I can not understand why in the last step, 5.), the SDE2 does not show any changes on map that are made in SDE1,
and also the compression of SDE1, SDE2, and SDE3 does not compress the A and D tables at all in any of them.
2.) copy FC from SDE1 to SDE3 (SQL Server). This only copies the base table with the original version before the edits in 1.), not the changed data in A and D tables as the default version in SDE1 is still referenced by the hidden system version. The copy/paste seems to only apply to non-referenced default version. As a result, the FC does not match between SDE1 and SDE3 in ArcMap. To prove this, I performed the next step.
Heather,
Thanks for the information. Actually I read this classic article you cited before doing the tests, but I don't see anything that can help explain the behavior that I see which can be summarized in short - if one SDE1 that has two-way replications to two other SDEs, say, SDE2 and SDE3, sync changes from SDE1 to SDE2 will immediately see the same changes in SDE2, but then sync from SDE1 to SDE3 will not show the same changes in SDE3. All are in default session and are in the same arcmap session.
