Hi All, I have two groups with data link in rdf. I create one formula column in first group which using a column from second group in it. So the following error occurred. REP-1517: Column 'CF_TEST' references column 'dep_retirements', which has incompatible frequency dep_retirements is a column from second group. But I created this formula column CF_TEST in first group. So how can I achieve this?
