SAP Netweaver 7.31 SP16 - dynamic configuration - Header Properties with variables defined and filled in a routing

[former_member720277]

Hi,

I use SAP Netweaver Process Integration 7.31 SP16 Java Only. My problem is to fill Header Properties with variables defined and filled in a routing mapping.

I know, this example isn't practicable for the dynamic Routing. It is only an example to show the problems in combination with dynamic routing, variables and adapter specific message properties.

What do I do step by step:

- Message Mapping defined.

- Operation Mapping defined

- Process Integration Szenario defined

- Process Integration Scenario defined

- Integration flow with dynamic routing defined.

- Receiver channel with file access parameters and adapter spezific message properties defined

- The test is faulty.

What is the problem? Is it generally possible to use the adapter specific message attributes by a receiver-split (Dynamic Routing)? Can anybody help me.

Thanks,

Angelika

Hi Angelika,

For both Directory and FileName you need to use separate UDFs.

For Directory UDF you need to return corresponding Directory parameter, and for FileName UDF you need to return the corresponding FileName parameter at the end.

Note that, per UDF, you need to take only one input string FileName or Directory as input respectively including container (ofcourse).

Reward points if helpful.

HI Angelika,

Can you check whether you have enabled the ASMA in sender channel, as in your udf, you have written code first by checking the dynamic configuration object should not be NULL.

Please enable it in the sender channel or else remove the line conf!=null in the udf code if you don't want the first part.

Hi,

I set the ASMA in the Sender channel. But the result is unfortunately the same.

Best regards,

Hi Angelika,

Please remove the IF condition line(only if(conf!=NULL) &  if-parenthesis) in the udf, and do the testing.

Kindly try this out and let me know the outcome.

Vishnu

[former_member720277]

Hi Vishnu,

I do it so. It is not the solution of the Problem.

Hi,

Please follow the latest reply which I gave and let me know.

Hi Angelika,

Can you please use the below udf and let me know if you still having issues.

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

DynamicConfigurationKey dck = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File",dynConfKey);

dc.put(dck,dynConfValue);

return dynConfValue;

Hi Souvik,

yes, the UDF-coding-test was successful.

Do you have still any idea?

Thanks in advance.

Angelika

[Former Member]

Hi,

The FileName is in .xml format, but the UDF returns String.

Try converting the FileName to .txt format and check if it works.

Regards,

[former_member720277]

Hi Vishnu,

I changed the UDF as desired, but I see no change whatsoever in the result.

Do you have any other idea.

Thanks and regards,

Angelika

[former_member720277]

Hi Souvik,

in the receiver channel is the transfer mode 'Text'.

In other respects I don't know, where I can define the transformation - maybe in the module.

Which module must I embedding.

Thanks in advance and regards,

Angelika

[Former Member]

Hi Angelika,

If the transfer mode is in Text, that simply means the file will be transferred in line by line mode

What I meant was in the mapping you have written IF060_.xml.

Kindly change that to text mode.

Souvik

Hi Angelika,

Can you please let me know why you are validating whether key exists for DynamicConfiguration or not in IF condition?

AFAIK, when we go for dynamicconfiguration mechanism, normally we don't put conditions for validation unless and until if it requires.

Can you just use the below code and check the outcome.

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

DynamicConfigurationKey dck = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File",dynConfKey);

dc.put(dck,dynConfValue);

return dynConfValue;

Please let me know if this doesn't cover your requirement.

Regards

Vishnu

[former_member720277]

Hi Vishnu,

I don't use a condition in the Integration Flow.

I already used the code. Please look at my answer today at 9:18 p.m.

Regards,

Angelika

[former_member720277]

Hi Souvik,

I changed the constant to .txt. But the test wasn't successful.

Angelika

Hi Angelika,

I checked your reply at 23rd, 8:19 AM one, where you said that you have changed the udf and still getting the error.

I can see in that udf, still you have used the below condition:

if(map.containsKey(StreamTransformationConstants.DYNAMIC_CONFIGURATION)

Hence, asking you to remove this line and its parenthesis and just use the below code and check the outcome.

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

DynamicConfigurationKey dck = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File",dynConfKey);

dc.put(dck,dynConfValue);

return dynConfValue;

The only difference in this udf code and your's is that I have removed the IF condition validation.

Please check this udf and let me know if you still having issues.

Hi Vishnu,

I changed the UDF.

and then I tested the message mapping. This is faulty.

Regards,

Angelika

[pvishnuvardan_reddy]

Hi Angelika,

We can not test the dynamic configuration object value in mapping level.

Please test end to end and check the outcome.

Regards

Vishnu

[former_member720277]

Hi Vishnu,

o.k., but the end to end-test is faulty, too.

Hi Angelika,

One quick thing I can point here is when receiver communication channel is FTP, it does not involve any mapping, since you will have only file as a whole object getting transferred.

However, since the mapping is essential for dynamic configuration setting, so please use SOAP adapter on the receiver side in order to configure your channel. Also if you refer the error log it says "SOAP_http://sap.com/xi/XI/System" as the end point on the receiver side.

So please use SOAP adapter on the receiver side.

Hope this resolves your problem now after such a lengthy discussion

Do you have the same message id even after the dynamic receiver determination?

if you don't have any mapping needs, just write a java mapping to set the dynamic filename as explained in below wiki.

Dynamic file name for pass-through scenario - Process Integration - SCN Wiki

[pvishnuvardan_reddy]

Hi Angelika,

I am not sure where it is going wrong.

Can you please try this, instead of using two graphical variables in the target side.

Directly Map the dynamic Filename mapping logic to the target node Receivers

Directly Map the dynamic Directory mapping logicto the target node Receiver

After doing this change, Test end to end and check the outcome.

