Mapping question - File to Webservice scenario

[Former Member]

Hi

I have a text file - that is pulled in by XI - using a ftp adapter - source interface. On the other side - target interface - we have a webservice whose definition is loaded into XI as a external interface defiinition - message type level.

Now , for every record in the text file - I need to call the webservice method- once . The webservice method definition is such that - the top level node has occurence 1-1 and type is blank - The parameters to be passed to the method appear under it -

I tried using split-by-value node function to make the mapping call the webservice method once for each record in my input text file - this results in the webservice method being called just once - not as I expected ( once for each record in my text file )

Where am I going wrong with this ? Is it possible to make the call to the webservice method - with the top level node having the definition described above - once for each record in my source text file ? Since the webservice method has been imported as an external definition ( *wsdl ) , I am unable to put it under any other higher level element .

Any pointers/suggestions as to where I am going wrong - how to make this scenario work will rewarded with full points.

Thanks.

Hi,

Please go to Messages tab in message mapping and change occurance for external definition to 0..unbounded.

Thanks,

You would need multimapping for this. take a look at this blog for the same.

Hi Bhavesh

Thanks for the reply. We do not have an option of changing the webservice definition -

Also, unfortunately, I am on SP13 - I guess I have use BPM to do multi-mapping , right ? Could you forward any links - that illustrate - use of multi-mappings with BPM - through an example ?

Thanks.

Hi Karthik,

You do not need to change the web service definition. In the mapping change the occurance of the target message, to 0 to Unbounded.

In the BPM, once the multimapping transformation is done, you can use either a block or a loop step to send the messages. You would also need a container to collect the N messages and send them one by one or parallely.

Hi,

The multimapping with enhanced interface determination will work only from SP14. Yes are you said you would need to go for multimapping with BPM.

Also confirm me this if you are using a file with content conversion you have another option of setting Recordset per message = 1. If you set it to 1 it will create N messages so you can achieve the same without BPM or multimapping.

Thanks for the reply. Yes, I have a file content conversion - involved here - I have already specified the value for No.of Recordsets per message as<b> 1</b>.

However, I have specified the value for Recordset Structure as <b>TrkfileRecordset,*</b> - where TrkfileRecordset is my unbounded structure representing each line /record in my file .

With this setting, the whole file is being converted to a single xml message - with the records in the file repeating as multiple TrkfileRecorset nodes. Maybe , if I change the * to a 1 in the Recordset Structure definition - the file adapter will read each file record as a single individual message - as per your suggestion of avoiding a BPM.

Now, the typical volume we expect is 500 lines split across many file during a day - I am thinking - with this volume -whether involving a BPM ( which takes in one message per file and splits it ) or creating one xml message per record in the file ( which would mean 500 xml msgs per day ) would be better -

Please share your thoughts on the options I have with XI SP13 to handle this scenario.

Hi,

If you are able to split messge in the content conversion then that would be the best option from performance point of view rather than going for a BPM.

And also check the possibiltes of upgrading the SP to atleast SP14 so that you have lots of options like Adapter-specific messages, Enhanced interface determination etc..

Thanks for sharing your thoughts - I will change settings in file adapters to make each record in the file come into XI as a message - this is going to increase the number of very small msgs processed by XI - but I think this is better than bringing in a BPM into the picture . We are planning to move out of SP13 to SP14 or SP15 very soon.
