How to fill a second target infocube from ods

Hi BW gurus,

We have a ODS which connect to the r3 datasource 0fi_gl_4, and perform auotmatic update to one infocube. From this month we build another infocube and want the ODS also update the new infocube. I have setup the transfer rules. But the ODS and the old infocube have a lot of data. How can I perform delta update to both cubes without deleting the old data?

Thanks
