Salesforce Dynamic Mapping Overview

Salesforce Dynamic Mapping Overview

You can use Salesforce data objects as dynamic sources and targets in a mapping in the native environment.
Use the Salesforce dynamic mapping to accommodate changes to source, target, and transformation logics at run time. You can use a Salesforce dynamic mapping to manage frequent schema or metadata changes or to reuse the mapping logic for data sources with different schemas. Configure rules, parameters, and general transformation properties to create the dynamic mapping.
If the data source for a source or target changes, you can configure a mapping to dynamically get metadata changes at runtime. If a source changes, you can configure the Read transformation to accommodate changes. If a target changes, you can configure the Write transformation accommodate target changes.
You do not need to manually synchronize the data object and update each transformation before you run the mapping again. The Data Integration Service dynamically determines transformation ports, transformation logic in the ports, and the port links within the mapping.
You can select one of the following options to enable dynamic mapping:
  • In the
    Data Object
    tab of the data object read or write operation, select the
    At runtime, get data object columns from data source
    option when you create a mapping.
    When you enable the dynamic mapping using this option, you can refresh the source and target schemas at runtime.
    You cannot refresh the schema for Salesforce lookups at runtime.
  • In the
    Ports
    tab of the data object write operation, select the value of the
    Columns defined by
    property as
    Mapping Flow
    when you configure the data object write operation properties.
