SAS/ACCESS works by interfacing with thestream driver through the TPT API, which in turn uses the Teradata Multi-Statementinsert (TPump) protocol for loading data. See your Teradata documentation for moreinformation about the stream driver.This is the default Multi-Statement insert method. If SAS cannot find the Teradatamodules that are required for the TPT API or TPT=NO, then SAS/ACCESS uses the oldmethod of Multi-Statement insert. SAS/ACCESS can restart Multi-Statement insertfrom checkpoints when Multi-Statement insert uses the TPT API.The SAS/ACCESS Multi-Statement insert facility loads both empty and existingTeradata tables. SAS/ACCESS supports only insert operations and loading only onetarget table at time.Errors are logged to Teradata tables. Error recovery can be difficult if you do not setTPT_CHECKPOINT_DATA= to enable restart from the last checkpoint. To find theerror that corresponds to the code that is stored in the error table, see your Teradatadocumentation. You can restart a failed job for the last checkpoint by following theinstructions on the SAS error log.Starting Multi-Statement Insert with the TPT APISee the SAS configuration document for instructions on setting up the environmentso that SAS can find the TPT API modules.You can use one of these options to start Multi-Statement in the SAS/ACCESSinterface using the TPT API:3 the TPT=YES data set option in a processing step that populates an emptyTeradata table3 the TPT=YES LIBNAME option on the destination libref (the Teradata DBMSlibrary where one or more tables are to be created and loaded)Multi-Statement Insert with TPT API Data Set OptionsThese data set options are specific to Multi-Statement insert using the TPT API.
