PROCEDURE TO WRITE A DATA TRANSFER PROGRAM :
1. Analyze the structure of the existing data and specify the
conversions that are required to fill the SAP data structures.
2. Generate the SAP data structure
If the program is written in ABAP, you need only include e required
tables in your program with the TABLES statement.
3. Initialize the SAP data structure.
4. Fill the structure with data, performing any conversions and error-
checking that are required.
5. Write the sequential file that is typically required for making the
data available to the batch input program in the SAP System.
THE PURPOSE OF ANALYZING DATA IS :
- To gather the transaction code that is to used
- List of the required fields for input
- Field names, types and lengths
- To note the screen numbers involved & program names for
the screen.
There are two ways by which you can achieve the above,
1. Go to System => Status
Run the transaction and note the information of Screen No. &
Program name
2. Place the cursor in the field and press Fl for Technical Information
of the fields.
