0fc_ci_01 cleared items data source

Hi Experts,

I am Using BW 3.5

I am extracting full load every month from Cleared Items data source (0fc_ci_01) since go live. Approximately 70 millions of data is being loaded every month into ISU to BW.

Procedure which I am Following is as follows:

I run a Mass run(fetches data from golive date to current date) to populate intermediate staging tables in IS-U

Once this is completed I start extraction to BW with different ranges which takes approximately 8-9 working days.

Now my question is Can I do psuedo Delta every month after One Full load.

Will it be feasible for this data source (0fc_ci_01).

Please Give me some insight into this.

Warm Regards,

Nanduri Aditya
