The diagrams are generated and displayed from the SAP GUI without any further settings.This program generates UML class diagrams automatically from existing ABAP code.

We want classes with single responsibility, where the abstractions are visible in the code LCL_PRICE : Process( )Įnd can generate sequence diagrams using transaction SAT.ĭiagrams are more expressive than code but tools are needed. ABAP code using FORM as modularization unit is easier to reason about if the code reflects the hierarchy of the abstraction levels (top down Transaction ĭescribe the static structure (topology) of the code. This diagram type is well suited for the description of processes. Real programmers do not read documentation: go to the PlantUML online server, -> ContractHeader With the hope that we will see more diagrams, as the costs/effort to create them are reduced. I present an ABAP interface to the PlantUML web service in the appendix. The API can be called from many programming languages. The concept of working with plain text should resonate with programmers. At least 2 existing blogs reference PlantUML on SCN: PlantUML (site ) is a mature project integrated with many content management systems, text editors and other tools.

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. I will propose to select one and get used to it, so the effort needed to create those diagrams is reduced.

Many visualization tools are available, some free (search the web for free UML tools), others with a price tag and easy to use templates. Would take too much time, we will see copy/pasted source code in the documentation. Without appropriate tools, creating diagrams (e.g. OK, I have to work on my skills and do image pre-processing, but this is probably as easy as creating an annotated screenshot. The dynamic behavior of code: we want to emphasize interfaces in a sequence diagram. (or timing diagram)Ĭreate a rough sketch on paper by hand, capture the picture with a phone/camera and upload it.

Modularization elements: we want to provide a bird's-eye view of the code structure using class diagrams (object diagrams, composite structure diagram).

Requirement specifications: we might want to visualize requirements in a use case diagram (also check: activity diagrams, state diagrams).

To decide which diagram type communicates our intent best, we must understand its essential features. Nowadays, the Unified Modeling Language ( UML) is an established notation to visualize designs using following diagram types: So many disparate notations were created that they had to be standardized. It helps to reason about software and eases knowledge transfer. Each diagram type communicates intent in a special way.

Evidence from ABAP blogs suggests developers communicate to their audience usingįor most of us, a diagram is easier to consume than text.
