During PowerExchange change capture processing of the specified Microsoft SQL Server source distribution database, an SQL call to delete the rows of data that PowerExchange processed from the distribution database as a result of a low water mark action failed. This error can occur only when the ENABLELWM parameter is set to Y in the MSQL CAPI_CONNECTION statement in the dbmover.cfg file. This setting causes the consumer API (CAPI) to delete all of the processed data for the PowerExchange publications from the dbo.MSrepl_commands table, after the PowerExchange Logger has hardened the data. However, some or all of the processed rows in the dbo.MSrepl_commands table could not be deleted.
