Custom Transformation

You can include a Custom transformation in a mapping template or import a template from a mapping with a Custom transformation.

You can configure the properties and create input and output groups for the Custom transformation. When you include a Custom transformation in a mapping template, you can set it to an active or passive Custom transformation. Set the IsActive property to Yes for an active Custom transformation, and set the property to No for a passive Custom transformation.

The following table describes the required properties and values for an active or passive Custom transformation:

Transformation Property	Description
Transformation Name	Name of the transformation.
Language	Language used for the procedure code.
Runtime Location	Location that contains the DLL or shared library. Default is $PMExtProcDir.
Tracing Level	Amount of detail displayed in the session log for this transformation. Set the value to Normal for both active and passive Custom transformations.
Is Partitionable	Indicates if you can create multiple partitions in a pipeline that uses this transformation. Set the value to No for both active and passive Custom transformations.
Inputs Must Block	Indicates if the procedure associated with the transformation must be able to block incoming data. Set the value to Yes for both active and passive Custom transformations.
IsActive	Indicates if this transformation is an active or passive transformation. Set the value to Yes for an active Custom transformation, and No for a passive Custom transformation.
Update Strategy Transformation	Indicates if this transformation defines the update strategy for output rows. Set the value to No for a passive Custom transformation. For an active Custom transformation, you can set the value to Yes or No.
Transformation Scope	Indicates how the Integration Service applies the transformation logic to incoming data. Set the value to All Input for an active Custom transformation and Row for a passive Custom transformation.
Generate Transaction	Indicates if this transformation can generate transactions. When a Custom transformation generates transactions, it generates transactions for all output groups. Set the value to No for a passive Custom transformation. For an active Custom transformation, you can set the value to Yes or No.
Output is Repeatable	Indicates if the order of the output data is consistent between session runs. Set the value to Never for an active Custom transformation and Based on Input Order for a passive Custom transformation.
Requires Single Thread Per Partition	Indicates if the Integration Service processes each partition at the procedure with one thread. Set the value to Yes for both active and passive Custom transformations.
Output Is Deterministic	Indicates whether the transformation generates consistent output data between session runs. Set the value to Yes for both active and passive Custom transformations.
