I am working with a BW system that gets data from two different R/3 systems to different PSAs, consolidated in ODS1, then moved to ODS2 and the finally to a cube. The data is extracted randomly, when the maximum packet size is reached, to the PSA and then for every 15 days the data is loaded as deltas into the ODS1,ODS2 and Cube(at the same time).Now we want the deltas are to be loaded into the ODS1, ODS2 and cube every day instead of every 15 days. We are actually using a factory calender that the routine uses when loading data. I think I need to make changes to the factory calendar or make a new one or write a new program. Can somebody please suggest me how to do that and what precuations need to be taken.
