Problem Note 54454: The generated DS2 code for a rule flow might not be correct when the code has more than one rule set with one rule set containing OR logic
 |  |  |  |  |
SAS® Business Rules Manager might not generate DS2 code correctly for a rule flow. The problem occurs when rule flow has more than one rule set, and one of the rule sets contains a rule having OR logic.
There are no errors or warnings to indicate a problem.
To work around this problem, break compound rules into separate rules.

EXAMPLE
A rule flow contains the following two rule sets.
Rule Set1: If (DAY=DAY) Then Top1=1; Top2=2
Rule Set2: If QUANTITY=1
Or QUANTITY=2
Or QUANTITY=3 Then Flag="fired"
Run a test on the rule flow. The output result is wrong. When QUANTITY=2, the term Flag should be assigned to "fired". However, the assignment is not performed. See the screen shot.
You can examine the rule flow code by opening the rule flow. Click the Tests menu item. Click the Results tab. Click Code . The action expressions are assigned incorrectly for the OR rules, as displayed in this code:
The correct code should be the following:
