We are just in upgrade process from 4.7c to ECC 6.0. During the test we ascertained that there are certain changes happened in the reporting functions und the reports are not showing some necessary fields in new version. For instance the reports RFDOPO00 and RFKOPO00 are replaced by RFDEPL00 and RFKEPL00 in ECC 6.0, which do not show some important fields of old report. SAP says they are standard reports in ECC 5.0 /6.0.
How can we maintain old reports (in general, not specifically these above mentioned reports) from 4.7c in our new upgraded system ahead instead of new reporting standard of ECC6.0.
Please tell me the steps to solve this problem.
