If the mapplet includes a transformation that uses a connection, then the PowerCenter XML file must contain only one workflow, one Session task, one mapping, and one mapplet.

The session can use any type of connection.

You do not have to map all source and target fields in the PowerCenter mapping.

The PowerCenter mapplet can contain the following supported transformations:

Aggregator transformation
Expression transformation
Filter transformation
HTTP transformation
Lookup transformation
Salesforce Lookup transformation (multiple matches returns a single match)
Salesforce Picklist transformation
Salesforce Merge transformation
Sorter transformation
Stored Procedure transformation with exception handling
Transaction Control transformation
Web Services consumer transformation
XML Generator transformation with flat file or database sources
XML Parser transformation with flat file or database sources

If you use a mapplet in a

synchronization

task, the PowerCenter mapplet cannot contain multiple Input transformations.

If you use a mapplet in a

mapping

task, the PowerCenter mapplet can contain multiple Input transformations.

Data Integration

flattens PowerCenter mapplets with multiple input groups into mapplets with one input group. Therefore, the ports in each input group in the PowerCenter mapplet must have unique names. If the names are not unique, rename the input ports in PowerCenter before you export the PowerCenter XML file that contains the mapplet.

The PowerCenter mapplet cannot contain reusable objects such as shortcuts because

Data Integration

does not use a repository to store reusable objects. Export the mapplet without reusable objects.
