Date characteristics wrong

Hello All

When i execute the report in BEx, i get a error pop up sayin that the "Value '16.09.20' of 0DATE Characteristics is not a number with 000008 spaces.

Error Reading Info Provider , Error while reading the data.

The report is based on a consolidate dso, which is getting fed by 2 dso's. I tried checking the date fields of all the date characterisitcs present in the dso, but i dont find this Date.

Can any 1 advice me, how to find this date value??

thanks
