关于学习的浅浅思考

所思所想所见所闻 No Comments »

一直都在思考学习到底是为了什么,学习的本质是什么?输入是什么?输出是什么?

不管学习的过程或者结果怎样,最后总也还会剩下些概念。

因为一般的说法是学习的结果就是锻炼思维能力,掌握思考的一般和特定方法。

我也觉得有道理,只是还是没有很清楚其中的细节。于是就一直都在思考什么是思维能力。

科学思维可以简单分为逻辑思维和非逻辑思维。

而关于逻辑思维的方法有很多,其中很重要的有归纳推理和演绎推理。

归纳就是从个别到一般原理的过程。分为完全归纳和不完全归纳(分为简单枚举和数学归纳)。

我们学习的知识很多都是前人归纳推理的结果。

我们学习以后会最终会留下很多的概念。这些概念最终会帮助我们进行演绎推理。演绎就是从一般到个别的推理方法。其主要形式为三段论:大前提、小前提、结论。

由此我们得到一个思维的转化链条:概念―〉判断―〉推理―〉概念。

逻辑思维的主要方法有:〈比较、归类〉、〈类比〉、〈归纳、演绎〉、〈分析、综合〉。

非逻辑思维的主要方法有:〈想象、直觉、灵感〉。

学习就是为了得到思考(或者思维)的原动力。

(续)最近想读的书,正在读的书,正在做的事情。

回顾去年:《MRPII/ERP原理与应用》早看完了,《论语新解》也翻过了,刘毅的单词书也背完一本了。
继去年IBC项目完了以后,10月就开始做FI1/US1的项目,到这月刚warranty阶段结束。工作方面提高还是蛮多,我的manager也说希望我至少在HP再做2年。在这接下来的两年里面,除了提高实际工作经验外,我还希望能通过公司拿到一个PA Financial Consultant认证,一个PMP认证,当然,还有自己在读的上海交大的工程硕士的学位。而最近正在读的书也大多跟硕士课程有关:《软件工程—实践者的研究方法》、《UML和模式应用》、学校图书馆借的《UML基础与Rose建模案例》、《工程硕士研究生英语》、《算法引论》和《PMBOK2008》,太学术化了。所以我又到卓越订了几本想读的书:《当下的力量》、《爱你就像爱生命》、《历史是个什么玩意1》、《第一本哲学漫画书》和《你是那人间的四月天》。
如今除了工作以外的时间基本被学校学习填满,但是很充实,算痛并快乐着吧,也接触到了新的方面的自己以前不会碰到的知识,虽然好像一直在用。这也许就是传说中的系统化吧。有朋友问,干嘛去读这个学位,对你有意义吗?我回答:1. 算是对父亲和对自己的交待,拿个硕士学位,过了30岁估计就更不太会想读了。2. 通过学校平台接触到新的知识或者新的朋友。3. 感觉还有很多想不明白的东西,希望能想明白。有人说过程更重要,有人说结果更重要,我觉得是不同的人说不同的话,反正我是要痛苦的享受这个过程了。
(期待明年的这时候又有新的进步,加油吧!)

Transport guide tips for different SAP objects

06 SAP Basis No Comments »

You may be wondering if you can transport certain SAP objects, and if possible, how?

Here are tips for different objects:

1 LSMW There are 2 ways for transporting LSMW data from a system to another.

1.1 Export/import This method gives you the opportunity to select the subprojects or objects you want to transfer. Hence you don’t transfer the object a colleague might have created and that should stay in development system. LSMW -> Extras -> Export project

1.2 Transport request With this method, you can transport a LSMW project in full (you can not select the objects you want). With this method, the project will be transported as any other SAP object in a transport order.
LSMW -> Extras -> Create change request

2 Program variants
If you have several program variants in a development system that you want to transport, use the following method to transport them:
Execute program RSTRANSP (via se38) and inform the program and/or variant names (you can transport variant of several programs in one shot).

3 Layout In some transactions, one can save layout of the screen (sort, filter, … criteria).
These layouts can be transported: In the required transaction, when your layouts have been saved, go to Settings -> Layout -> Layout Management. Select the desired layouts and go to Layout -> Transport… There you can add your layouts in existing TO or create a new one.

DB data
In some unusual cases, you might have to transport data of a SAP table.
Go to transaction SE16, select your entries and go to Table entry -> Transport entries. It’s only possible for some tables…
If you cannot do it that way, you have to create a Workbench transport order with transaction SE10. When created, click on it, go in menu Request/task -> Object list -> Display object list.

Go in modification mode and add a new line with:

PgmID = R3TR
Obj = TABU
Object name = Name of your table

Double-click on the created line and, depending on your need, put ‘*’ in the key field or double-click on it and select the key you need to transport.

4 Queries
Queries, datasets and user groups can be exported/imported between the systems thanks to the program RSAQR3TR.

5 Standard texts
Standard texts used in SAPScript (created with transaction SO10) can be included in transport orders. You have to create a Workbench transport order with transaction SE10. When created, click on it, go in menu Request/task -> Object list -> Display object list. Go in modification mode and add a new line with:

PgmID = R3TR
Obj = TEXT
Object name = TEXT,,ST,

Example :
R3TR / TEXT / TEXT,YMM_MEDRUCK_MAIN_16_EC,ST,F

You can also copy a Sapscript object (like standard text) with the program RSTXCPFS.

How to transfer a executable report from dev server to prd server? And that report contains one user defined view. I want to transfer *the report and the view* from dev to prd.

At the time of creating the report itself it will ask you to select the PACKAGE.

Here you should select the package instead of $TMP package, which for transporting the objects and create a new request and save it. If you want to give a TCode for the program that you have created just give SE93 in the GUI Window and give the TCode name there and enter the Create button. there you should give the name of the object or program that you have created and save it. After completing this go to SE09 TCode and select the MODIFIABLE Check box and press DISPLAY Button.

In the next screen you have to select the Request that you have created and click the check syntax icon. If no errors are there then you can press the Release Directy icon to transport the request to the Quality system. From there it has to be transported to the Production System. The latter part BASIS will take.
