Before you read this article, I recommend first to go through Sravya Talanki's Weblogs Message Mapping Simplified

Part I and Message Mapping Simplified Part II

The graphical mapping provides some useful functions with starting with XI 3.0 SP13:

- The node functions mapWithDefault, formatByExample, sort and sortByKey

- The statistic function index

The function mapWithDefault

This function provides a default value, whenever the source element is not available. This is useful function, when you

want to use the content conversion of the file adapter. Look at this example:

Before SP13 we had to use a combination of the functions exists and if, now we need only one function:

The function formatByExample

This function allows grouping of values of a tag according to values of another tag. Look at this example:

We can achieve this with our new function:

The other nodes are mapped with help of the node functions splitByValue and collapseContexts like follows:

Make sure, that the context of the node ID is set to ORDERLIST in all cases.

The functions sort and sortByKey

Of course these functions are used to sort elements. Let us look at this example:

The elements in tag PRODUCT shall be sorted the same way as the elements in tag ID. As the functions sort and

sortByKey only sort the elements within the same context, we have to use the function removeContexts before sort.

After sort we have to restore the original contexts. We do this with the node function splitByValue The mapping now

looks like follows:

The function indexThis function works like the function counter. The difference is that the function index repeats counting for each

context. Let us look at an example:

We want the tag No to count the positions in an order. For this reason we have to provide the correct contexts. This

can be done by the node function splitByValue. After creating of the correct index numbers, the values have to be

separated to different contexts. This can be achieved as well with the node function splitByValue.

I hope this blog will help you to understand the use of the new mapping functions.

Hi Stefan,

Your blog with clear examples solved my query in the XI forum - ' Help in mapping with 'createIf' nodefunction'.

Thanks,Ashok.

I was reading in SDN library and other sources to try and figure out SplitByValue and could nevermake them work. Your method of removing, adding, and then collapsing context are exactly what Ineeded to go from simple flat input file to a nested hierarchy.

Best regards,

Aaron

Great examples.

Just one comment for formatByExample.

You have to do sorting functionalities first before formatByExample function for data source that arenot in order.

Thanks and Regards,Robert
