GDC: Scan job using multiple criteria ignores some criteria

• Article Type: General

Problem Symptoms:
* Scan job using 3 rules in a Scan Rule Set, first is used and other two are ignored.

Cause:
When multiple scan rules are used, the GDC's logic is to OR them. Must use Exclude conditions or multiple jobs to AND the conditions.

Resolution:
In order to obtain a record set with all three conditions, you can use 1 of 2 methods.
Example: Resulting record set would contain records that meet the following criteria:
008/07 equals 2010
008/06 equals s
008/15 equals nyu

Method 1: Use Exclude Consequence
1. Create first rule with Include consequence.
2. Create second and third rules with Exclude consequence.
Example:
When 008/07 equals 2010, include
When 008/06 does not equal s, exclude
When 008/15 does not equal nyu, exclude

Method 2: Multiple Scan Jobs
1. Put each condition in a separate Scan Rule Set and Scan Rule Set Group.
2. Run multiple scan jobs to apply each criteria sequentially.
Example:
Scan job 1: Scan entire database and when 008/07 equals 2010, add to record set XYZ
Scan job 2: Scan record set XYZ and when 008/06 equals s, add to record set XYZ-2
Scan job 3: Scan record set XYZ-2 and when 008/15 equals nyu, add to record set XYZ-3 - record set XYZ-3 will contain only records that meet all 3 conditions.
