Batch Data Communication

• BDC’s are interface are used to upload the data from legacy system to SAP System.

• 2 Methods.1. Call Transaction method.2. Session method.

• Steps :1. Get the flat file from the customer. Flat file might be excel or text

file.2. Get a sample recording with the help of SHDB . 3. Create a program with the help of recording.4. Create a structure according to flat file fields.5. Upload the flat file data into internal table using GUI_UPLOAD.6. Loop at internal table to work area to create to repeat the

operation.

• Sample record using SHDB.

• Click on new recording .• Enter recoding name ex: zmaterial.• Transaction code . Ex : MM01.• Update mode .• And click on start recording.
