Hi Expert,
actualy cardinality is nothing but it is selection of value as well as instatiation of node..
4 type of cardinality are there....
0:1----it behaves as not instatiated but may be created upto 1 element...
1:1-beahaves as it is instatiated but will create upto 1 element.
0:n--as it is not intatiated and will create upto nth element
1:n--as it is instatiated but will create upto nth element..
Actualy it is used in Value node at time of creation of any collection of data...it is one of the property of value node in contetx...before doing any thng of node..you have to set cardinality value as above....
thanks

Hi Subhoda,
CARDINALITY tells the min. and max. numbers of elements a node may contain.
Theare are 4 properties for this.
0:1 - The node contains zero or one element.
1:1 - The node contains only one element.
0:n - The node contains n elements
1:n - The node contains one or n elements.
In webdynpro the context node act as an Internal table. To control the number of elements in the context node, the cardinality properties are used. If you want to store only one element, use 1:1, the same way with others.
Hope this answers your query. If not reply back...
