USIng BODS how to do delta using ECC Extractor

Hi All,

Hope you Folks doing well,

I have 2 question In sap bods as am new too SAp BODS.

1) How to do Delta in sap bods using ECC Extractor;

2) As i checked the many blogs for ECC extractor Delta and i found one things, by using CDC transform we can capture the new insert and update.

As in ECC Extractor we have two columns one For " SEQUENCINg THE ROWS" and Other one IS " OPERATION CODE"

But in extractor am getting only ( blank in "Operation code" and Sequencing row: only 0) Please inform me who going to update this 2 column in ECC extractor , Is it abab PPl or bods guys has to implemnt that just to get that proper "operation Code" and Sequence number in ECC Extractor.
