Factory calendar table "TFACD" accessed by fm holiday_get only goes to 2010
I am using the holiday get function module and enter a "date_to" field of 20120101 a "date_from" of 20100101 and a factory calendar of 'GB'. However it only returns holidays up until end of 2010. I have debugged and discovered that it relies on an entry in table "TFACD". I have looked and the field TFACD-BJAHR = 2010 i.e. date to only goes up to 2010.
Firstly, how and when does this table TFACD get updated?
Secondly, is there a way to get bank holidays for years 2011 and onwards?
Thanks in advance!
