Data visible in PSA but not in DSO

Hi All,

I've enhance a LO extractor with a KF and the values for this KF is visible in PSA but when I run the DTP to load to DSO the values of this KF is dipalyed as 0.

Note in PSA there are 4 records and they should be summed up and displayed.

I've set the rule to summation.(tried with overwrite also but didnt work)

Please suggest.

Thanks

Madhavi
