change node cardinality in message mapping

[maartenf]

Hello,

I have a question regarding graphical message mapping from iDoc to cXML. It's the first time I do a (fairly) complex mapping so any help is greatly appreciated!

I'm supposed to map a value from the iDoc with 0...10 occurences to a value in the cXML with just 1 instance. This doesn't seem to work because (I think) it tries to map it multiple times and that's not permitted. When testing the error "Cannot create target element /cXML/..." occurs.

Example:

Source node:

<node>

  <value1>012</value1>

  <value2>20120703</value2>

</node>

<node>

  <value1>011</value1>

  <value2>20120810</value2>

</node>

I should map value2 to the external message when value1 = 011. How can I say it should ignore the other node (with value1 = 012) Is this possible in a graphical mapping?

Thanks in advance!

Kind regards,

Maarten

Hello Maarten,

This should be doable using the ifWithoutElse function e.g

value1 --> equalsS --> ifWithoutElse -> removeContext -> Target

Constant: 011 -> /   value2 -> /

Hope this helps,Mark

Hi Mark,

Thank you, this is the solution. I was really close, just didn't have the removeContexts. I'm not sure yet what it actually does, I'm going to look it up now.

Kind regards,

Maarten

Only sometimes Most of the time, you have already posted first haha

This seems the far west, only the fasters survive

Hi Maarten,

Use the mapping like this one:

value1 -> equalsS(011) -> ifWithoutElse(value2) -> target

This should get the job done for you.

Also, have a look at my blog , I believe you might find it helpful to consolidate your knowledge about the basic principles of graphical mapping.
