DS_USECOLPREC_FOR_DECIMAL_KEY
Set the environment variable DS_USECOLPREC_FOR_DECIMAL_KEY=1 so that key columns of datatype DECIMAL use the precision specified in the column metadata.
If DS_USECOLPREC_FOR_DECIMAL_KEY is not set, the default
system precision specified in the uvconfig file
is used when writing data to DECIMAL key columns in server jobs, and
in server shared containers in parallel jobs.
