Hi Mukesh,

Go through this to know about the ALE

I hope this is helpful to you,if so please reward me.

Thanks,

You need to take the date in an internal table

and pass that internal tabel to function module

'MASTER_IDOC_DISTRIBUTE'

see the code

and ask if doubt

ALE: CREATING AND USING NEW IDOC TYPES

SAP supplies maximal IDoc types for master data. We can create our own reduced IDoc types, by selecting only those segments and fields which are relevant to a specific project. We can also create extended IDoc types, by appending one or more segments to an existing IDoc type. In both cases, we use a standard SAP IDoc type as a template for the reduction or extension. As an alternative, R/3 allows the customers to create their own IDoc types, from scratch. This alternative method is the topic of this article.

In our simplified scenario, an ABAP program on the sending system reads a message and a one-character key entered by the user. The program adds the user name, the current date and time, and sends the information to the receiving system. The receiving system processes the data and posts it to the database. It also sets the appropriate status of the IDoc, which then can be checked in the IDoc List (WE05).

In order to achieve our task, the following steps are necessary:

1. Create data container (Idoc)

2. Create database table

3. Create outbound program

4. Create inbound function

5. Set up ALE customizing

6. Send data

Step 1: Creating a new IDoc

• Create new segments

Segments are field strings that contain grouped data of the message. The name of the segment type must start with Z1. For each field in the segment, define a field name, a data element for the segment structure, and a data element for the segment documentation. The system will create three structures:

Z1xxxxx - field names

Z2xxxxx - data elements for structure definitions

Z3xxxxx - data elements for documentation

To create a new segment: in the ALE IMG, select Extensions->Idoc types->Maintain IDoc type (transaction WE31); Goto->Maintain segment. Enter the segment name and description, and click on Create. After entering the segment fields, save and activate your segment. This should be done for each new segment in your IDoc (in our case we have one segment).

• Create new IDoc type

The IDoc type describes the technical structure of a message. It defines which segments will be used, and what is the hierarchical structure of the segments. For each segment, it also specifies whether it's mandatory or optional, and how many times the segment may appear in the IDoc.

To create a new IDoc type: WE30, select "Basic IDoc type", enter the name, and click on Create. Add segments to the new IDoc type (menu Segment->Create).

• Create new message type

The message type describes the contents of the message. It helps the system to decide how to process the message. To create a new message type: WE30, Environment->Message types; Display->Change; New entries. Enter the message type name and description.

• Link message type with IDoc type

ALE IMG->Extensions->IDoc types->Maintain message type for intermed. structure; choose "EDI: Message types and assignment to IDoc types"; Display->Change; New entries. Enter the Message type, the BasIDoc type, and the release. Your link will not be valid for prior releases.

Step 2: Create a new database table

Go to the ABAP/4 Dictionary Initial screen (SE11), and create a new table. The table should mirror the structure of the segment created above.

Step 3: Create a program for outbound processing

Fill data into Idoc and pass IDoc to ALE layer. Close LUW (commit work). The IDoc consists of a control record and one or more data records (segments). The data segments contain the data of the message. They are passed to ALE as an internal table (structure EDIDD). The control record contains general information about the IDoc (structure EDIDC). Function MASTER_IDOC_DISTRIBUTE is called to pass the IDoc to ALE. For further details, see the code in Appendix A.

Step 4: Inbound processing

Create a function module for the inbound processing. Check that the IDoc contains the correct message type. Convert the character data to internal format, if necessary. If the data is OK, post it to the database table. Otherwise, return an error message to ALE. For further details, see the code in Appendix B.

a) Allocate API to Message Type

ALE IMG->Extensions->Inbound->Allocate function module to logical message; New entries

Module name of your function

Type 'F' (function module)

BasicIDoc type you created in step 1

Message type you created in step 1

Direction '2' (inbound)

b) Declare API Attributes

ALE IMG->Extensions->Inbound->Define settings for input modules; New entries

Function module name of your function

Input t. '1' (individual input)

Dialog alllowed ' '

c) Maintain Inbound Process Code

ALE Extensions->Inbound->Maintaining process codes (inbound); select "Inbound with ALE service" ->"Processing by function module"; Create;

New entries

Identification name of your function

Step 5: Set up ALE customizing

In the distribution model, you have to define which messages are distributed from one system to another. The model directly controls the distribution. ALE IMG->Distribution customer model->Maintain customer distribution model directly; Maintain message flow. We assume that the communication parameters, like partner profiles, ports, RFC destinations, have been set up by this time. You can run a consistency check for your set up.

Step : Send data

On the sending system, run the program created in Step 3. The data will be put into an IDoc and sent to the receiving system. On the receiving system, use the IDoc overview (WE05) to check that your IDoc has arrived. If it has been processed successfully, the database table created in Step 2 must contain the new record.
