Hi,
Once we are loading delta loads and planned to load some missed or wring entries, then always need to go with Repair full request info pack load. thru repair full request we can reload missed records(in your case kf which are 0 records) with proper selections.
You need to find the records which are have 0 at cube level.
do the selective deletion at info cube level.
delete and fill your setup tables.
run info pack with Repair full request - Go to your info pack, menu scheduler --> Repair full request.
if you see that option as disable mode, create new info pack and go for the same path.
Deleting and filling setup tables never disturb your delta pointer.
Thanks
