• You are using ABAP system as the UME datasource.

Start the ConfigTool and enable the editor mode
Navigate to cluster_config -> system -> custom_global -> cfg -> services -> com.sap.security.core.ume.service -> Propertysheet properties
If "ume.persistence.data_source_configuration" is set to dataSourceConfiguration_abap.xml, then you are using the ABAP as the datasource.
