Access the filename using Adapter Specific Message Attributes

http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/content.htm

Now u can compare this name with the payload value in graphical mapping itself

But i dont want to do mapping if validation fails. So i wanna check that before calling mapping step.

To comapre the File name you will write the UDF in that raise the exception if it is not equals. I hope the mapping won't processed if exception is raised.

Warm Regards,

Hi,

I hope your scenario can be done like this.

Have a Integeration Process in ur scenario and receive the xml file in the IP.

Inside the switch u check for the condition i.e filename = source field if true then have the transformation step in one branch to do mappping and if false do nothing or raise an alert and just have a send step.

receive -

---

> switch(transformation/no process) -

---

> send

thank you for the reply vijay. But is it possible to do the same at receiver determination or some step before mapping

I think you can do this by using the Context objects.

First get the Filename into your dummy element in target strcutre using UDF and create the context object between your dummy element and another element which holds the filename with equal conditon and use this context object in the receiver determination.

But I am not sure about it because i never tried this.

<b>UDF as follows:</b>
 DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

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

DynamicConfigurationKey key1 = DynamicConfigurationKey.create(
"http://sap.com/xi/XI/System/File",
"Directory");

String source = conf.get(key);
String tar_dirname = "/mqm/mqmprod/temp/out/ " + source.substring(14,18); */

String tar_fname =source.substring(19,20);
String tar_dirname = source.substring(14,18);

conf.put(key, tar_fname);
conf.put(key1, tar_dirname); 

return tar_fname;

Warm Regards,

U can use the conditional receiver determination based on the value of the field. But then i dont think u can access the filename there.

In my opinion, mapping would be the only place to access both payload and the filename.

Workaround: U may try writing a module for the same

Yes....you can do this with UDF provided by the above or else you can validate your filename by writing the Adapter Module.

thanks for your reply. Is there any blog or something that guides on how to write such an adapter module

Hi,

Did u tried out this scenario using the switch step in BPM.
