To create an SAP BW Load data object, import metadata from a 3.x data source or 7.x data source into the Developer tool. Create a data object write operation based on the data object. Then, configure the write operation properties to determine how the Data Integration Service must write data to SAP BW.

After you configure a write operation, you can create a mapping to write data to SAP BW. Add the write operation as a target in the mapping. You can then add a source and transformations in the mapping.

Create a workflow based on the mapping. Then, create an application based on the workflow and deploy the application to the Data Integration Service.
