Send IDocs

This section shows how to send an IDoc.
To configure your SAP system to send IDocs, see Set Up a Test Environment for IDocs.

There are two ways to create an IDoc object:

  • CreateIdoc creates an IDoc with all segments located in the segment collections.
    This is useful for sending simple IDocs.
  • CreateEmptyIdoc and CreateSegment create only the needed segments.

Send an IDoc

Follow the steps below to send IDocs:

  1. Connect to the SAP system using R3Connection.
  2. Use CreateIdoc or CreateEmptyIdoc to instance a valid IDoc object. Provide an object type for the IDocs, e.g., "SYSTAT01", "MATMAS01", "ORDERS01", etc.
  3. Provide receiver and sender information.
  4. Fill in the fields in the IDoc segments.
  5. Send the IDoc using Send.
  6. Run the program and check the result.

Tip

Use SAP transaction WE60 to look up the segment documentation of IDocs.

Note

Make sure to configure your SAP system to receive IDocs.

Output:

The status code of the manipulated IDoc increases from 3 (Data passed...) to 12 (Dispatch OK).
