As of release r18 there was an enhancement to the Saved Reports functionality, that could help avoid or resolve these problems after an upgrade to DB2?
The Synchronize Save Report enhancement provides an option to upgrade saved reports from a previous version of DB2.
A user that has saved reports in RC/Query, can enter the REPORTS command on any RC/Query panel. Then on the RC/Q Customized Report Formats panel, the version of each report will be displayed and the synchronize option can be used:
Synchronize Save Report Profile ===> N (Y/N)
This will upgrade saved reports created in a lower version to the higher version of DB2.
Please note the warning, if you intend to use 'Synchronize Save Report = Y', do not use line commands on the saved reports.
