ssas incremental update

  • hi all,

    is there any way to incremental prosess cube ???

    exp : only 2010-10values delete and insert again new values 2010-10

    thanks

  • You can create Cube partitions and partition them by months. So if you need to delete for 10-2010 then you can delete that partition. You will again need to perform you ETL to load this portion of data and the create a new partition (possibly, but just confirm it with some other reference material).

  • You cant delete data out of the SSAS database, it has to be done at the Datasource (data warehouse) level.

    You can incrementally process a cube, though it can often be quicker just to process the entire thing, it depends on the amount of data that you have.

  • You can definitely delete data out of an ssas db, or more accurately, a cube in that db. This is what the processing option of clear data is for. Plus as already mentioned above, you can reload a single specific partition or even delete a partition.

  • It should be noted that the use of partitions for incremental processing is only available in the Enterprise and Developer versions. This will not be possible in Standard.

  • Be mindful of what the incremental update does during processing. You can load duplicates into your cube or partition if you are not careful. the incremental does not remove data it only adds to the cube. It's best used when your dsv or partition captures NEW data that needs to be loaded into your cube.
