What do you do? Most likely, you would check to find any existing reports delivered with the system (or
already written for this client) that provide the information the Operations Manager wants, or that can be
copied and revised to fit her needs. If you don’t find any, you might then look into the appropriate
reporting system — in this case, the Plant Maintenance Information System (PMIS) — to see if you can
adapt it. In this case, however, you can’t find the report, and you can’t cobble one together from existing
ones. You must write a report or an ABAP Query to fulfill the requirements.
你该怎么做？通常的，你会检查系统中运行的，能够提供这个业务经理所需信息的现存报表（或者
是已经为这个client写过的），或者可以在复制和修改后能符合需要的报表。如果没有找到，你也许
会在适当的报表系统——例如，工厂维护信息系统（PMIS）——中看看是否能找到合适的。即使
这样，你仍然无法找到报表，或者无法从现存报表中找到可修改的，那只能写一个报表或者一个
ABAP查询来实现这个需求。
Now, suppose the Operations Manager asks if you can somehow add just one more little function to her
Create Measurement Documents transaction: paste the associated sales order number into the MDoc text
field. This scenario requires you to create an enhancement. In both the first and second scenario, you’ll
need access to specific data from the database tables. How do you find that data with just the screen fields
as your guide? We all know the information associated with a transaction is stored in several (sometimes
many) related tables. So, when you need several fields from a transaction for a report or an enhancement,
you may need to find many of the transaction’s tables and establish the links among them. Those links are
often not obvious.
现在，设想一下业务经理问你是否以某种方式在《创建计量单位文档事务》中增加一个小小的功能：
向MDoc文本字段中粘贴相关销售订单号。这个要求需要你创建一个增强功能。在前面两个情形中，
你都需要访问数据库表中的特定数据。你怎么以屏幕字段做指导来找到这些数据？我们都知道与一
个事务关联的信息都存储在几个（偶尔还会是很多个）相关的表里。这样，当你需要在报表或增强
功能中使用一个事务中的几个字段时，你需要找出许多事务的表并在它们之间建立关联。这些关联
通常都不会很明显。
I’ve come across these very situations on numerous occasions while working for several clients with the
SD, MM, IM, WM, and Service Management (now called Customer Service) modules. Over time I have
gathered suggestions from colleagues and developed some techniques myself to find the data I needed. I
will share these techniques — 18 of them in all — with you now.
我曾经在众多场合遇到这些情况，有时需要同时在SD、MM、IM、WM和服务管理（现在叫客户服
务）等模块对多个client进行工作。随着时间推移，我收集了同事和自己在开发中寻找需要数据的建
议。我现在来跟你分享这些技巧——共18种。
（再注：在 rev1.1 里，加入了我自己收集到的另一种方法，第19种。相信做为读者的你，在以后
的工作中也会不断发现更多更好的方法，不妨也发表出来，让更多的人学习。）
（三注：距前一个版本翻译完成已经两年半了，在这期间，随着经验积累，对文章中提到的方法又
有了更进一步的理解，都在 rev1.2 里详细说明。）
