Data not getting exported through Export integration interface

I have a strange problem, created a simple editable series, entered some data from the worksheet and used it to export integration interface.

For the first time when I ran the integration interface WF data are populated in BIEO tables as expected.

But after that the data is not getting populated, integration interface setup looks fine data are available for the time period mentioned in the profile.

Created a new integration interface and tried exporting data it didnt work.

Did anyone of you faced similar sort of issue earlier? Any points will help.

Thanks
