You can perform data lineage analysis between SAP R/3 tables and PowerCenter mappings in Metadata Manager. Metadata Manager does not extract the data lineage information between SAP R/3 variables and functions.
In addition, if you manually edit an ABAP program for an Application Source Qualifier in a PowerCenter mapping, data lineage analysis does not include any tables manually included in the Application Source Qualifier. For example, if you override an ABAP program to include an SAP R/3 table not included as a source in a PowerCenter mapping, Metadata Manager does not display the lineage between the PowerCenter mapping and the SAP R/3 table.
