Shakif,

Check these weblogs where sravya has explained with examples on this:

Hi Shakif,

<b>CONTEXT CHANGE</b>

Please go through these links which clearly explains context and context changes in mapping.....

<b>REMOVE CONTEXT</b>

Remove context removes all the higher-level contexts of a source field thereby delete all hierarchy levels and generate a list.In simple form

removes all top hierarchy levels, so that all elements of the target queue are assigned to a root element of the source queue

<b>SPLIT BY VALUE</b>

The SplitByValue () function is the counterpart to removeContexts(): Instead of deleting a context, we can insert a context change in the source value queue. We 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. A maximum of minOccurs top node target fields can be inserted here.

We can insert a context change in the queue after each value, after each change to the value, or after each tag without a value.

refer this for node functions

Consider the Same above example.

Instead of doing Context Change , wht I can do I can use RemoveContext wht happens it will remove all the context's of Billing amt and aligns them in same context level.

Bill_amt -

---

>RemoveContext-->SUM->Target.

Note:Please don't think from the above example that Context change is equivalent to RemoveContext it all depends on the node level where u are applying these functions.

SplitByValue:

Consider in the queue I'm having the values like

ABC

DEF

GHI

So for each value u want to insert contextchange so if you apply splitbyvalue, then

ABC

<b>[ContextChange]</b>

DEF

<b>[ContextChange]</b>

GHI

Hey

Split by value is used to insert a context in your structure whereas RemoveContext is used to delete all the top contexts of and element

Thanx

Mohamed,

Context Change :Consider the below example, in that example I'll tell u the use of context change.

<MT_Source>

<Order_detail>

<Order>

<Inv_no>10009</Inv_no>

<Bill_amt>900</Bill_amt>

</Order>

<Order>

<Inv_no>10009</Inv_no>

<Bill_amt>1000</Bill_amt>

</Order>

</Order_detail>

</MT_Source>

In target there is requirement that I need to sum all the Bill_amt.

If you look the context og Bill_amt each one is in different context. So I can apply context change to Bill_amt in order to make all the Bill_amt in same context and I can do my calculation.

Bill_amt[Change Context-Order_detail] ->SUM->Target.

Hope it clears a little bit!!!!

Best regards,

raj.
