Using Emulated 3.x DataSources
You can display an emulated 3.x DataSource in DataSource maintenance in BI. Changes are not possible in this display. In addition, you can use emulation to create the (new) data flow for a 3.x DataSource with transformations, without having to migrate the existing data flow that is based on the 3.x DataSource.
We recommend that you use emulation before migrating the DataSource in order to model and test the functionality of the data flow with transformations, without changing or deleting the objects of the existing data flow. Note that use of the emulated Data Source in a data flow with transformations has an effect on the evaluation of the settings in the InfoPackage. We therefore recommend that you only use the emulation in a development or test system.
Constraints
An emulated 3.x DataSource does not support real-time data acquisition, using the data transfer process to access data directly, or loading data directly (without using the PSA).
If you want to use transformations in the modeling of the data flow for the 3.x DataSource, the transfer rules and therefore the transfer structure must be activated for the 3.x DataSource. The PSA table to which the data is written is created when the transfer structure is activated.
To display the emulated 3.x DataSource in DataSource maintenance, highlight the 3.x DataSource in the DataSource tree and choose Display from the context menu.
To create a data flow using transformations, highlight the 3.x DataSource in the DataSource tree and choose Create Transformation from the context menu. You also use the transformation to set the target of the data transferred from the PSA.
To permit a data transfer to the PSA and further updating of the data from the PSA to the InfoProvider, select the DataSource 3.x in the DataSource tree and choose Create InfoPackage or Create Data Transfer Process in the context menu. We recommend that you use the processes for data transfer to prepare for the migration of a data flow and not in the production system.
If you defined and tested the data flow with transformations using the emulation, you can migrate the DataSource 3.x after a successful test.
