This document describes two methods for uploading batch data from a legacy system to SAP: the call transaction method and session method. It provides steps for both methods, which include getting a flat file, creating a program recording, defining a data structure, uploading the data, and executing transactions via BDC calls or a session. The document also describes using LSMW for legacy system migration, with steps like creating a project, recording transactions, defining source structures and fields, and relating structures.

1. Batch Data
Communication

2. • 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.

3. • Sample record using SHDB.

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

7. Call Transaction Method
