0CALDAY

Hi experts-

How can I get data into 0CALDAY in following scenarios. Given that I have chosen 0CALDAY as time characteristic in my InfoCube definition.

ONE: I have filed (mm/dd/yy) in my flat file.

TWO: I have ODS object that has Data filed (an InfoObject) of type CHAR. (This is actually feeded from the file).

I am not sure do I need to create any InfoObject corresponding to this date field in my InfoCube and then assign (don't know how) to 0CALDAY.

I appreciate your help.

Thanks.
