In SAS^® Viya^® 3.4, trying to load a Teradata table into CAS might result in an error when you include the dataTransferMode='parallel' option using one of these three methods:

• the datasource= option in the CASLIB statement
• the options= option with the LOAD statement and the CASUTIL procedure
• the dataSourceOptions= option with the table.loadTable action

The error might look similar to the following:

The error occurs when the primary key on the Teradata table is defined as an INTEGER, FLOAT, or DECIMAL data type and you are using TTU 16.20.30. The VARCHAR, SMALLINT, and BIGINT data types do not have this issue.

A workaround for this issue is to downgrade the Teradata client on the CAS Controller/Worker nodes to TTU 16.20.19 or TTU 16.20.29.
