How to create a New SD flow in SAP BI

Hi Experts,

I want to create new SD flow where all data will be going to Standard Cube : 0SD_C03.

Our dataflow is like this : Datasource --> DSO --> Cube (0SD_C03).

There are many datasource for which Standard DSO is not available and we need to create Custom DSO. Is there any way to know which fields from Datasource will be mapped to Custom DSO.

Below are the datasource used and there Standard DSO.

1. Datasource ( 2LIS_11_VAHDR) ---> Standard DSO : 0SD_O03 (Orders)

2. Datasource ( 2LIS_11_VAITM) ---> Standard DSO : 0SD_O01 (Order Items)

3. Datasource ( 2LIS_11_V_I_TM) ---> Not able to find Standard DSO.

4. Datasource ( 2LIS_12_VCITM) ---> Not able to find Standard DSO.

5. Datasource ( 2LIS_12_VCHDR) ---> Not able to find Standard DSO.

6. Datasource ( 2LIS_13_VDITM) ---> Not able to find Standard DSO.

7. Datasource ( 2LIS_13_VDIHR) ---> Not able to find Standard DSO.

Please let me know if there is any Standard DSO available for the above datasource. If not then how we will be able to map the Datasource Fields to Custom DSO? Is there any table which will provide or something like that?

Thanks !!!
