Hi Karthik,
Well, if you are doing 1000 steps to do realignment in a info cube then you will see multiple APO requests in the cube. In this case, all of the source record exists in the cube.
In your case, please check how many records you are trying to do realignment step then how many of them successful. In Info cube apo request, check how many records it added to the cube.
Hope it helps.
