      During the hierarchy / attribute realignment run BW makes a decision about whether to adjust or rebuild aggregates based on the percentage of rows that require change. The threshold is set using RSCUSTV8.

      Possibly the same threshold applies in archiving? This could be tested by changing the parameter to 0 -- always reconstruct, or 99.
