Hi,
You can use compcode or fiscperiod.
if you have huge data for full loads, in that case you can use fiscperiods or calmonth
about special periods - you can consider and load it. if source have data then it will pulls.
Major point here you need load all records without missing single one.
Other wise do one thing.
1. Do full loads with any selections
2. run info pack init without data
3. you can run delta info pack pas per needs.
if possible try to load at weekends where there is no business.
Thanks
