Hello All, In rare cases, I saw some strange behaviour in the execution plan. What I believe is that it distributes the cost among the sub processes taking 100% as a whole. But at times I see the total cost exceeding 100% (at this tme 101%). I checked some sites and they state is a bug. Not that it affects anything and then also help resolve issues but was just curious to know if anyone has any updates on this ?

Could it be a rounding error?

Neeraj, I already checked that link but since it was old (probably in 2009 or 2010, so wanted to know if anyone has any update on that. Gail just confirmed that.
