etc, but its mostly COBOLic. I mean procedural & you'd need SAP system to learn it, as there are not pretty much 'free' online compilers available to test & run!
Other Options : As you'd worked prior on MS. Would suggest you to have a look at MS - SAP Duet. Today's job market has lot of professionals in technical aspects & lesser process, functional & management level associates. Click here for more information on SAP Microsoft Duet. Duet Enterprise, a product jointly developed by SAP + MS. It combines the collaboration and productivity supported by MS SharePoint with the business data and business processing functionality of SAP applications.
ByD : Plus if you've some experience in c#, would suggest have a look at SAP ByDesign SDK. Code name : Copernicus. Now released as ByD Studio. This is amazing as the keywords, codes & scripts are more similar like c#. A perspective on this would be available here in this link.

首先，SAP 是如此庞大，你永远无法了解它的每一个部分。 有如此多的功能性主题和技术，令人头脑麻木。
课程既可以用于初次介绍（但这对于这种用途来说成本很高），也可以用于非常高级的主题（更好）。
SAP 是一个完整的环境。 大部分内容的代码都可用。 因此，检查 SAP 如何做某事可以/可能/将帮助您了解该技术或主题。
（顺便说一句，很多评论都是德语......）系统内事务 se80 在这方面特别有用，因为它显示了程序的所有相关数据。
另外，SDN 是您的朋友。 论坛、操作方法、白皮书都在这里......它会对您有所帮助。 一些系统内事务（se83）将用作编码技术的示例。

SAP是一个非常封闭的系统。
如果你想学习SAP，唯一可靠的方法就是参加SAP一些非常昂贵的培训。
SAP is a very closed-end system.
If you want to learn SAP, the only reliable way is to take some very expensive training from SAP.
简而言之，这就是我了解 SAP 的方式：
我参加过一些 SAP 和非 SAP 课程。
In brief, this is how I learned about SAP:
I have been on several SAP and non-SAP courses.

我们实际上也面临着同样的问题。 我们需要将我们的系统与 SAP 连接，您自己找到的任何信息都没有多大帮助。 目前唯一可行的方法是找到一位有经验的人免费帮助我们（例如，如果我们的客户帮助我们将我们的产品与他们的 SAP 安装互连，他们就会赢得自己）。
当你清楚地看到几天/几周内你不会学到太多东西时，教学课程似乎太昂贵而难以承受。 由于成本原因，也没有考虑聘请外部 SAP 顾问的另一种选择。
我知道他们已经准备好教授新的年轻毕业生 ABAP 及其系统。 或者至少已经准备好了，因为他们去年完全停止了就业。
从在那里的一段短暂时间（写论文）开始，我记得他们有广泛的内部门户，其中包含留言板和各种列表。 如果您有朋友在那里工作，您可以要求他们发布私人广告，要求提供一些私人课程。 另一种选择是接一位自称在那里开始工作但一年左右后放弃的学生。 这样你就有可能找到一个有一定知识但又不花很多钱的人。
