[prabhu_s2]

I'd checked on help.sap. Pls no links.

Hi

Try this

refer here /people/sravya.talanki2/blog/2005/12/08/message-mapping-simplified-150-part-ii

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

http://help.sap.com/saphelp_nw04/helpdata/en/58/cd834014d26f1de10000000a1550b0/content.htm

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

Thanks

thkx sridar. i did check on those link but maybe i'm not clear with the explanation given there? i'm looking for a kind of a simple mapping scenario on how it is useful and how it differs from removecontext

Prabhu,

In this thread go to page 2 and see my reply. I gave the soln with Collapse context with results too. Have a look.

Hi

Below is only Difference between Remove Context and Collapse Context

XML File Input:

?xml version="1.0"

encoding="UTF-8" ?>

<Test_Out_Remove>

<header name=“A">

<item>A.one</item>

<item>A.two</item>

<item>A.three</item>

</header>

<header name="B">

<item>B.one</item>

<item>B.two</item>

</header>

</Test_Out_Remove>

After Using Remove Context Output:

<?xml version="1.0"

encoding="UTF-8" ?>

<Test_In_Remove>

<item>A.one</item>

<item>A.two</item>

<item>A.three</item>

<item>B.one</item>

<item>B.two</item>

</Test_In_Remove

Cpllapse Context

xml instances ( pARSE ---> ) tAG

Item(1,2,3,4,5,6)

Using

&#8595;Collapse Context

Tag (Result Tag and Item see side)

Item ( no values)

Above XML file after parser for Tag and Item number,After That Using Collapse Context It Gives The result like Tag as it is and Item as a Empty value.

Might be useful

yes sure with a simple example.

[justin_santhanam]

Prabhu,

Consider my source structure looks like

<EmployerInfo>

---<Location>

-

---

<Region>Trichy</Region>

-

---

<Region>Bangalore</Region>

-

---

<Region>Madurai</Region>

---</Location>

</EmployerInfo>

<EmployerInfo>

---<Location>

-

---

<Region>Andhra</Region>

-

---

<Region>Delhi</Region>

-

---

<Region>Mumbai</Region>

---</Location>

</EmployerInfo>

In my target structure I want only the first region for each employerinfo.

So what happens if you give Region->CollapseContext->SplitByValue--->Region

Then u will get the target structure as

<EmployerOrg>

-

---

<Region>Trichy</Region>

</EmployerOrg>

<EmployerOrg>

-

---

<Region>Andhra</Region>

The purpose of CollapseContext is to take the first value from the queue in the same context level.

Trichy

Bangalore

Madurai

<b>[Context Change]</b>

Andhra

Delhi

Mumbai

Results after collapse context

Trichy

<b>[ContextChange]</b> ---Bcoz I gave SplitByValue.

Andhra

I hope it clears a bit!!!

raj.
