Introduction
Evidence from ABAP blogs suggests developers communicate to their audience using
- A lot of (technical) text,
- (ABAP) code blocks,
- Some (annotated) screenshots,
- Few pictures,
- Little or no diagrams.
For most of us, a diagram is easier to consume than text. Each diagram type communicates intent in a special way. It helps to reason about software and eases knowledge transfer. So many disparate notations were created that they had to be standardized.
Nowadays, the Unified Modeling Language (UML) is an established notation to visualize designs using following diagram types:
UML Essentials
To decide which diagram type communicates our intent best, we must understand its essential features. I will single out
- Requirement specifications: we might want to visualize requirements in a use case diagram (also check: activity diagrams, state diagrams)
- Modularization elements: we want to provide a bird's-eye view of the code structure using class diagrams (object diagrams, composite structure diagram)
- The dynamic behavior of code: we want to emphasize interfaces in a sequence diagram. (or timing diagram)
and refer to some tutorials, e.g.
How to Create Diagrams
Create a rough sketch on paper by hand, capture the picture with a phone/camera and upload it.
OK, I have to work on my skills and do image pre-processing, but this is probably as easy as creating an annotated screenshot.
Without appropriate tools, creating diagrams (e.g. like this one)
would take too much time, we will see copy/pasted source code in the documentation. Many visualization tools are available, some free (search the web for free UML tools), others with a price tag and easy to use templates. I will propose to select one and get used to it, so the effort needed to create those diagrams is reduced.
Try PlantUML
Let me introduce you to the open source PlantUML tool that creates UML diagrams from plain text. It uses the graph visualization software Graphviz to lay out diagrams of remarkable quality.
PlantUML (site http://plantuml.com/) is a mature project integrated with many content management systems, text editors and other tools. At least 2 existing blogs reference PlantUML on SCN:
- https://blogs.sap.com/2013/08/21/auto-generating-uml-diagrams-from-abap-code/
- https://blogs.sap.com/2014/12/19/doxygen-and-abap/
The concept of working with plain text should resonate with programmers. The API can be called from many programming languages. I present an ABAP interface to the PlantUML web service in the appendix.
With the hope that we will see more diagrams, as the costs/effort to create them are reduced.
State Diagram
Real programmers do not read documentation: go to the PlantUML online server, enter:
@startuml
[*] --> ContractHeader
ContractHeader : Screen 201
ContractHeader --> Partners
Partners : Screens 102, 101, 201
Partners --> ProcessItems
state ProcessItems {
ItemsOverview --> ItemsDetail
ItemsOverview : Screens 220, 221
ItemsDetail : Screens 211
ItemsDetail -> ItemsAddData
ItemsAddData : Screens 212
}
ProcessItems --> [*]
@endumland get this!
Activity Diagrams
This diagram type is well suited for the description of processes. ABAP code using FORM as modularization unit is easier to reason about if the code reflects the hierarchy of the abstraction levels (top down decomposition).
@startuml
start
:Init Transaction;
:Query Documents
- Fecth Header
- Authority Check
- Fetch all items
- Additional Data;
if (Entry found?) then (View)
:ALV Display;
else (Error)
:Message;
endif
stop
@enduml
Class Diagrams
describe the static structure (topology) of the code. We want classes with single responsibility, where the abstractions are visible in the code structure.
@startuml
LCL_FILTER <|-- LCL_FILTER_NULL
LCL_FILTER <|-- LCL_FILTER_CUSTOM
LCL_FILTER : accepts( )
LCL_FILTER_NULL : accepts( )
LCL_FILTER_CUSTOM : accepts( )
@enduml
You can already generate UML class diagrams using report UML_CLASS_DIAGRAM if you have installed the correct Java OCX plugin on your machine. Find a custom version using PlantUML in the appendix.
Sequence Diagrams
This diagram type visualizes coupling between objects. Code is easier to change when objects working have minimal knowledge about each other.
@startuml
hide footbox
actor User
User -> LCL_PRICE : Process( )
LCL_PRICE -> LCL_INFREC : Transfer( )
LCL_INFREC -> LCL_BDC : PRICE_UPDATE( )
box "Internal Service" #LightBlue
participant LCL_INFREC
participant LCL_BDC
end box
@enduml
You can generate sequence diagrams using transaction SAT.
Summary
Diagrams are more expressive than code but tools are needed. Try PlantUML at http://plantuml.com/.
Appendix
- This program generates UML class diagrams automatically from existing ABAP code.
- The diagrams are generated and displayed from the SAP GUI without any further settings.
- Local class LCL_PLANT_UML implements access to the PlantUML web service.
