Timesten TT8151 replication role disallows

Hi, all.

We are getting below error messages for timesten

[SubscriberOperationManager::handleDatabaseExceptio n] [TimesTen][TimesTen 11.2.2.4.1 ODBC Driver][TimesTen]TT8151: ROOT.DEDICATED_ACCOUNT's replication role disallows the requested operation -- file "eeDML.c", lineno 9494, procedure "sbEeUpdateEval"

We use two way replication. Is there any explanation on what can cause this, and what can we do to avoid such errors?

Thanks...
