Delta loading procedure from Write Optimized DSO to Infocube

Hi All,

We are using Write optimized DSO in our project to which I am loading data using Standard DSO 0FI_GL_12

From Write optimized DSO, we are loading delta records into Infocube, please provide your inputs to my following questionnaire:

1) I am quite interested to know how the delta records gets loaded into infocube whenever we are using 'Write optimized DSO' as we don't have any image concept in Optimized DSO

Ex: If am using Standard DSO, we have Change log table and image concept will allow to get updated value to Cube

let us assume

Active Table

111            50

111            70 (overwrite)

Change Log Table

111            -50        (X -- Before Image)

111             70    ( '  ' -- After Image) symbol for after image is 'Space'

So if we load this record to the target as a delta the above two records from change log table will get loaded to the CUBE and Cube will have 70 as the updated record

If am using 'Write Optimized',

Active Table

111            50

111            70 (overwrite)

When this record loaded to the cube, as Info Cube is always having 'Additive' feature so the total value will 50+70 =120 which is wrong?

Correct me what feature will work here to get updated value as '70' into Cube from Write Optimized DSO'

2)As the data source is delta capable and having  'ADDITIVE' delta process, only the delta records based on REQUEST ID are loaded into Info Cube with the  updated key figure value?

Thanks for your inputs and much appreciated.

Regards,

Madhu
