ALE (Application Linking and Enabling )

ALE is technology for SAP mainly use to transfer data between SAP systems.

A means of creating and operating distributed applications.

Application Link Enabling (ALE) guarantees a distributed, but integrated, R/3 installation. This involves business-controlled message exchange using consistent data across loosely linked SAP applications.

Applications are integrated using synchronous and asynchronous communication - not by using a central database.

ALE consists of the following layers:

Application services

Distribution services

Communication services

BDC

The batch input program must build all of the input to execute the SAP transaction.

Two main steps are required:

• To build an internal table containing every screen and every field to be filled in during the execution of an SAP transaction.

• To pass the table to SAP for processing.

Prerequisite for Data Transfer Program

Writing a Data Transfer Program involves following prerequisites:

Analyzing data from local file

Analyzing transaction

Analyzing transaction involves following steps:

• The transaction code, if you do not already know it.

• Which fields require input i.e., mandatory.

• Which fields can you allow to default to standard values.

• The names, types, and lengths of the fields that are used by a transaction.

• Screen number and Name of module pool program behind a particular transaction.

To analyze a transaction::

• Start the transaction by menu or by entering the transaction code in the command box.

(You can determine the transaction name by choosing System – Status.)

• Step through the transaction, entering the data will be required for processing your batch input data.

• On each screen, note the program name and screen (dynpro) number.

(dynpro = dyn + pro. Dyn = screen, pro = number)

• Display these by choosing System – Status. The relevant fields are Program (dynpro) and Dynpro number. If pop-up windows occur during execution, you can get the program name and screen number by pressing F1 on any field or button on the screen.

The technical info pop-up shows not only the field information but also the program and screen.

• For each field, check box, and radio button on each screen, press F1 (help) and then choose Technical Info.

Note the following information:

The field name for batch input, which you’ll find in its own box.

The length and data type of the field. You can display this information by double clicking on the Data Element field.

• Find out the identification code for each function (button or menu) that you must execute to process the batch-input data (or to go to new screen).

Place the cursor on the button or menu entry while holding down the left mouse button. Then press F1.

In the pop-up window that follows, choose Technical info and note the code that is shown in the Function field.

You can also run any function that is assigned to a function key by way of the function key number. To display the list of available function keys, click on the right mouse button. Note the key number that is assigned to the functions you want to run.

Once you have program name, screen number, field name (screen field name), you can start writing.

DATA TRANSFER program.
