Missing node in SAP response message - was set on request RRS feed

  • Question

  • Hi everyone,

    I have a workflow with a SAP send / receive port. Within this port I used to call a BAPI with a schema generated in Visual Studio (so all normal I guess). I have several request nodes that represent a table parameter in SAP. I'm passing all of them with the same syntax: <rfc:MYNODE />

    Now all nodes are filled when returned but one node is left blank.

    When I execute the BAPI directly in SAP the tables parameter returns 11 values.

    One line of this parameter would look like this:


    4711 | * | My text line with information


    Does anyone have an idea?


    Kind regards

  • Have seen a similar case that was caused by SE37 converting any invalid numeric value to 0. I'd like to suggest you capture netmon traces to determine if the returned data back from SAP has been Null or blank yet.

  • Just an idea...

    Ensure that “GenerateFlatFileCompatible” is set to true

    Thanks, Raja

  • Yes, the data received from SAP is already blank. Well not completly but the Tables-Parameter I mentioned above is empty. All others are filled with valid data.

  • I usw a RFC connection. But nevertheless I tried your suggestions - problem is still the same.

  • Well, after 2 hours of analysing Netmon Traces - there is no data send from SAP to BizTalk for the missing node.

    BTW: Is there a way of searching for strings in the data blocks of the network packages? I had to look by "hand" now.


    But if I call the function from another SAP, it returns all wanted data - if I call it from J2EE stack as well.

    Only BizTalk seem to cause this problem.


    Any idea?

  • You might want to enable RfcSdkTrace in the connection uri and look into the traces

    I presume that for the same input, you are getting expected response when called from sapgui. Do you see discrepancy only in this table field? Is there any other difference between the one you receive in Sapgui and BizTalk adapter?

  • Only in this field. All others are transmitted correctly. I tried with USE_SAPGUI = 1 and = 0, and I added the needed Registry settings for fill SAPGUI usage (SAPHTTP and SAPFTP won't work if not set). Both without any result.

    Changed TABLES structure in SAP, activated again. Regenerated schemas - seems to be fine (node names etc.) but still won't work.

    RFC traces states 0 entries, BizTalk logging as well. But it seems that it's only when BizTalk is calling via RFC. I don't really get it.
