File Adapter : Sequence Check

Posted on Oct 05, 2005 at 11:43 AM 19 Views

Hello,

I'm facing the following issue: We receive files from a trade parter. These files have a sequence number in their file name. Eg. utilmd001.txt. We need to send these files as idocs to our SAP system. But we can only process a file if the previous file is already processed. Eg. utilmd003.txt can only be processed if utilmd002.txt is processed. Any idea on how to incorporate this in the file/FTP Adapter? Also note that we cannot assume that utilmd002.txt arrives before utilmd003.txt.

Any ideas?

Greetings,

Bart

Hi Bart,
An option could be to store incoming messages on a intermediate folder, and have the file adapter of XI listening for incoming files at another folder where files are placed (by a custom written Java application or some FTP/Batch procedure..that keeps the sequence of received files in memory or a file) one by one in the correct sequence.
In this way you are always sure that XI only process those files in the correct sequence.
Cheers,
Roberto

  Hi Bart,
  
  I know it is possible to define generic modules (here is where the Java function comes into the picture) for each adapter in the module processor to enhance the adapter with additional functionality (e.g. SequenceCheck). I haven't tried before but you can always try. The FTP/batch commands alternative is a workaround that is simply and fast (without knowing your specific requirements) to implement.
  
  Check this link for more info on the module processor: http://help.sap.com/saphelp_nw04/helpdata/en/f4/8620c6b58c422c960c53f3ed71b432/frameset.htm
  
  And
  
  This one for more info related to the development of your own modules: http://help.sap.com/saphelp_nw04/helpdata/en/f4/8620c6b58c422c960c53f3ed71b432/frameset.htm
