IDOC XML/SOAP Structure is Reversed After Import

Problem

Due to an issue with the importer that mixes segment type with segment name for IDOC, the imported XML/SOAP is reversed.

Example:

Assumed we have an IDOC Parser file containing a snippet like this:

CODE

    BEGIN_GROUP                    1
      LEVEL               02
      STATUS              OPTIONAL
      LOOPMIN             0000000001
      LOOPMAX             0999999999
      BEGIN_SEGMENT       E2BPE1MARAEXTRT000
        SEGMENTTYPE         E1BPE1MARAEXTRT
        LEVEL               02
        STATUS              MANDATORY
        LOOPMIN             0000000001
        LOOPMAX             0000000001
        BEGIN_FIELDS
          [...]  
        END_FIELDS
      END_SEGMENT
      BEGIN_SEGMENT       E2BPE1MARAEXTRT1000
        SEGMENTTYPE         E1BPE1MARAEXTRT1
        LEVEL               03
        STATUS              OPTIONAL
        LOOPMIN             0000000001
        LOOPMAX             0000000001
        BEGIN_FIELDS
          [...]
        END_FIELDS
      END_SEGMENT
    END_GROUP

There are 2 segments defined:

E2BPE1MARAEXTRT000

of type E1BPE1MARAEXTRT and

E2BPE1MARAEXTRT1000

of type E1BPE1MARAEXTRT1 .

The importer will however create two types E2BPE1MARAEXTRT000 and E2BPE1MARAEXTRT1000 . The field names in the generated structures are correct and correspond to the segment names. There's however an External Name set for them which corresponds to the segment types.

This causes the XML/SOAP structure to basically be reversed.

Solution

There is no solution to this problem for the time being, and this will not be fixed anytime soon.

RFC Call Returns "field not found"

Problem

An RFC call to a SAP system returns no values, but an error message, e.g.

SAP error (Key: "RFC_INVALID_PARAMETER" Message "field 'EDI_DOCNUM' not found") occurred during request "INBOUND_IDOCS_FOR_TID...

This problem concerns only certain RFC calls like e.g. INBOUND_IDOCS_FOR_TID. For this call, the SAP system does not return any parameter names, but simply all values in an array.

Solution

Runtime 2020.13 The only way to access the parameter value is via its offset in the parameter table. You can specify the offset of the parameter as an external name on the parameter to point the xUML Runtime to the correct value.

Use 0 for the first element.
