[Former Member]

Hi,

What is the step-by-step procedure to create a outbound IDOC? Sample code and detailed explanation of each step will be very helpful as iam new to this topic.

Hi,

Floowing code used to create outbound Idoc sample code>....

Selection Screen

The selection screen in the stand-alone programs allows the user to specify the objects for which IDocs are to be generated. Although the selection screen has not been standardized because of varying needs of the application programs, the ALE programs for master distribution have some similarities. At a minimum they allow a user to select one or more objects, a receiving system, and the message to be generated. Refer to the selection screen for distributing the material master (Transaction BD10).

Program Flow

The program logic contains the following blocks:

1. Provide a selection screen to allow a user to specify the various objects for which IDocs are to be generated.

2. Determine the key of the application document from the object specified in step 1.

3. Select application data from the database using the object key identified in step 2.

4. Populate control record information.

5. Populate an internal table of type EDIDD with data records for the various segments.

6. Call the ALE service layer (MASTER_IDOC_DISTRIBUTE) to create the IDocs in the database.

7. Commit work.

The program in Listing 32-2 generates the monthly report IDoc ZMREPT01, which illustrates a stand-alone outbound process.
