error in mappingwith dynamic configuration using udf

[Former Member]

Hi All,

Good Morning,

i am working with ABAP proxy to file scenarion but here according my client requirement i am using udf for file dynamic configuration.

In mapping, i mapped the field from "Filename" to message type tag(receiver file header) "/ns0:MTxxxxxxDataFile". between there two fields i am using the following udf for dynamic configuration. but i got error after testing with test data in mapping that is also mentioned below.

plz help me to solve the error. i will be wait for ur immediate response this sis very urgent.

very thankfull to immediate response.

UDF:

i am not puting any packages here.

public String putFileNameInHeader1(String a,Container container){

//write your code here

DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");

conf.put(key, a);

return "";

}

Hi Sai,

First of all, this UDF is pretty well knaown so there is no error in this UDF or your configuration for this UDF. I can suggest you something that at the time of configuration in IR, give a context object for that particular field of that file and then use the contect object name everywhere to refer that field. and also check the message type config for correction for my sake.

There is also a possibility that of the input data. i guess you are sending the input file from Cognos and you making the file and putting some where in XI directory and want these to process something and generate with some new desired filename. Check the input because i guess its finding NOTHINg as an Input. check once again.

Hope this will help you.

Regards
