Transactional Data questions

Question

We have some data issue with transactional data. We are loading Inventory data to DSO (Full load) --> Cube (Delta load) daily. Here is an example what our data issues are:
Day 1
ITEM               QTY
00001              4
Day 2
ITEM               QTY
00001              200
Day 3
ITEM               QTY
00001              100
We would like to see 200 overwrites 4 on Day 2, and 100 overwrites 200 on Day 3.
The results I got is
Day 1               4
Day 2               196
Day 3               96-
Can anyone explains me why it does this and how to overwrite the previous day's QTY instead of calculation on it? Thank you!

Hi Qingbo,
Refer to this link:
http://help.sap.com/saphelp_nw04s/helpdata/en/a0/eddc370be9d977e10000009b38f8cf/frameset.htm
It talks about the overwrtie option in the Transformation Rules, such as this:
<i>Update
Transformation rules define the rules that are used to write data to a DataStore object. They are very similar to the transformation rules for InfoCubes. The main difference is the behavior of data fields in the update. When you update requests into a DataStore object, you have an overwrite option as well as an addition option.
See also Transformation Type.
The delta process that is defined for the DataSource also influences the update. When loading files, the user must select a suitable delta process so that the correct transformation type is used.
Unit fields and currency fields operate just like normal key figures, meaning that they must be explicitly filled using a rule.</i>
and this as well:

Hope this helps.
