SAP BW extractor F1 vs F2

[lakshminarasimhan_n4]

Hi All,

I am using both F1 and F2 interface for data extraction and both of them works the same way. In case of F1 once I change the value from F2 to F1 then i will not be able to modify the generic delta. Which is better ? Advantages and disadvantages of both? Is there any official release on the same?

Any updates available? I am comfortable in using the F2 interface(RSAX_BIW_GET_DATA_SIMPLE) but I need to justify on how it is better than RSAX_BIW_GET_DATA.

Please share me the advantages and disadvantages in both RSAX_BIW_GET_DATA and RSAX_BIW_GET_DATA_SIMPLE.
