Hi,
Your data source have delta pointer. then why your using T-code - OLI1BW ?
Filling setup tables only use full when we load data thru full load or repair full request.
You need to check at SMQ1/LBWQ/SM13/RSA7 - some where records will be exist. so it won't allow you to fill setup tables. if All queues have 0 records then only we can fill setup tables.
Mean while try to delete setup tables data thru LBWG and later try to fill set up tables.
Thanks
