help on Mapping logic

[Former Member]

Hi,

i am doing a file-file scenario.. some times the source fields might come empty and sometimes with values..

When a source field value is blank then it shouldnt create a field on target side,if it has some value it has to be passed as iti is..

Can you gimme some idea on this.

Use Equal function comparing <empty> value.

When i copied the payload given by user.. and just gave a test using lenght function..its returning 5..

Why is the blank value is having lenght as 5?

Just check for spaces....

have u implemented the logic for your requirement ?

I guess there will be 5 blank spaces (check the xml source), If yes then XI will consider it as value and in that case node will be generated at target side.

But if you don't want to generate the target node for this case, then use the "Trim" function in your mapping just after the source field. You can find "trim" under "Text" function.

Use "IfWithoutEsle", "EqualS", "Constant" and "NOT" functions.. eg.

Logic: If not source equals empty then map source.

Still the field is populated with blank value on target side

Kiran,

A ver basic question, would have appreciated if you have searched a bit and then asked your doubt (if any)

Still..follow the below logic:

Source>equalsS Constant (blank)> Not>Ifwithoutelse->Target

Source> then--

---

>Target

Hi Kiran,

Use mapWithDefault standard function.

Please see the below link, it might be helpful to you.

Rajesh,

MapwithDefault wouldnt work here as Kiran doesnt want to create the target field when the input is blank.
