When you import source definitions from SAP, the Designer uses RFC to connect to the SAP application server. The Designer calls functions in the SAP system to import source definitions. SAP returns a list of definitions from the SAP dictionary. You can select multiple definitions to import into the PowerCenter repository. The Designer imports the definition as an SAP ECC source definition. After you import a definition, use it in a mapping to define the extract query.
You can import the following definitions into the PowerCenter repository:
SAP tables and views.
SAP tables include transparent, pool, and cluster tables. In addition, you can extract data from database views in SAP.
SAP hierarchies.
A hierarchy is a tree-like structure that defines classes of information.
SAP IDocs.
An IDoc is a generated text file that contains a hierarchical structure consisting of segments.
If the source changes after you import the definition, reimport the definition as a new SAP ECC source definition.
Informatica recommends that you use PowerExchange for SAP Dynamic ABAP Table Extractor to read data from SAP tables and ABAP Core Data Services (CDS) views through HTTP/HTTPS streaming.
