To create an SAP BW OHS Extract data object, import metadata from an open hub destination or InfoSpoke into the Developer tool. Create a data object read operation based on the data object. Then, configure the read operation properties to determine how the Data Integration Service must read data from SAP BW.

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