Declaration of the Context

At designtime, the context represents a description of the structure of the required value sets. Each attribute is typed and is only available once.

At runtime, these structured shells are filled vith values. A multitude of values can be contained in the context for a single attribute when, for example, depicting tables. You can determine use the cardinality of a context node to determine at design time whether or not you want to permit a multiple value set for a context attribute at run time.

Context nodes with a cardinality of 0..n or 1..n are designated as multiple nodes. This means that a single context attribute of a multiple node can adopt a multitude of values at runtime. To enable you to work sensibly in this kind of multidimensional context, the Web Dynpro ABAP Framework provides thesingleton and leadselection properties.

There are several ways to fill a context with values at runtime (see Filling the Context). However, a method is called in each case. One of these options is the supply function (see Supply Function).

To enable the parallel use of context elements in different views and the transportation of values from one context to another, you use context mapping (see Context Mapping).
