Deltas not reflecting in the cube

Hi All,

I have some unique problem.

I have one Process chain which is doing Delta load from 6 different Data Source to 1 Cube .

This chain triggers 3 times perday.

My problem is even though delta request contains data, the same data is not getting updated in the cube after the data upload.

Its getting reflected in the cube only once in 3 days.

I really didnt understand whats the funda in this.

Can anyone of you guys please let me know how this working and where the process going wrong.

Regards,

Sheetal.
