mapping issue

[Former Member]

In Mapping, Can I use one Target field as source to map to another? In my true scenario, I map the unit price from source xml to target xml, amount from source xml to target. in target xml, there is a total field equal to unit price multiply amount. but the mapping rule in source unit price and source amount is a little complex. I just want to use the target unit price and target amount as source to map the target total. is it feasible? can I use target field as source?

You can copy the path where you have caluclated the target amnt and unit price and multipy.

I do another new mapping, take target as source, take target as target,then map these two same xml structure

Hi Spring,

>. is it feasible? can I use target field as source?

No, your target field cannot be the used a source in the same message mapping, when using Graphical Mapping.

From SP14, onwards, you can use Global Variable s in your Graphical Mapping , you can try to use if using a global variable can solve your problem.

For info on how global variables can be used, check this blog,

In Graphical Mapping, you will have to form the logic using only the source fields and <b>cannot use the target field as the input to your user defined function.</b> The only way this would be possible is to use Java Mapping.
