KE5Z takes long time

Hello Gurus,

We have an issue. KE5Z report takes quite a long time to fetch the results. The porpblem is if I give the year as 2008 it would fetch the results in 7 secs. But for the same input parameters if i Give year as 2011 it takes 7 mins. I have checked the volume of data. For 2008 and 2011 , the volume is same. A small information , Data is not archived from PCA for the last 4 years.

Please give us your valid inputs.

Thanks
