mapping requirement.

[Former Member]

Hi Folks,

Here i am facing a problem regarding the mapping in XI. i just like to know whether my requirement is possible in message mapping or not.

my requirement is -

---

i am having 5 fields under one node on the sender side and 5 fields under one node on other receiver.

its a simple one to one mapping.

the specific condition is that i need to create an element on the receiver side when it is getting some value from the sender side... else the receiver element is not to be created.

even i tried with the mapping as

Sender--->exists--->createif--

---

> receiver.

but it is not passing the value to the receiver element.

the condition is based on the value......

if we get the value to an element on the sender side then that particuler element on the receiver side need to be created . else dont wnat to create the element at all on the receiver side .

please help me ......

Regards,

Sridhar Dasari.

Sridhar,

If you could give the source and target strcuture and the condition, it could be easy for us to suggest.

Hi Raj,

Thanks to have a look on my thread.

the sender structure is

--> Sender

Fld1

Fld2

Fld3

Fld4

the receiver structure is

-->Receiver

feild5

feild6

feild7

feild8

Now coming to my condition

if the elements (Fld1,Fld2,Fld3,Fld4) in the sender structure gets some value from the sender then only the respective elements (feild5,feild6,feild7,feild8) need to be created. else not to create the element at all.

for example if i am passing some value to Fld1,Fld2 and Fld3 and not passing any value to Fld4. then on the receiver side we need to create the elements feild5,feild6,feild7. we dont have to create the element "feild8".

we need to create the elements and we have to pass the values also coming from the perticular input elements. please help me.

Sridhar,

I believe it's pretty simple. Just map directly Field1 to Field 5, Field2 to Field6, Field3 to Field7, Field4 to Field8.

The only thing u need to do is, make the target elements Field5, Field6, Field7, Field8 occurrences as 0..1

This would help u to achieve the logic, am I right?

Hi,

Use the below logic.

input fields f1,f2,f3,f4 & constant with value "null" dont put any values in constant function -> equals-> not->createif->target.

this will repeat for all input fields.

Hi Raj,

i tried the procedure you suggested. but still it is creating a node for the blank values on the receiver side. i dont want to send any blank value to the receiver.please look into this.

Hi chirag,

i tried your procedure tooooooo.... but its giving the runtime exception while testing. no matter if i give a value to the input or if i dont provide any input. it is giving the runtime exception. please have a look into this.

Sridhar,

Not exist is entirely different from the field if has blank values.

Let the occurrences be 0..1, and follow the same logic as provided by Chirag. It shouldn't be null, rather it must be empty constant -ie Constant function with no values in it.
