[Former Member]

Hi Experts,

Could you please help me out in the following Graphyical mappings with the real time Examples and data structure.

1. remove context

2. split by value

3. collapse context

4. Use one as many

5. Map with default

6. and few more.

Please awaiting for your kind information.

Hi,

Node Functions are: createIf, removeContexts, replaceValue, exists,

SplitByValue, collapseContexts

Use createIf() to create a tag in the target structure using a condition.

Example: Depending on the value of type (internal or external), the target tag either

internalRequest or externalRequest will be created.

Use exists() to determine whether a particular source field exists in the XML instance to be

processed. If does, exists() returns true, otherwise, false.

Example: In the source, description is optional. However, in the target, description is

mandatory.

Context Change in Message mapping works internally by using queues

If no further elements are imported at a particular hierarchy level, a Context Change is

inserted in the queue Use node functions to handle changes in the message

hierarchy.

removeContexts : deletes all context changes of a queue

SplitByValue: insert additional context changes in a queue

use removeContext() to delete the parent context of an

element.

Use removeContext() to delete all the higher contexts for an element. This deletes all

higher hierarchy levels, so that all elements of the target queue are assigned to a root

element of the source queue.

SplitByValue() is the counterpart to removeContexts(): Instead of deleting a context, you can insert a context change in the source value queue.

Using collapseContexts() replaces all values of all contexts with an empty

string.

Hi,

Please search on SDN before posting the questions it is the best way to get more useful answers.

Refr the blog and thread:

/people/stefan.grube/blog/2006/01/09/the-use-of-suppress-in-the-xi-30-graphical-mapping-tool

/people/claus.wallacher/blog/2006/04/17/replication-of-nodes-using-the-graphical-mapping-tool

/people/sundararamaprasad.subbaraman/blog/2006/02/21/real-example-for-formatbyexample

1. remove context:

You use removeContexts () to delete all the top contexts for an element. This removes all top hierarchy levels, so that all elements of the target queue are assigned to a root element of the source queue.

Advanced user-defined functions can import either just one context into the input arrays, or complete queues. Make your selection by selecting or deselecting the Save Entire Queue in Cache checkbox in the function editor.

2. split by value:

The SplitByValue() function is the counterpart to removeContexts(): Instead of deleting a context, you can insert a context change in the source value queue. You then receive this element for each inserted context change instead of a top node element. However, for this to be possible, the top node source field must be assigned a top node target field and minOccurs must be >0. You can insert a context change in the queue after each value, after each change to the value, or after each tag without a value.

3. collapse context:

Using collapseContexts() puts the first values of all contexts into a context. Empty contexts are replaced with an empty string:

This can be useful if an upper-level node is to be created each time a lower-level node exists, for example. The function is useful in combination with the SplitByValue function.

4. Use one as many

You require the function useOneAsMany() if a field that only occurs once needs to be replicated as often as another field occurs in the outbound message so that the fields can be written to the target structure in pairs as a record.

http://help.sap.com/saphelp_nw04/helpdata/en/2c/2d8c4024d26e1de10000000a1550b0/frameset.htm

5. Map with default

6.copyValue

You use CopyValue() for a frequently occurring element to copy the value of a position in the source structure and assign it to a target field. The value is copied each time the target field occurs in the target structure. However, it is copied a maximum of maxOccurs times

7.createIf

You use createIf() to create a tag in the target structure depending on a condition.

8.exists

You use this function to determine whether a particular source field exists in the XML instance to be processed. If it does, exists() returns the value true, otherwise it returns the value false.

9.Use

You use this function if you need to synchronize two queues of equal length with reference to their context change. The mapping runtime takes the values from the first queue, and the context change from the second queue. If the two inbound queues do not have the same number of values, the mapping runtime triggers an exception.

Thnx
