Hi,
if you already initialized your data source then you don't need to fill set up tables.
Set up table will be filled when we load full load or init with data transfer.
if you data source have delta pointer at RSA7 then you dont need fill set up tables.
if you got yester dayt thru delta then today you can delta load at 10AM, you may see the the data which was created yesterday.
Assumed as you set whole data flow active and in proper settings(V3, job control,delta etc.)
Thanks
