Mapping Exception during Dynamic file configuration

[Former Member]

Hello,

I have to configure the file adapter such that the file name is configured dynamically.

I wrote a UDF which gives the following error.

<SAP:Stack>com.sap.aii.utilxi.misc.api.BaseRuntimeException thrown during application mapping com/sap/xi/tf/_GSFt_AccountReconciliation_Format__{: RuntimeException in Message-Mapping transformatio}</SAP:Stack>

<SAP:Retry>M</SAP:Retry>

</SAP:Error>

The code is :

DynamicConfiguration conf = (DynamicConfiguration)

container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

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

String FileName = conf.get(key);

String newFN = FileName.substring (11,15) ;

String FN = "<abc>+ newFN + "_" + ".dat";

conf.put(key,FN);

return FN;

Am I missing something here?

I have also specified the variable substitution in Receiver Channel.

Kindly help me out ppl.

Regards,

Sanjay

Modify code as below...

String FN="";

try{

DynamicConfiguration conf = (DynamicConfiguration)

container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

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

String FileName = conf.get(key);

if(FileName != null && FileName !=""){

String newFN = FileName.substring (11,15) ; //make sure u do substring rite way... index 10 is 11th char of the string

FN = "<abc>+ newFN + "_" + ".dat";

conf.put(key,FN);

}catch{

}

return FN;

Hi,

When it is taking substring, it is really surprising to see that it is taking a value from the Target Filename

instead of the source.

How can this happen?

Am I missing something in the code or configuration part?

I have enabled ASMA for both adapters.

How should I name the file scheme in ID. I have done that also in a proper way.

Following will fail if you do not process this via file adapter:

String FileName = conf.get(key);

String newFN = FileName.substring (11,15) ;

because FileName then is null and you will get a null pointer exception. So better check for null:

if (FileName != null) {

....

}

I have also specified the variable substitution in Receiver Channel.

This is wrong.

Enable ASMA in Sender and receiver channels and check on File Name

Hi,

Check in mapping trace for more detials on mapping error.

Hi Sanjay,

The Dynamic configuration code seems to be fine but a small change. Test with the below code because the syntax is wrong in your code.

Use the below code"

DynamicConfiguration conf = (DynamicConfiguration)

container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

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

String newFN = FileName.substring (11,15) ; 

String FN = "<abc>" + newFN + "_" + ".dat";

conf.put(key,FN);

return FN;

Thanks,

Hi Hareen,

I checked my UDF and I made a mistake while copying it here. UDF looks fine. and I think if there is a syntax error,

It doesn't get activated.

But mine got activated.

Hi,

Did you enabled Adapter specific message attributes in sender adapter?

Hi,

In addition to the above suggestion, please chk ur code syntax:

Should be like this:

String FN = "<abc>" + newFN + "_" + ".dat";

Thanks

Are you testing this in message mapping or are you doing an end to end testing?

hi shabz,

I did an end - to - end testing.

But still ..

Have got a silly doubt. But in your blog, I got a bit confused.

If we use dynamic config, is it necessary to use the Variable substitution?

I am not clear on this.

let me know.

[former_member200962]

If we use dynamic config, is it necessary to use the Variable substitution?

No...use only ASMA...dynamic config.....not variable substitution.

[Shabarish_Nair]

dynamic configuration is an alternative to variable substitution.

So you dont have to use both together.

Have Mapped the root nodes.

Is there any chance that my UDF is wrongly mapped to element.

I have mapped it with the root nodes.

[aashish_sinha]

Hi,

I hope you following below steps

- Create an UDF and include the piece of code that captures the Filename and Timestamp from source side via ASMA.

- Map the UDF to any of the top level node so that the modified filename will be available for the target communication channel

test mapping also from test tab in Message mapping

Hi Sanjay,

There are many solutions to set target filename.
