Have you mapped the fiscal year variant with s ource field or if you know the variant then you can also harcode the same as constant value in transformation.
ALso check the value you are getting from the source field SPMON.
Internal format should be 2014001.Check the same.
Moreover SPMON consists of year and month in the internal format 201405 so this has to be mapped to 0calmonth instead of 0fiscper.
