Hi Asim,
Please check the application area for which you want to full upload also check for the respective selection parameters as well to execute the job in ECC.
Before filling setup table make sure you empty it.
Since you said that you missed out some delta so no need to reinitialise it, if you can identify the date range of missed delta it would be better. Once the data will appear in setup table execute the infopackage to pull data in BW.
Hope this helps.
Regards,
