See the following scope and requirements before you reuse the transformation logic from UDFs configured in your Informatica Intelligent Cloud Services organization:
•You cannot use a UDF that is parameterized.
•If you set the UDF cascade_fields source attribute to True for a data pipeline, and a UDF in the pipeline is an active transformation that can change the number of rows that pass through the transformation, chaining of UDFs fails.
•You cannot use UDFs configured as source and target transformations in your Informatica Intelligent Cloud Services organization. You can use only those UDFs configured as other transformations, excluding source and target transformations, midstream in a data pipeline in INFACore. You can chain these UDFs either after the read operation or before the write operation.
