Effective in version 10.2.1, you can assign parameters to the following mapping objects and object fields:

Object	Field
Customized data object read operation	Custom query Filter condition Join condition PreSQL PostSQL
Customized data object write operation	PreSQL PostSQL Update override
Flat file data object	Compression codec Compression format
Lookup transformation	Custom query. Relational only.
Read transformation	Custom query. Relational only. Filter condition. Relational only. Join condition. Relational only. PreSQL. Relational only. PostSQL. Relational only.
Write transformation	PreSQL. Relational only. PostSQL. Relational only. Update override. Relational only.

Effective in version 10.2.1, you can resolve mapping parameters in the Developer tool. When you resolve mapping parameters, the Developer tool generates a run-time instance of the mapping that shows how the Data Integration Service resolves the parameters at run time. You can run the instance of the mapping where the parameters are resolved to run the mapping with the selected parameters.

The following table describes the options that you can use to resolve mapping parameters:

Mapping Parameters	Description
Apply the default values in the mapping	Resolves the mapping parameters based on the default values configured for the parameters in the mapping. If parameters are not configured for the mapping, no parameters are resolved in the mapping.
Apply a parameter set	Resolves the mapping parameters based on the parameter values defined in the specified parameter set.
Apply a parameter file	Resolves the mapping parameters based on the parameter values defined in the specified parameter file.

To quickly resolve mapping parameters based on a parameter set. Drag the parameter set from the Object Explorer view to the mapping editor to view the resolved parameters in the run-time instance of the mapping.

Effective in version 10.2.1, you can validate mapping parameters in the Developer tool. To validate mapping parameters, first resolve the mapping parameters. When you resolve mapping parameters, the Developer tool generates a run-time instance of the mapping that shows the resolved parameters. Validate the run-time instance of the mapping to validate the mapping parameters.
