Hi,
First lets check your data flow.
how the data exist at RSA3 source side, next at psa level, go on upto last target level.
You need to check data is exist after 02.02.2015 at dev system or not.
About 0calday - Check how you maintained master data?
if you have data flows to 0calday then you can load it. Other wise you can maintain by your at 0calday level. But as my guess these all dates/years must be maintained at end of december itself by FI team.
Just cross check at prod and compare with dev.
