cannot load data into cube

Dear All:

I was just trying to create a copy of 0D_SD_C03. I went to the cube and generated export datasource. I found 80D_SD_C03 in my datamart subtree. I then replicated datasources. When I tried to load data into the new cube, it stopped and gave a message "Data not received in the PSA table" in the Monitor. On the Detail tab it says 10945 records sent and 0 records received. Thaks for your help.
