Tthanks Michael.
I will check it out. This note explains the logic very clearly which I think we have got it. But it is still a great knowledge note. Our issue is MD04 in ECC showing the cor react date and CO09 in APO for the same material ALWAYS showing ONE DAY LESS. Our CO09 branches to APO as we have CTP in 8 plants. The non CTP Plant materials for whom both MD04 and CO09 is executed in ECC the dates are perfect. Some users use MD04, some CO09 and most CSRs use both. So they are confused with different dates coming out of the system and their worry is some 'promissable' dates could be missed. If you need I can post screenshots on Monday.
Thanks again,
