Hi Srinu,

Depending on the flat file structure and the transaction which u r processing you can decide which method to go for. Actually it is decided by the Team lead or more high level members of the project itself.

Just you need to develop the program...

the fact is it all depends on your requirement and the decision taken by your client as well as the functional consultant,you r not the decesion maker bcz you dont know what is the amout of data you r going to get to upload,after they people taken the decision you only work accordingly.

Yes you are not the person(as a developer) who will decide the size/volume of the data. It will be done by Functional experts / SMEs.

If required you can give an option on the selection screen that will allow user to execute the program, and choose from batch session or call transaction.

Actually the conversion is to transfer data from a non-SAP system(legacy system) to SAP system.There r two types of BDC

1.Call Transaction

2.Session

In call transaction the session is automatically released whereas in session we need to externally release the session .

Call Transaction is for small amount of data and Session is for huge data.

The volume of data depends on the data that u need to transfer.

hi.it depends on the data that will be there in the flat file(notepad,excel).and based on that you can decide whether to use call transaction or session.
