Reg delta index and BIA index rebuild
BIA was recently implemented in my project and as part of the process chains, BIA roll up of new requests happens daily.
Also every weekend, we are doing a complete rebuild of BIA indexes for the cube with the understanding that the BIA roll up loads new data as delta indexes and hence Rebuild of BIA index is reqd to merge delta index with main index.
But when i checked from RSDDBIAMON2 ---> BI Accelerator --> index settings --> Set delta index, "I am finding that no checkbox is enabled for any of the indexes", which sounds to me that there is no delta index.... in which case, i am wondering what is the need to rebuild BIA indexes every week?
Can someone shed some light on how to confirm that there is delta index or not? and if there is no delta index and the roll up is actually writing data to main memory only, then weekly rebuilding BIA index is necessary?
