Edition Valid to Issue

Hi

SAP help documentation says that

When you create an edition, the system automatically determines the date to which the edition can be valid so as to eliminate any time overlaps with existing editions. A previous edition will only be valid until the Valid from date of the new edition.

But in MDG7.0 with SP06 I created two editions with same edition type 0G_ALL

Edition 1 with valid from 01012003 and system defaulted valid to date is 31129999.

Edition 2 with valid from 01012004 and system defaulted valid to date is 31129999.

Now as per SAP logic changes automatically happens for Edition 1 valid from date is 01012003 and valid to date is 31122003.

But it seems from USMD020C (Edition Table) still

Edition 1 with valid from 01012003 and system degfaulted valid to date is 31129999.

Edition 2 with valid from 01012004 and system degfaulted valid to date is 31129999 and both the editions with status In process.

It is happening for MDG6.1 but not for MDG7.0. Any reason for this?
