How to export parameters from Message Mapping

[samantha_nez]

Hi,

I am trying to export parameters from a Message Mapping.

I have defined a export parameter into Message Mapping Signature as string type called ERROR_TEXT. According to blog:

[https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/8654] [original link is broken] [original link is broken] [original link is broken];

values can only be assigned to export parameters in user-defined functions.

How could I assign a value to ERROR_TEXT from my user-defined function? How could I manage import/export parameters into a user-defined function?

Thanks in advance,

Samantha.

If you have defined the signature of your UDF then the return value of the UDF must be assigned to the Export paramter of message mapping.

Basically import parametrs represents the inputs to be passed for that function(message mapping here)

and export represents the output of that function.

so in your case if you want toassign the value to Export parameter (ERROR_TEXT) in UDF catch block

assign the error returned to the ERROR_TEXT field

You can make use of this export parameter only in transformation step of Integration Process. You may use the following "Parameterized Mapping Programs"
