Dense dimension behaving as sparse in PBCS?

Hi all,

I've experienced a strange behavior in a PBCS application where sometimes a dense dimension seemingly behaves as a sparse one —in the meaning that some calculations don't produce any output in empty cells unless a value is manually inserted in that cell previously.

This application only singularity is that it has 3 dense dimensions (Account, Period, and ContractYear).

Here's an example:

I'm expecting cell C13 to get the same value as C9 (so Initial_Cont_Date = Start_Date)

Now look at this piece of code:

SET CACHE HIGH;

SET CALCPARALLEL 8;

SET CALCTASKDIMS 2;

SET MSG DETAIL;

SET LOCKBLOCK HIGH;