Regards

Vishnu

[former_member720277]

Hi Souvik,

to change the adapter type isn't possible. I must use the adapter type file!

If I need the dynamical message variables in a 1:1-message mapping (not in a routing-mapping!!!) then the result is right.

Perhaps is it a bug in SAP-PI?

Regards,

Angelika

[former_member720277]

Hi Vishnu,

It isn't the solution.

Is it possible that it is a bug in SAP-PI?

Regards,

Angelika

[former_member720277]

Hi Hareesh,

thanks for your answer.

I am not a Java-developer - unfortunately.

I'd like only to know, whether I can use the dynamic configuration in a routing mapping and use the variables in the file-receiver-Adapter (ASMA).

Regards,

Angelika

[pvishnuvardan_reddy]

Hi Angelika,

To trace out the issue, can you please do the following things(this is applicable for PI single stack version):

Enable Receiver Determination(MS) and Mapping Step(AM) LOGGING in the ICO as below:

After doing the above change in the ICO, please do end to end testing. From Message monitoring DataBase tab, open the message and there you can see Message attributes tab, then if the dynamic configuration udf has executed successfully, then you see the filename and directory against the file namespace accordingly. From this, we can trace the issue.

Please try this and let me know the outcome with screen shots, which can help us to narrow down the root cause.

Regards

Vishnu

[former_member720277]

Hi Vishnu,

I set the logging parameters and test the scenario.

Is that instead an indicator, that it isn't possible to use dynamic configuration in a routing mapping?

Regards,

Angelika

[pvishnuvardan_reddy]

Hi Angelika,

From this, we can tell that dynamic configuration mechanism did not work in routing mapping.

Not sure, is this a bug in PI.

One final thing, I can tell you to check is that, remove the graphical variables in the target side, and

Directly Map the dynamic Filename mapping logic to the target node Receivers

Directly Map the dynamic Directory mapping logicto the target node Receiver

Please test end to end.

Regards

Vishnu

[former_member720277]

Hi Vishnu,

I did the changes, but it was the same result.

Regards,

Angelika

[pvishnuvardan_reddy]

Hi Angelika

No, what i mean is that remove the graphical variables(Dateiname,Verzeichnis) that you have defined at the target structure in the mapping. And do the mappings of filename logic and directory logic as below:

Map the dynamic Filename mapping logic to the target node Receivers

Map the dynamic Directory mapping logicto the target node Receiver

Can you try this and test end to end.

Regards

Vishnu

Hi Vishnu,

Your target structure in mapping is getting the FileName and DirectoryName, but the receiver channel is not able to detect the FileName. You can use Variable Substitution in Receiver FTP channel in Processing tab, but the Directory Name issue will be the next problem

Small mouth, big words from my end, but I feel its a small bug in PI if such a scenario is used.

Souvik

[former_member720277]

Hi Souvik,

thank you for your support.

I have the same meaning, its perhaps a bug in PI.

I will open a notice by SAP.

Regards,

Angelika

[pvishnuvardan_reddy]

Hi Angelika,

If you are okay to try for one final time, then please check as below:

1. I have added trace in the udf code, in this way, we can come to know whether our udf is executing or not in the runtime. Try the below udf  in ESR.

AbstractTrace at = container.getTrace();

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

DynamicConfigurationKey dck = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File",dynConfKey);

at.addInfo("Before putting dynamic" + dynConfKey + "with Value" + dynConfValue);

dc.put(dck,dynConfValue);

at.addInfo("After putting dynamic" + dynConfKey + "with Value" + dynConfValue);

return dynConfValue;

2. I would say to recreate the ICO once again, deleting the existing one...

Not sure, whether this resolves the issue or not, but I could say worth a try...

Vishnu

[former_member720277]

Hi Vishnu,

Should I open a SAP-notice?

What do you mean? Is it a bug in PI?

Regards,

Angelika

[pvishnuvardan_reddy]

Hi Angelika,

Then it might be a bug in PI.

Can you check the message log, whether the trace which we added is coming in the log or not, from this we can come to know, our udf executed or not..

If you need to handle this in routing mapping itself, then go ahead with OSS message to SAP.

Since it is a pass through scenario, can you create a interface mapping having the same structures on both ends, and handle the dynamic configuration in message mapping...

Regards

Vishnu

[former_member720277]

Hi Vishnu,

a trace isn't coming in the message log.

I go ahead with OSS message to SAP.

I have the scenarion already developed as a pass through scenario and this works fine.

Thanks a lot again for your Support.

Angelika

Hi,

It seems all the settings are correct. Just move the FileName in the target Message Type above Directory, i.e., FileName should come before Directory.

Reason being in ASMA setting it checks the FileName first.

Souvik

[former_member720277]

Hi Souvik,

thank you for your Support.

But it isn't the solution for this Problem. The bug is still existing.

Please enable it in the sender channel or else remove the line conf!=null in the udf code if you don't want the first part.

Regards

Vishnu

[former_member720277]

Hi,

thank you for your answer.

I set the ASMA in the receiver channel and I filled the variables in the routing mapping.

I don't understand, why I should set the ASMA in the sender channel?

I think the sender ASMA aren't important or is it wrong?

Best regards,

Anelika

[pvishnuvardan_reddy]

Hi Angelika,

In you udf, you have written code first by checking the dynamic configuration object should not be NULL.

Hence I am asking you to enable the ASMA setting in the sender channel.

If you don't want to do this, then please remove the IF condition line(only if(conf!=NULL) &  if-parenthesis) in the udf, and do the testing.

Let me know if you still facing issues.

Vishnu
