You can generate DATA step (DS1) code or DS2 code for a
rule flow. In many cases, you will get better performance by specifying DS1. However, consider
specifying DS2 if your input data is in Teradata, Greenplum, or Hadoop, and you have
installed the SAS Code Accelerator. In addition, the LIKE
operator is not supported for DS1.
The
brm.runtime.codetype configuration
property in SAS Management Console determines whether SAS Business Rules Manager generates
DS1 code or DS2 code during rule flow testing and when a published rule flow is run.
By default, this property is set to
DS2. You can change this property to specify DS1.
See Business Rules Manager Web Advanced Properties in SAS Business Rules Manager: Administrator’s Guide for more information.To generate DS1 code for a specific rule flow regardless of the setting of the
brm.runtime.codetype property,
you can specify the &BRM_CODE_TYPE macro variable in preprocessing
code. Define this variable in preprocessing code such as in the
Preprocessing
Code section of a
rule flow test or in the
Precode section
of the
Precode and Postcode tab in SAS Data
Integration Studio. Define this variable before calling the %BRM_RULE_FLOW
macro:
%let BRM_CODE_TYPE=DS1;
Using
this macro variable helps you determine whether you want to change
the
brm.runtime.codetype setting.
