Hi,
When a report which is running fine in 8.2 is migrated to 8.4 it is displaying an error message RSV-VAL-0003 Unable to find the data item in the query.However the report is running fine.Any ideas why this issue.
Thanx

Could be caused by the change in query build by Cognos. Early Cognos 8 versions would add the dataitem to the query regardless whether they were used in a datacontainer,layout or variable.  In 8.4 non-used dataitems are stripped from the query unless you actively decide to have them fetched..
