Mappings and Mapping tasks with SAP BW overview

Use a mapping to define data flow logic that is not available in synchronization tasks, such as specific ordering of logic. Use the Data Integration Mapping Designer to configure mappings.
You can create a mapping to read data from an SAP BW source. You cannot perform a lookup on an SAP BW object.
When you configure a mapping to describe the flow of data from a source to a target, you can also add transformations to transform data. A transformation includes field rules to define incoming fields. Links visually represent how data moves through the data flow.
After you create a mapping, you can run the mapping or you can deploy the mapping in a mapping task. You can use the Mapping application to process data based on the data flow logic that you defined in the mapping.
Use the Mapping Task wizard to create a mapping task. When you create a mapping task, you can select the mapping based on which you want to create the task.
If you configured parameters, which are placeholders for information, in a mapping, you can define the parameters in the mapping task. You can define parameters for additional flexibility and to use the same mapping in multiple mapping tasks. For example, you can use a parameter for a source connection in a mapping, and then define the source connection when you configure the mapping task.
When you create a mapping task, you can associate the task with a schedule to run it at specified times or at regular intervals. Or, you can run it manually. You can also configure advanced session properties. You can monitor tasks and view details about completed tasks.
