By default, Qlik Replicate tries to use Microsoft SQL Server native replication feature to support capture changes from the SQL Server source.
When we start the Qlik Replication task with SQL Server as a source, Qlik Replicate will verify that the MS Replication feature is enabled or not, and once all the pre-requisites are met Qlik replicate will try to create the publication with the name AR_PUBLICATION_XXXX where XXXX represents the dbid of the Replicated database as shown in the below picture.
Note: Each time when we stop and resume the task, Qlik Replicate will verify whether the publication exists with the name AR_PUBLICATION_XXXX and if the publication does not exist then Qlik Replicate will automatically create the publication with the name AR_PUBLICATION_<dbid>.
