Rollup to aggregate performance

Hi all,

I have a trouble with rollup to aggregate. When I check the RSDDSTATAGGR table I can see 2 different scenarios for the same aggregate:

1. In case the RSDDSTATAGGR-CHANGEMODE = R(Rolling up data from the source cube into the aggregate) the rollup to aggregate takes about 1000 seconds.

2. In case the RSDDSTATAGGR-CHANGEMODE = D(Add from delta because of master data changes) the rollup takes about 15 000 seconds.

The aggregate contains an infoobject which is used as a navigation attribute in cube.

Setting in RSCUSTV8 transaction is Delta Limit = 20 %.

It seems to me really strange that the delta rollup takes so much time and more time than full load from cube?

Do you have any idea why?

Thanks a lot.
