Urgent-Issue in the Dimension tables

Question

Hi Experts,
Question1:
I have a flat file load to a cube.this flat file has 1.5 mil records.One of the dimension created has a 2 dates(original date & current date) assigned.
When i look at dimension table for # entries is 30million.And when i look at the table i see the sids as 0,0 ( for 2 dates) and dim id's being creted.
When i did a search on the dimension table with current date & original date as not equal to 0.I see only 76,000 records.
Question 2:
we have an ODS which loads to the cube.In the process chain we have program that deletes the data in ods which does not match some conditions and then loads it tot he cube.
My question is,since we are not deleting contents from the cube and reloading it from the ODS(Full update).Will i not be seeing same records coming in with Full update which get agrregated in the cube.
Ex: i have a record in ODS.
A   X  Z  100  1000
After full update to the cube,the cube would have
A   X  Z  100  1000
When i run the process chain and data is dleeted from ODS on some condition and i still have hte same record in ODS and when this loads into cube wont this be aggregated with the previous record.
A  X   Z  200  2000
Would appreciate,if anyone could explain if i am missing anything.

Hello,
If you can't see the SID means you have not loaded the master data, that why there is no reference to the SID table and the values are 0.
InfoCube by default will have aggregated values, when there are duplicate records on the Keyfigures will be aggregated.
For example I have a Material Dimension and Customer Dimension
In the fact table,  it will be like this
DIM1     DIM2    KF1   KF2
Mat001  Cust1  100    10
Mat001  Cust2  200    5
for this there will be 1 entry in Material DIM table for Mat001 and 2 entries for Customer DIM table for Customer Cust1 and Cust2.
Material  Dimension
DIM ID    SID
1             Mat001  (Here it will be SID from Material Master)
Customer Dimension
1             Cust1  (Here it will be SID from Customer Master)
2             Cust2  (Here it will be SID from Customer Master)
Note : DIM ID is the combination of one or more SID in the dimension table.
So the exact fact table will look like
MATDIM    CUSDIM       AMT      QTY
1               1                  100        10
1               2                  200        5
If you load the data again with same characteristics values then the key figure will be aggregated
Example if you load
Mat001 Cust2 25 5
then the fact table will not have a new entry instead the it will aggregates and looks like (bolded one)
MATDIM    CUSDIM       AMT      QTY
1               1                  100        10
1               2                  220        10
Hope its clear
thanks
