BW Monitor indicates no data selected, But RSA3 in the source sys is +ve

Hi,

I am working with a percticulat bsuiness content ODS object and all the necessary object to load data into it are activated properly. Related master data is loaded already. However while trying to load data into the ODS I have found that the monitor( header and detail message) indicating that there is no data in the source system. But while checking with the RSA3 in the siurce system I found data are being extracted.

Can any body help me what exactly going on here or am I missing certain things here?

Thanks
