Some transformation processes need IDoc type information. For example,
the outbound IDoc is received as plain text. The subsequent transformation
process must interpret the plain text. The generation process calls the Rpc2Rfc
function IDOCTYPE_READ_COMPLETE. The transformation process in the
pipelines needs the IDoc type
information. To generate the specific IDoc type information, go to the
development IDoc Type page of IDoc XML Gateway or to
http://YourGateway:8080/sapr3idocxmlgateway/transformer/IDocType_ToFile
The first table shows the Available IDoc Types that have already been successfully generated by SAP R/3. The button will delete the corresponding type. The button generates the webMethods EntireX interface definition in a new window.
To start the generation process, you must set the fields in the Generate IDoc Type Information dialog:
| Field | Default | Description |
|---|---|---|
| IDoc Type | None | Enter the IDoc type name. |
| R/3 Client | None. See Rpc2Rfc parameter Gateway Logon Strategy | Connect with R/3 client. |
| R/3 User ID | None. See Rpc2Rfc parameter Gateway Logon Strategy | Connect with R/3 user ID. |
| R/3 Password | None. See Rpc2Rfc parameter Gateway Logon Strategy | Connect with R/3 password. |
| Broker | localhost with default port 1971 | IP connection parameter |
| Service | RPC/R3RFCD/CALLNAT | Name of broker service |
The generation process waits until all data have been retrieved from the SAP application server. The next page will show an update of available IDoc types or the System Log, if an error occurs. In this case, the first two lines will show the error message.
Tip:
Type information contains many comments on the groups and fields. The
comments are language dependent. You can change the language parameter on the
Rpc2Rfc kernel to get the comments for
your language.
Important:
Pipeline processing
stops if an IDoc type is missing. If this happens, generate the IDoc type and
restart the pipeline step for transformation for processing to
continue.
The IDoc types in the file system work for the transformation step as a
cache. It is possible to change the default handling and to get the IDoc type
for each transformation step at runtime from the SAP R/3 system. Note however,
that this requires considerable resources and will have an effect on
performance. To change the default file cache handling, edit the
IDocType.xsl stylesheet. Change the documented
xsl:import statement.
