Mapping problem

[Former Member]

Hi guys!

I have following mapping issue:

source:

<a/> (1..1)

+<b/> (1..n)

++<c/> (1..n)

+++<d/> (1..1)

target

<at/> (1..1)

+<bt/> (1..n)

++<ct/> (1..1)

I need to have mapped b->bt, that's for sure, because I need so many target elements. However, in each b is c n-times and always contains the same value in context of b. I need to achieve, that ONLY FIRST D will be in ct.

When I create mapping: constant->ct (creates only 1 ct) I do not get values d from context of b! I get them all in order! Example:

<a>

<b>

<c>

<d>1</d>

</c>

<c>

<d>1</d>

</c>

</b>

<b>

<c>

<d>2</d>

</c>

</b>

</a>

I get

<at>

<bt>

<ct>1</ct>

</bt>

<bt>

<ct>1</ct>

</bt>

</at>

I need to get:

<at>

<bt>

<ct>1</ct>

</bt>

<bt>

<ct>2</ct>

</bt>

</at>

Why it ignores the context and takes all values of a? I need the first one of context b, and b is mapped correctly to bt!

Any help appriciated!

try setting context of d to b. bcoz you want to produce ct the same no of times as that of b

Mugdha, how do I do that?

Hi Olian,

As I told earlier you have to change the context to b.

You can right click on d in your mapping editor and you will get the option context and click to b.

d(context to b)-->collapseContexts-->bt
d(context to b)-->collapseContexts-->SplitByvale-->ct

Shubhankar, sorry, but there is no option oh change context to b. If I click d node on the source structure, I get only:

Where Used

Copy Path

Dependencies

No context change.

We're on PI7.0

Don't click on source structure. Click on Data-Flow editor.

Well, there is no need to use node functions. It was enough to link it directly , just context of d had to be changed to b. Shubhankar, but for your patience, you've got 10pts

Thanx!

Hi Olian,

d(context to b)-->collapseContexts-->bt
d(context to b)-->collapseContexts-->SplitByvale-->ct

And tell me your result.

Thanks

Shubhankar, this doesn't work. I get all ct nodes in the first bt node.

What is collapseContexts good for?

Hi Olian,

But you have 1..1 for ct node and then how are you getting multily ct nodes under bt node.

See the below link for collapseContexts

Shubhankar, you're right, sorry. It had to be 1..10 occurence and need only 1 node. Olian

try using collapseContext() while mapping ct in the target. Play around with context
