Pros and Cons of using different uploads in LSMW

Hi,

I need to prepare a document, which specifies the pros and cons of migration using LSMW by different methods for a specific upload, where all the below options are available.

1) Batch Input

2) Direct Input

3) Idocs

4) BAPI

If anyone has prepared any document, can you pls send to me at write2ananth@gmail.com or give me some pointers.

Thanks in advance,

Ananth
