VK34, problem of warning issued upon new condition:Reason codes inconsist

Question

Hello,
The Scenario is :
for a given material/sales organisation
1- I create a ZP00 condition  value =100$  valid from 01.09.2009  to  31.12.2009
2- I create new ZP00 condition value= 160$  valid from 01.01.2010 to 31.12.2999
To day, I decide to change the ZP00 condition value,
3- I created a new ZP00 condition with value=160$  valid from 11.09.2009 to 31.12.2009
The system doesn't issue any warning message to tel me that there is a gap in value between the new condition and the old condition valid for the same period
In fact the system compare the new condition value with the last created condition, hence it doesn't find any difference, and as consequence no warning is issued.
I expect that system compares the new condition value to the condition value valid for the same period and not the last condition
==> Shall I post an OSS for this problem ??
