generic delta extraction

Hi all,

I made a generic extractor based on view with 8 tables, which 2 tables custom and 6 standard.

I have setting Timestamp and ZDATE field from custom table as point of delta determination, with upper limit 1800 seconds and lower limit empty

The ODS is empty, then I loaded the init infopackage without transfer data and then there is the record into RSA7 delta queue but the LUW is 0.

How can I do, please?

Thanks in advance
