Replication Method, Scheduler Subjob

This field specifies the replication method performed in data exchange. There are 2 options:

Normal - For a scheduler job, a normal data exchange means that data is exchanged between tables by comparing two tables and making them identical. Since this method often requires reading all table records in both databases, it is not recommended for big tables. However, for tables that neither create Actions nor have Replication Counter, and from which records may be deleted, normal replication is the only option. The exchange is further specified in the What To Do field.

By Actions - The system uses the Actions table to send only the exact changes that have been made to the From-Table ID to the To-Table ID. Using this method limits the number of records that need to be replicated. The method cannot be used in replication from stores to head office without modifications.

A third type of replication method is specified by selecting the normal option and selecting a Replication Counter for the subjob. A normal replication with Replication Counters, limits the number of records replicated each time. Records that are deleted from a table replicated with Replication Counter, will not be deleted from the table in the database replicated to.
