Message Mapping-Node Function

Question

Dear All,
This is a problem in mapping, we are facing.
Source Structure
Item------Occurance= 1 to Unbounded  (Level 1)
           Garment--- Occurance=1 to 1     (Level2)
Target Structure
target_Item--- Occurance = 3 to 5 (Level1)
             target_Garment--- Occurance=1 to 1    (Level2)
Source Data
<Item>
      <Garment> Blazer </Garment>
</Item>
<Item>
      <Garment> Blazer </Garment>
</Item>
<Item>
      <Garment> Blazer </Garment>
</Item>
<Item>
      <Garment> Shirt</Garment>
  </Item>
<Item>
      <Garment> Trouser </Garment>
</Item>
Expected Target Data
<target_Item>
          <target_Garment> Blazer </ target_Garment>
</target_Item>
<target_Item>
          <target_Garment> Shirt </target_Garment>
</target_Item>
<target_Item>
          <target_Garment> Trouser</ target_Garment>
</target_Item>
Mapping Done:-
Item -
> target_Item
Garment -
>. Remove Context -
> Split By Value(Value Change) -
> Collapse Context -
> Split By Value(Value Change) -
> target _Garment
But we are getting the following error.
Cannot produce target element /ns0:sdntarget/target_Item[4]/target_Garment. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd
But when we see in “DISPLAY QUEUE” in the mapping Editor, every thing is showing as desired.
Can some body suggest, where we are wrong.
Regards,
Navneet

Hi,
As correctly said by Swarup change the occurrence.
What u did wrong is:
Item -
> target_Item -this mapping is not correct as from source u r getting four item hence the target_item will be generated 4 times.
Garment -
>. Remove Context -
> Split By Value(Value Change) -
> Collapse Context -
> Split By Value(Value Change) -
> target _Garment - this will generate only 3 times based on ur logic.
because of this u r getting error target_item[4].
use the below logic:
item-target_item
garment->splitbyvalue(value change)->collapse context-> target_item.
garment-target_garment
garment->splitbyvalue(value change)->collapse context->splitbyvalue(eachvalue)->target-garment.
