Filling setup tables for customised datasources

Hello All,

I wish to load certain records that have been missed while loading data in the past month. I am aware that we can fill the setup tables and get data into BW till PSA with a full upload and then a repair full.

But can you please tell me stepwise how can I fill the setup table for a completely customised datasource?

I am trying to load transactional data - billing data.

Please help.

Regards,
