System Parameter Conversion

You can import a PowerCenter mapping or mapplet that contains some system-defined parameters. The import process imports the parameters if they match the system-defined parameters that are valid in the Model repository.

The import process creates the parameter bindings between the system-defined parameters and the reusable transformations that reference the parameters.

If a PowerCenter mapping has a system-defined parameter that does not have an equivalent system-defined parameter in the Model repository, the conversion does not fail. The import process copies the mapping property with the parameter name as the property value. However, the imported mapping is not valid. You can create a user-defined parameter to replace the property value or you can change the mapping logic.

You can import the following system-defined parameters:

$PMMappingName

$PMIntegrationServiceName

$PMRepositoryUserName

$SESSSTARTTIME

$SYSDATE

You cannot import the following PowerCenter system-defined parameters:

$PMFolderName

$PMRepositoryServiceName

$PMSessionName

$PMSessionRunMode

$PMTAB_ALL_DATA_TYPES@TableName

$PMTGT_ALL_DATA_TYPES@TableName

$PMWorkflowName

$PMWorkflowRunId

$PMWorkflowRunInstanceName

When a property is assigned a system parameter in the PowerCenter repository, the import process might not be able to convert the system parameters. The import process might set the default parameter value in the Model repository and you cannot edit the property value in the imported mapping.
