In addition to the William’s blog:

Note: We need to maintain the NWA settings as mentioned in the blog

Once the settings are maintained most of the developers have issues while configuring the user module for IDoc flat to XML format conversion.

This blog mainly highlights about the steps & the IDoc flat file format should be for Inbound scenario.

The common issues which we can expect:


Error: (3) IDOC_ERROR_METADATA_UNAVAILABLE: The meta data for the IDoc type "ORDERS05" is unavailable."


      *This issue is because of the user doesn’t have necessary authorization which you have maintained while creating the destination to the backend system.
               Make sure that user has the authorization object*”S_IDOCDEFT”* assigned.



*Module Exception '' found, cause:               
           java.lang.NumberFormatException: For input string: ""

Most of us think we have an issue with the data. Right, I agree. Let's suppose we have a mapping we can suggest  formatNum function, but if we don’t have the mapping defined then still the issue persists. Based on the issue we all know that system is expecting value instead of null right.


      * The issue is with the IDoc flat file which we receive from the third-party, In general for inbound scenario we can’t expect the Document Number & complete control segment data from them…

Note:      If we use the same file for the inbound scenario as mentioned in the blog it works successfully but we don’t receive the file in the same format as same as mentioned in the blog.


For inbound scenario we can expect the control segment only with IDocType & MessageType data of that particular IDoc & for each Data segments there should segmentnumber & Parent Segment            number defined.   Sample file attached herewith…


I hope this will help you to understand more in detail about the file & the issues…
