An output field can be filled by the following methods:

• Conversion of an input field according to the respective data types
• Processing of data from input fields using predefined functions
• Insertion of fixed values or creation of dynamic values during the replication process

Conditions control the processing on a field and data record level:

• A field-to-field-replication is only performed under certain conditions
• The replication of a data record is only performed under certain conditions

Symbols drawn to the lines represent different states:

• : Condition defined
• : Processing defined
• : OCCURS index
• : Action related

The field of an output table is filled with the data from an input table. A connecting line between the two fields is displayed in the RDRS Dashboard:

In an action-related replication, an output field is populated based on properties of the current replication event (such as the originating source, the type of operation, or a generated index). The RDRS Dashboard indicates this with a specific symbol at the output field.

The source for such a replication can be:

• The index to resolve an OCCURS field table at the input table
• Replication coming from a certain input table
• Replication to this output table

In the above example, field WCUUSER is assigned the constant value RDRS. For more information, see Replication Processing. Field WCUDTTI receives the current processing timestamp. These assignments are always performed when the change originates from input table C01103, regardless of whether the output field is connected to an input field.
