Rules and Guidelines for Object Compatibility

Rules and Guidelines for Object Compatibility

The Repository Service treats modified dependent objects as compatible when you perform the following tasks:
  • Change datatypes in a source, target, or transformation to a compatible datatype. The Repository Service marks objects as impacted only when you change the datatypes to incompatible datatypes.
  • Rename ports in a reusable transformation.
  • Add a port in a source, target, or transformation.
  • Replace objects such as sources, targets, mapplets, and mappings with compatible objects.
When you replace a repository object with another object, the following conditions must be true for the Repository Service to treat the objects as compatible:
Repository Object
Compatibility Requirements
Source, Target, Transformation
  • Name of the replacement object must match the original object.
  • All port names in the original object must be represented in the replacement object.
  • Datatypes must be compatible.

  • Targets
