Hi Sandeep,
I have not worked on this datasource but yes technically you can do it.
As I understand, 2LIS_02_SCL is for header details of PO and PO has one to one relationship with Material Doc number.
Therefore, if you requirement is to only bring in the header details for this Material doc, only enhance this datasource.
Append this field to the datasource, then write the customer exit for this datasource.
In this customer exit, you can write your code for deriving the Material doc number from EKBE based on the details available in e_t_data (for this datasource).
But, if your requirement is to fetch line item details as well, you need to append the other datasource as well. And by writing the exit you can again derive the details from the table.
Please note that the appended fields cannot be used to trigger any deltas, so if your requirement includes to trigger the delta if your material document changes, it cannot be done.
Hope this helps.
