I would like to give you simple example for removeContext()

source structure(please note levels)

-->Header

-

---

>Item

-

---

>MatGroup

target structure

Header

-

---

>MatGroup

To produce MatGroup in target below level Header you will use mapping as

MatGroup->removeContext->MatGroup(Target)

This will remove the top level hierarchy of MatGroup from source and make you feel as MatGroup coming as child of root node..

collapseContext() is well explained by experts

Hi Ramu,

Remove context : It is important where we are using this std fuction im mapping

if you map the source field with remove context and map to an UDF , here the context changes will be removed and delete all the top contexts , so that all the target queue context will have one root and all elements without context change.

Collapse context :

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

in general we need to use this kind of function , when ever you want to send all the first values , first one as each individual .. to the target

hi Ramu

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
