UDS and the Data Mapper (Magic xpi 4.9)

When you are working with the Data Mapper utility, you can use UDS in several ways:

1. Variable. You can define a variable based on a UDS model and use it in the Source and Destination of the Mapper. This means that all the data stored in the UDS variable will be treated as one BLOB.

2. Static UDS. When you access the Mapper UDS Source/Destination type, you can select the required UDS model and UDS variable and use it in the Mapper in the same way that you would use any other compound. Enter the Source Name or Destination Name, and select UDS from the drop-down list in the Type column. When you select UDS, the Data Mapper has the following properties:

   • UDS Model Name. This is the UDS model definition name.

   • UDS Variable. This is the variable name that contains the UDS data. If you select a UDS variable from the list, the Dynamic UDS option is disabled.

   • Dynamic UDS. This is the dynamic UDS name that you want to use.

   • UDS Index (for Source only). This lets you select the index to be used if one or more indexes were defined in the UDS model.

   • Append UDS (for Destination only). This lets you append data to an existing UDS variable.

3. Dynamic UDS. You can define the UDS variable name dynamically using the Expression Editor. The expression will be calculated at runtime and must reference an existing UDS variable. This option is only enabled if you do not select a variable in the UDS Variable field.
