RDF Calc Rule Groups

Hi,

I understand load, calc, commit and referesh rulegroups execute real time while creating the workbook or during the workbook creation. There are couple of base rule-groups with RDF solution.

For example:

FAP_calc_F01 which looks like for the forecast final level 1. Where exactly this calc rule group does execute. Does it execute as part of generate forecast or it does execute real time (workbook creation)? Similarly there are load, commit and refresh as well available for every final level defined in the automation plug-in (where exactly they are getting executed)
