When you select the instance name, you can create a breakpoint for an individual transformation, or you can create a global breakpoint:
Transformation instance.
Select a transformation from a mapping or mapplet to configure a breakpoint condition that the Integration Service evaluates when it processes that transformation. The naming convention for transformations within mapplets is
MappletName.TransformationName
.
Global instance.
Select Global to configure a breakpoint condition that the Integration Service evaluates when it processes each transformation in the mapping.
